However, they are listed by the DS4000 storage subsystem controller firmware and Storage Manager host software releases to indicate which controller firmware and Storage Manager host software release that they were first seen and documented. New limitations with Storage Manager Installer (SMIA) package version 09.19.xx.06 release 1. Can not increase the capacity of RAID arrays. RAID arrays with certain combinations of selected segment size and number of drives that made up the arrays will exceed the available working space in controller dacstore, causing a reconfiguration request (like expanding the capacity of the array) to be denied. These combinations are generally the largest segment size (512KB) with the number of drives in the array is 15 drives or more. There is no work-around. C324144 105008 2. Interoperability problem between the Tachyon DX2 chip in the DS4500 and the DS4300 storage subsystem controllers and the Emulex SOC 422 chip in the EXP810 expansion enclosure ESMs causing up to 5 Fibre Channel loop type errors to be posted in the DS4000 storage subsystem Major Event Log during a 24 hour period. There is a small window in the SOC 422 chip that multiple devices can be opened at one time. This ultimately leads to Fibre Channel loop errors of Fibre Channel link up/down, Drive returned CHECK CONDITION, and Timeout on drive side of controller. IBM recommends the use of the Read-Link-Status function to monitor drive loop for any problems in the drive loop/channel. There is no work-around. 3. The single digit of the Enclosure IDs for all enclosures (including the DS4000 storage subsystem with internal drive slots) in a given redundant drive loop/channel pair must be unique. For example, with four enclosures attached to the DS4300, the correct enclosure ID settings should be x1, x2, x3, and x4 (where x can be any digit that can be set). Examples of incorrect settings would be 11, 21, 31, and 41 or 12, 22, 32, and 62. These examples are incorrect because the x1 digits are the same in all enclosure IDs (either 1 or 2). If you do not set the single digit of the enclosure IDs to be unique among enclosures in a redundant drive loop/channel pair, then drive loop/channel errors might be randomly posted in the DS4000 subsystem Major Event Log (MEL), especially in the cases where the DS4300 storage substems are connected to EXP810s and EXP100s. In additon, enclosure IDs with same single digits in a redundant drive loop/channel pair will cause the DS4000 subsystem controller to assign a soft AL_PA address to devices in the redundant drive loop/channel pair. The problem with soft AL_PA addressing is that AL_PA address assignment can change between LIPs. This possibility increases the difficulty of troubleshooting drive loop problems because it is difficult to ascertain whether the same device with a different address or a different device might be causing a problem. 4. If a DS4000 subsystem undergoes any operation that causes the controller to reset and go through the start-of-day boot process while you are attempting to add hardware, drives, or logical drives associated with the controller, the controller will send alert event notifications to the DS4000 subsystem Major Event Log (MEL) Log. The events indicate that the drives or the logical drives are offline or failed. The event notifications in the MEL Log are expected during the time that the controller is going through a boot process. The workaround is to wait at least 10 minutes after the controller reset is complete before moving logical drives or adding hardware. Use the DS4000 subsystem MEL to verify the time of the last controller reset event. 5. In the DS4300 and DS4500 Installation, User's and Maintenance guides, there are references that might mislead the user into thinking that IBM does not support partially-filled storage expansion enclosures or storage subsystems. IBM does support partially-filled storage expansion enclosures or storage subsystems as long as at least two drives are installed in the storage expansion or subsystem enclosures. However, IBM does not support partially-filled storage expansion enclosures or storage subsystems where the empty slots are required to keep the number of hard drives in the redundant drive loop/channel pair not exceeding the maximum of 112 drives per drive loop/channel. This is to prevent inadvertently inserting drives in those slots causing the controller of getting into the state that might result in lost of access to the storage subsystem. 6. In DS4000 storage subsystem configurations with controller firmware 6.15.2x.xx and higher installed, the performance of write intense workloads such as sequential Tape restores to DS4000 Logical drives with large I/O request sizes (e.g. 256kB) is degraded if the DS4000 logical drives are created with small segment sizes such as 8KB or 16KB. The work around is to create the DS4000 logical drives with segment size of 64KB or higher. Limitations with Storage Manager Installer (SMIA) package version 09.16.xx.62 release 1. AIX requires additional APAR's when connecting a DS-4200 to a host: AIX 5.3: IY87372 AIX 5.2: IY87376 AIX 5.1: IY87376_51 The APAR enables DS-4200 recognition. Without these APAR's the DS-4200 will be recognized as a DS-4700. Limitations with Storage Manager Installer (SMIA) package version 09.16.xx.44 release for the DS4000 controller firmware version 6.12.27.xx and 6.16.8x.xx 1. When installing the individual DS4000 host software packages for AIX such as SMclient-AIX-09.16.G5.41.bff on any version of AIX operating system environment, do not use /usr/SMclient as the install directory. The software installer cannot handle the source directory being the same as the target directory and the installation will fail. The workaround is to use another directory such as /tmp. (cmvc 325667). 2. SAN boot (or root boot) is not supported with AIX operating system version 5.1. There is not any SAN boot restrictions with AIX operating system version 5.2 or 5.3. (cmvc 547281). Limitations with Storage Manager Installer (SMIA) package version 09.16.xx.09 release for the DS4000 controller firmware version 6.16.24.xx None Limitations with Storage Manager Installer (SMIA) package version 09.16.xx.08 release for the DS4000 controller firmware version 6.16.24.xx 1. Controller firmware 06.16.xx.xx does not support EXP100 storage expansion enclosures. Do not download it into DS4000 storage subsystems that have EXP100 enclosures attached. After the 06.16.xx.xx controller firmware is activated, the DS4000 storage subsystem will not recognize the drives in EXP100 enclosures, causing loss of data availability to the RAID arrays and logical drives that are defined in those drives. 2. The storage subsystem might not recognize the drives or drive expansion enclosure correctly which results in the displaying of error messages or the inability to perform storage subsystem management operations, such as creating logical drives or arrays or initializing arrays from the storage management software. This behavior could be caused by powering up a DS4000 storage subsystem without any drive expansion enclosures attached and then connecting one or more drive expansion enclosures to the storage subsystem after it completes boot process. The workaround is to make sure that the drive expansion enclosure(s) with at least two drives are connected to the DS4000 storage subsystem before you turn on the storage subsystem power. 3. If cables are disconnected from a host port and then reconnected to a different host port, the AIX host will not be able to access the DS4800 storage subsystem. The AIX operating system requires that the controller retain World Wide Name (WWN) information after a logout, which includes a disconnected cable. This condition can cause two ports to present the same port ID information to the host if the cables are pulled and moved to a different AIX host port. The workaround is to reboot the controllers after the cables are disconnected and moved to different host ports. 4. The host software installer wizard incorrectly displays the required disk space that is needed for the installation of the host software packages (ie. 99M.) The required disk space should be at least 150M. 5. Remove the drive(s) while the storage subsystem is online and then wait until the storage subsystem is going the boot process following a storage subsystem reboot event to reinsert the (new) drive(s) might cause the drives to be marked as failed after the storage subsystem completes the boot process. The workaround is to wait until the storage subsystem is back online before reinserting the drives. If the storage subsystem still does not recognize the drives, reconstruct the drives by using the Advanced -> Recovery -> Reconstruct menu function in the storage subsystem management window. 6. Uninstalling the storage manager host software package might leave the JAVA JRE directory behind. This problem might occur if you uninstall a copy of the SANtricity Storage Manager software that has been upgraded from a previous release. The newer installation package could not delete the JRE directory created with an older installation package. The workaround is to manually delete any directories left behind after uninstalling the software. 7. When creating remote logical drive mirrors through the SMCli script engine in the DS4000 Storage Manager client program, the following error might display during execution, stopping the remote logical drive mirror creation process: Error 173 - The operation cannot complete because the configuration number on the remote storage array is invalid. Some remote logical drive mirrors might have already been created. Rerun only the portion of the script that should be run to finish creating the rest of the remote logical drive mirrors. 8. A JavaScript error might cause the Glossary pop-up window to stay open when the help contents on the storage management software GUI are closed and reopened. Workaround None. This is a SUN JAVA defect. Limitations with SMIA package version 09.15.xx.06 release for the DS4000 controller firmware version 06.12.xx.xx and 06.15.xx.xx 1. The following error message may be encountered under certain conditions when attempting to create a 2 TB LUN using the Create Logical drive wizard in the Subsystem Management window: "Error 4 - The operation cannot complete because of an incorrect parameter in the command sent to the controller." To avoid this error message, you must take certain steps while using the Create Logical Drive wizard to create a 2 TB LUN. Within the Specify Capacity/Name window within the create logical drive wizard, you must not manually specify the numeric value '2' in the New logical drive capacity field in tandem with the "TB" Units designator. If you do this, the Error 4 message will be issued and you will be unable to create the 2 TB LUN. Click on the up or down arrows next to the input field to select the desire capacity instead. When using the arrows, the program will display the correct maximum logical drive capacity value that can be specified for a given capacity unit (TB, GB, or MB). Limitations with SMIA package version 9.19.xx.xx and DS4000 controller firmware version 06.19.19.00 release NONE.

Otherwise it will be recognized as a DS-4700 Limitations with SMIA package version 9.15.xx.xx and DS4000 controller firmware version 06.15.11.00 release 1. Concurrent firmware download (downloading firmware and NVSRAM with IOs) is not supported when upgrading the DS4800 storage subsystem controller firmware or NVSRAM from 06.14.xx.xx version to 06.15.xx.xx version. ALL IOs must be stopped during the upgrading of the DS4800 controller firmware and NVSRAM from 06.14.xx.xx version to version 06.15.xx.xx. Limitations with SMIA package version 9.14.xx.05 and DS4000 controller firmware version 06.14.xx.xx release None Limitations with SMIA package version 9.12.xx.08 and DS4000 controller firmware version 06.12.03.xx release 1. Do not cut and paste the information in the DS4000 Storage Manager online help into the DS4000 Storage Manager script command window or into the text file that will be used as input for the SMcli script engine. Extra space may be inserted in the required parameter names which will cause error(s) during the script command execution. (267873) 2. In the configuration that have both SATA-technology drives (EXP100) and Fibre-Channel technology drives (EXP700/EXP710/DS4100) behind the same DS4000 storage subsystem, do not download drives firmware to both SATA-technology drives and Fibre-Channel(FC) technology drives at the same time. Download the drive firmware to drives of a single drive technology (either SATA or FC) at a time. 3. Currently, IBM does not support Gold key Premium Feature as a chargeable upgrade. The Gold key Premium Feature is enable or disable depending on the DS4000 storage subsystem models. 4. The Asynchronous Remote Mirroring utility, asyncRVMUtil, is not supported. This utility is used to automatically synchronize the logical drives in the Remote Mirroring pairs. Please contact IBM representatives or resellers for the support of this utility in the future. 5. Do not add drive expansion enclosure(s) to the DS4000 storage subsystem drive loops/channels during the ESM firmware download. The ESM firmware download process might fail due to a disconnected FC loop. Either add the drive expansion enclosure(s) before initiating the ESM firmware download or wait until the ESM firmware download is completed before adding additional drive expansion enclosures to the drive loop/channel. (added 2/10/2006) 6. Small Form-factor Pluggable (SFP) hardware that is removed and then reinserted within 10 seconds might not be recognized by the controller. Device polling is done at 10-second intervals. Any device that is removed and replaced within the 10-second window will not be recognized. After removing SFP hardware, ALWAYS wait at least 20 seconds before replacing or reinserting it. (added 2/10/2006) 7. When connected through the DS4000 Storage Manager Agent and mapped volumes using Storage Partitioning on an in-band managed storage subsystem, the following error message might appear after a successful volume-to-LUN mapping operation: Error 62 - The operation cannot complete because the logical unit number (LUN) is already in use. Please enter another LUN. Verify that the volume-to-LUN mapping was created correctly. If it was, this error is erroneous and can be ignored. (added 2/10/2006) 8. After you disable a premium feature, the Disable Premium Feature dialog might go blank and no longer show any other enabled premium features to select. The workaround is to close and then re-open the dialog. (added 2/10/2006) 9. Changing the AIX host cache settings while the storage array is accepting I/O requests can cause I/O errors or loss of access to data. The workaround is to stop all I/O activity to the storage array, and then change the host cache setting. After the host cache settings have been changed, restart I/O activity. (added 2/10/2006) Limitations with Storage Manager version 9.10.xx.05 and DS4000 controller firmware version 06.10.11.xx release 1. Do not update the DS4000 storage subsystem controller firmware to version 06.1x.xx.xx from versions 05.4x.xx.xx or earlier if the EXP700 ESM firmware of the attached EXP700 was not at 9326 or higher. If the EXP700 ESM firmware is earlier than the 9326 versions, the EXP700 enclosure and the installed drives may not be displayed in the DS4000 subsystem management window after the controller firmware is upgraded to 06.1x.xx.xx version. The work around is to update the EXP700 ESM firmware to the version 9326 or higher first before upgrading the controller firmware to version 06.1x.xx.xx. (260160 - 82841) 2. When connecting the EXP100 drive expansion enclosures, one must set the single digit (X1) of the enclosure ID to unique values. This is to prevent the possibility that one of the drives in the EXP100 enclosures be assigned the same ALPA as the DS4000 controller blade under certain DS4000 storage subsystem reboot scenarios. (261188) Limitations with version Storage Manager version 9.10.xx.02 and DS4000 controller firmware version 06.10.06.xx release 1. The DS4000 Copy Service RVM is not supported at this time for the DS4100 and the DS4300 storage subsystem with Standard or Single Controller options. (Note: With the release of the controller firmware version 06.12.16.00 or higher, the DS4100 with standard option is now supported Copy Service Remote Mirroring and VolumeCopy premium features.) 2. In the Storage Manager version 9 client Subsystem Management window, the preferred owner of a defined logical drive can not be changed if the logical drive is not managed by the preferred owner/controller. The Storage Manager client will grey-out (not allowing one to select) the controller that is currently managing the logical drive in the selection list of the new preferred owner/controller. One is allowed to only select the controller that is not managing the logical to be the new preferred owner. There is no work-around. 3. Concurrent firmware download (downloading firmware with IOs) are not supported when upgrading the controller firmware from 05.xx.xx.xx version to 06.1x.xx.xx version. ALL IOs must be stopped during the 06.1x.xx.xx firmware upgrade from a 05.xx.xx.xx version. 4. Do not pull or insert drives during the drive firmware download. In addition, ALL IOs must also be stopped during the drive firmware download. Otherwise, drives may be shown as missing, unavailable or failed. 5. Controller diagnostics will not run in a DS4000 storage subsystem with single controller. 6. When instructed to remove and reinsert or to replace a hard drive, wait at least 70 seconds before inserting either the removed existing drive or the new drive into the drive slot. Then, wait up to 3 minutes for the drive to be spun up, recognized by the DS4000 storage subsystem and displayed in the Subsystem Management window before repeating the process for another hard drive. There is no work-around. Similarly, wait at least 70 seconds before reinserting either the removed existing ESM module or the new ESM module into the empty ESM slot in the EXP drive expansion enclosure. Then, wait up to 3 minutes for the ESM CRU to be recognized by the DS4000 storage subsystem and displayed in the Subsystem Management window before repeating the process for another ESM. There is no work-around. 7. SMdevices program does not return any information if the Access logical drive is not mapped to the AIX host connected to the DS4000 storage server. Map the Access logical drive to the AIX host and retry the command. 8. Dynamic Volume Expansion for AIX 5.3 must have PTF U499974 installed before expanding any file systems. 9. Staged firmware and NVSRAM download function is not available on the DS4400 (machine type 1742) models with firmware 06.1x.00.00 in conjunction with IBM Storage Manager 09.1x.xx.xx. Limitations with Storage Manager version 8.4x.xx.xx (and earlier) and DS4000 controller firmware version 05.4x.xx.xx (and earlier) releases 1. If the ESM firmware is 953A or earlier, no IOs are allowed during the duration that the EXP100 ESMs are being updated with new firmware, including clustering reservation checking IOs. 2. The DS4000 storage subsystem when configured with the DS4000 EXP100 SATA Drive Expansion Unit is currently reporting a higher frequency of informational events such as Destination Driver Events (DDEs) and Fibre Channel link up/down events ... in the DS4000 Controller event log compared to the DS4000 storage subsystem configured with Fibre Channel drives. Slower response times of SATA disk drives compared to Fibre Channel disk drives cause higher I/O retries from the DS4000 storage subsystem controllers, resulting in a greater number of informational events logged. In addition, the number of information events reported in the DS4000 storage subsystem event log will also grow in proportion to the increase in I/Os to the Logical Drives. In all cases, the DS4000 storage subsystem controller will always successfully service the timeout I/O on the subsequent retries. 3. After you replace a controller with a new controller in the single controller models of DS4000 storage subsystems, the premium features become unauthorized and are out of compliance. Any premium features not supported by the firmware of the new controller are unavailable. The work-around is to upgrade the firmware in the new controller to the same level as the removed controller and re-enable the premium features using the key files that you were provided when the premium feature was originally enabled. 4. When migrating drive Customer Replaceable Units (CRUs) from multiple DS4000 storage subsystems into a single destination DS4000 storage servers, all of the drive CRUs from the same DS4000 storage subsystem should be moved as a ‘set’ into the new destination DS4000 storage server. Before moving the next ‘set’ of drive CRUs, ensure that all of the drive CRUs for a single ‘set’ have been moved to the destination DS4000 storage subsystem. If drive CRUs are not moved as a ‘set’ to the destination DS4000 storage subsystems, the newly relocated array may not appear in the Subsystem Management window. 5. Enclosure IDs may be listed incorrectly in the Subsystem Management window, even if the Enclosure ID switch settings appear to be correct. This is because of the physical design and movement of the Enclosure ID switch, it is possible to leave the switch in a “dead zone” between ID numbers, which will return an incorrect Enclosure ID (this value is 0 in most cases) to the storage management software. When setting the Enclosure ID, ensure that the switch has actuated completely and has settled where the value is clearly visible in the viewing window. 6. To download controller firmware, you must select the drive where the firmware is located. If the drive you select does not respond, the File Selection dialog box will revert to the A: drive and display an error message that drive A: is not ready if there are no media in drive A:. 7. When saving the DS4000 storage subsystem event log entries, it may take up to several minutes to save all entries in the event log depending on the DS4000 management workstation resources. However, the DS4000 Storage Manager client GUI will show the completion of the event log saving almost instantly. The work around is to check the file size of the file that the event log entries are saved periodically; if the file size does not change, the event log saving is completed. 8. Do not perform other storage management tasks, such as creating or deleting logical drives, reconstructing arrays, and so on, while downloading the DS4000 storage subsystem controller firmware and DS4000 EXP ESM firmware. It is recommended that you close all storage management sessions (other than the session that you use to upgrade the firmware) to the DS4000 storage subsystem that you plan to update. 1.3 Enhancements ---------------- * The DS4000 Storage Manager version 9.19 host software for AIX operating systems in conjunction with the DS4000 storage subsystem controller firmware 06.19.18.xx provides support for - Support for attaching the DS4000 EXP810 to the DS4300 Standard-Dual Controller models or Turbo models and the DS4500-All Models.

DS4000 STORAGE SUBSYSTEM CONTROLLER FIRMWARE VERSION 06.1X.XX.XX REQUIRES THAT THE FIRMWARE VERSION OF AN ATTACHED EXP700 ENVIRONMENTAL SERVICE MODULE (ESM) BE AT VERSION 9326 OR HIGHER. IF THE EXP700 ESM FIRMWARE IS EARLIER THAN THE 9326 VERSIONS, THE EXP700 ENCLOSURE AND THE INSTALLED DRIVES MAY NOT BE DISPLAYED IN THE DS4000 SUBSYSTEM MANAGEMENT WINDOW AFTER THE CONTROLLER FIRMWARE IS UPGRADED. 2. DS4000 STORAGE SUBSYSTEM CONTROLLER FIRMWARE VERSION 06.1X.XX.XX REQUIRES THAT THE FIRMWARE VERSION OF AN ATTACHED EXP100 ENVIRONMENTAL SERVICE MODULE (ESM) BE AT VERSION 955X OR HIGHER. IT IS NOT POSSIBLE TO UPGRADE EXP100 ESM FIRMWARE VERSIONS THROUGH 953X TO VERSION 955X WHEN THE CONTROLLER FIRMWARE IS AT 06.1X.XX.XX. TO DETERMINE THE FIRMWARE LEVEL OF AN EXP100 ESM, IDENTIFY THE PRODUCT LABEL LOCATED AT THE REAR OF THE EXP100 ENCLOSURE. ONLY LABELS ON WHICH THE FIELD REPLACEABLE UNIT (FRU) PART NUMBER READS 25R0156 POSITIVELY INDICATE THAT AN ESM MODULE IS RUNNING FIRMWARE VERSION 955X OR HIGHER. IF THERE IS NO LABEL OR THE PART NUMBER ON THE LABEL DOES NOT READ 25R0156, THE ESM MAY STILL HAVE THE FIRMWARE VERSION 955X OR HIGHER IF IT HAD BEEN PREVIOUSLY UPGRADED. IF NECESSARY, CONTACT YOUR IBM REPRESENTATIVE, SUPPORT, OR RESELLERS FOR ASSISTANCE. IN ADDITION, IT IS NOT POSSIBLE TO UPGRADE THE ESM FIRMWARE FROM VERSION 953X TO VERSION 956X OR LATER DIRECTLY. THE 953X ESM MUST BE UPGRADED TO VERSION 9554 FIRST BEFORE IT CAN BE UPGRADED TO VERSION 956X. 3. CURRENTLY, THE ONLY DS4000 STORAGE SUBSYSTEMS THAT ARE SUPPORTED BY THE 06.12.XX.XX CONTROLLER FIRMWARE VERSION ARE THE DS4100 - ALL MODELS, THE DS4300 WITH STANDARD (DUAL CONTROLLER) OR TURBO OPTIONS, THE DS4400 AND THE DS4500. DO NOT DOWNLOAD THIS CONTROLLER FIRMWARE ON ANY OTHER DS4000 STORAGE SUBSYSTEM. THERE IS NOT ANY CHECKING FOR THIS RESTRICTION INSIDE THE STORAGE MANAGER CLIENT PROGRAM. 4. The only DS4000 storage subsystems that are supported by the 06.14.xx.xx or higher (06.14.xx.xx, 06.15.xx.xx, 06.16.xx.xx, or 06.19.xx.xx) controller firmware version are the DS4200 (06.16.88.xx or higher), DS4300 Standard-dual controller or Turbo models (06.19.xx.xx or higher), and the DS4500 (06.19.xx.xx or higher), DS4700 (06.16.4x.xx or higher) and DS4800 (06.14.xx.xx or higher) storage subsystems. Currently, there are not any controller firmware packages version 06.14.xx.xx and higher for other DS4000 storage subsystems. Do not download this controller firmware on any other DS4000 storage subsystems. 5. Always check the README files (especially the Dependencies section) that are packaged together with the firmware files for any required minimum firmware level requirements and the firmware download sequence for the DS4000 drive expansion enclosure ESM, the DS4000 storage subsystem controller and the hard drive firmware. 6. If the managed DS4000 storage subsystem had the FC/SATA intermix premium feature enable, do not upgrade the controller firmware from version 06.10.xx.xx to version 06.12.xx.xx until a FC/SATA intermix premium feature key file is generated and available. Once the controller firmware is upgraded to version 06.12.xx.xx, the FC/SATA intermix premium feature will be shown as out-of-compliance and the FC/SATA intermix premium feature key file is required to re-enable the feature. When the FC/SATA intermix premium feature is in out-of- compliance state, LUNs management functions like creations, deletions and modifications will not be operational. Please refer to the FC/SATA intermix premium feature activation card that was shipped with the FC/SATA intermix premium feature kit for instructions to generate the required premium key file. 7. The DS4800 storage subsystems do not support the attachment of the DS4000 EXP700 drive expansion enclosures. The EXP700 enclosure must be upgraded into DS4000 EXP710 enclosure using the DS4000 EXP700 Models 1RU/1RX Switched-ESM Option Upgrade Kit before it can be attached to the DS4800 storage subsystems. 8. THE DS4000 STORAGE SERVER WITH CONTROLER FIRMWARE VERSION 05.41.1X.XX MUST BE UPGRADED TO CONTROLLER FIRMWARE VERSION 05.41.5X.XX FIRST BEFORE IT CAN BE UPGRADED TO CONTROLLER FIRMWARE VERSON 06.1X.XX.XX OR LATER. OTHERWISE, THE ERROR 231-FIRMWARE INCOMPATIBLE WILL BE DISPLAYED. 9. DS4000 storage subsystem controller firmware versions 6.12.16.xx or higher and EXP100 storage expansion enclosure ESM firmware version 9563 or higher are required to provide support for the new 400G SATA drive options and CRUs (P/Ns 39M4570 and 39M4575, respectively) in addition to the new 250G SATA drive CRUs (P/N 40K6837.) This new 250G SATA drive CRU is functionally equivalent to the previously-released CRUs (P/N 90P1349). 10. This version 06.16.xx.xx of the DS4800 controller firmware is not compatible with the EXP100 SATA drive expansion enclosures. DO NOT download it into the DS4800 storage subsystems that have EXP100 drive expansion enclosures attached. After the 06.16.xx.xx controller firmware is activated, the DS4800 storage subsystem will not recognize the drives in EXP100 enclosures, causing loss of data availability to the raid arrays and logical drives that are defined in those drives. The controller firmware version 6.15.xx.xx and earlier must be installed in the DS4000 storage subsystems that have EXP100 SATA drive expansion enclosure attached instead. 11. Controller firmware 06.16.xx.xx is required to support EXP810 storage expansion enclosures. 12. Controller firmware 06.16.4x.xx and higher is required for the DS4700-all models and the DS4800-model 80A/80H. These models do not support older 06.16.xx.xx versions of controller firmware. The attachment of EXP100 enclosures is not supported for these models. 13. Controller firmware 06.16.88.xx and higher is required for the DS4200-all models. These models do not support older 06.16.xx.xx versions of controller firmware. The attachment of EXP100, EXP710 and EXP810 enclosures is not supported for these DS4200 models. 14. The latest fcp.disk.array (RDAC) APAR as stated in the section 1.5 "Level Recommendation and Prerequisites for the update" must be installed after installing the latest devices.fcp.disk.array (RDAC) driver. 15. Controller firmware 06.19.xx.xx is required for the DS4300- standard-dual controller or Turbo models and the DS4500-all models, for attaching the EXP810 storage expansion enclosures. IBM DS4000 Storage Manager version 9.1x host software requires the DS4000 storage subsystem controller firmware be at version 05.30.XX.XX or higher. The only IBM DS4000 Storage Manager version 09.1x.xx.xx for AIX management functions supported on DS4000 storage subsystems with controller firmware version 04.xx.xx.xx up to 05.2x.xx.xx is controller firmware and NVSRAM download. ============================================================================== 2.0 Installation and Setup Instructions ------------------------------------------ The IBM DS4000 System Storage Manager Version 9 Installation and Support Guide for AIX, HP-UX, Solaris and Linux on POWER is also available on IBM's Support web site as a downloadable Portable Document format (PDF) file. This guide along with the DS4000 Storage Manager program Online Help provide the installation and support information. Note: The web-download Storage Manager version 9.19 host software package must be first unpacked (tar -xvz) into a user-defined directory. Then, go to this directory, locate the AIX directory to access the Storage Manager version 9.19 host software installation file(s). ======================================================================= 3.0 Configuration Information and Usage Notes - AIX Platforms --------------------------------------------------------------- * It is important to set the queue depth to a correct size for AIX hosts. Having too large of a queue depth can result in lost file systems and host panics. Please refer to the IBM DS4000 Storage Manager Version 9 for UNIX and AIX Environments Installation and Support Guide for details. * Disabling Cache mirroring while the write-cache is permitted, but not recommended for most environments and applications. Loss of data could occur in the event of a controller failure (data in cache, but not written to disk). Refer to the Installation and Support Guide for further information. * SCSI-3 Persistent Reservation is supported on AIX with DS4000 Storage Systems. * Each AIX host (server) can support 1 or 2 DS4000 Partitions (or Host Groups), each with a maximum of 256 Logical Drives on AIX 5.1, 5.2 and 5.3. * For most applications, AIX host attaches to DS4000 storage subsystems using pairs of Fibre Channel adapters (HBA). For each adapter pair, one HBA must be configured to connect to controller "A" and the other to controller "B". Each HBA pair must be configured to connect to a single partition in a DS4000 storage subsystem or multiple DS4000 storage subsystems (fanout). To attach an AIX host to a single or multiple DS4000 with two partitions, 2 HBA pairs must be used. * SAN Switch Zoning Rules: Each HBA within a host must be configured in a separate zone from other HBAs within that same host, when connected to the same DS4000 controller port. In other words, only 1 HBA within a host can be configured in the same zone with given DS4000 controller port. * For most Direct-attach applications, the connections of DS4000 storage arrays on AIX should be configured with two HBAs for complete path availability. As such, dual-path configurations are restricted to the following: DS4200/DS4700/DS4800 - Up to four servers configurations (2, 4, 6 or 8 HBAs) Each HBA pair must be connected to both A & B host-side controller ports. DS4100/DS4300 - one or two server configurations only (2 or 4 HBAs) Each HBA pair must be connected to both A & B host-side controller ports. DS4400/DS4500 - one or two server configurations only (2 or 4 HBAs) Each HBA pair must be connected to both A & B controllers. Only 1 connection on each host-side mini-hub can be used. * Single HBA configurations are allowed, but each single HBA configuration requires that both controllers in the DS4000 be connected to the host. In a switch environment, both controllers must be connected to the switch within the same SAN zone as the HBA. In a direct-attach configurations, both controllers must be "daisy- chained" together. This can only be done on the DS4400/DS4500 storage servers. * Multiple host attachment to a host-side mini-hub is not supported. * Storage Partitions and the Default Host Group DS4000 offers a premium feature called "Storage Partitioning" which enables users to associate a set of logical drives on a DS4000 Storage Server that can only be accessed by specified hosts and host ports. This association of logical drives to a set of hosts and host ports is called a Storage Partition. The benefit of defining Storage Partitions is to allow controlled access to the logical drives on the DS4000 storage subsystem to only those hosts also defined in the Storage Partition. Without the use of Storage Partitioning, all logical drives appear within what is called the Default Host Group, and they can be accessed by any fibre channel initiator that has access to the DS4000 host port. When homogeneous host servers are directly attached to the DS4000 storage subsystem, access to all logical drives may be satisfactory, or when attached to a SAN, zoning within the fabric can be used to limit access to the DS4000 host ports to specific set of hosts. The DS4300 standard product (without the Turbo feature) provides the Default Host Group. Premium features are available to support four, eight, or sixteen Storage Partitions. If logical drive access control is required for your configuration, particularly in a SAN or multiple server environments, then it is recommended that you add the option for Storage Partitions. On other DS4000 storage subsystems which include a minimum number of Storage Partitions, Storage Partitioning should be used when configuring logical drives and hosts. * Booting from a DS4000 subsystem utilizing SATA drives for the boot image is supported but not recommended due to performance reasons. * Boot images can be located on a volume in DS4000 partitions that have greater than 32 LUNs per partition if utilizing AIX release CD's 5.2 ml-4 (5.2H) and 5.3.0 ml-0 or above. These CD's contain DS4000 drivers that support greater than 32 LUNS per partition. If older CD's are being used the boot image must reside in a partition with 32 LUNS or less. AIX 5.1 needs to retain the boot image on a volume that resided in a partition with less than 32 LUNs. * Dynamic Volume Expansion (DVE) is only supported on AIX 5.2 and 5.3. AIX 5.3 must have PTF U499974 installed before using DVE. * When booting from a DS4000 device, both paths to the boot device must be up and operational. Single HBA configurations are supported, but must have both controllers connected, as described above. * Path fail-over is not supported during the AIX boot process. Once the AIX host has booted, fail-over operates normally. * Interoperability with tape devices is supported on separate HBA and switch zones. * Interoperability with IBM 2105 and SDD Software is supported on separate HBA and switch zones. * Online concurrent firmware and NVSRAM upgrades of FC arrays are only supported when upgrading from 06.10.06.XX to another version of 06.1X.XX.XX. APAR_aix_51 = IY64463 APAR_aix_52 = IY64585 APAR_aix_53 = IY64475 It is highly recommended that Online FW upgrades be scheduled during low I/O loads. Upgrading firmware from 05.xx.xx.xx to version 06.xx.xx.xx must be performed with no IOs. There is no work-around. * When using FlashCopy, the Repository Volume failure policy must be set to "Fail FlashCopy logical drive", which is the default setting. The "Fail writes to base logical drive" policy is not supported on AIX, as data could be lost to the base logical drive. * VolumeCopy must be used in conjunction with Flashcopy. The VolumeCopy source volume must be a FlashCopy copy. Refer to the IBM DS4000 Storage Manager version 9.1x Installation and Support Guides for AIX, HP-UX and Solaris for more information. * AIX Clustering (HACMP, PSSP, GPFS) is now supported with Storage Manager version 9.1x on FC systems. Please see one of the following Configuration Information documents for specific support information. These are located in the "Important notices and readmes" section on the DS4000 support web site. HACMP configuration information for DS4000 on pSeries/AIX Servers PSSP/GPFS configuration information for DS4000 on pSeries/AIX Servers * Do not perform other storage management tasks, such as creating or deleting logical drives, reconstructing arrays, and so on, while downloading the DS4000 storage subsystem controller firmware and DS4000 EXP100 ESM firmware. It is recommended that you close all storage management sessions (other than the session that you use to upgrade the firmware) to the DS4000 storage subsystem that you plan to update. * All enclosures (including DS4000 storage subsystem with internal drive slots) on any given drive loop/channel should have complete unique ID's, especially the single digit (x1) portion of the ID, assigned to them. For example, in a maximum configured DS4500 storage subsystem, enclosures on one redundant drive loop should be assigned with id's 10-17 and enclosures on the second drive loop should be assigned with id's 20-27. Enclosure id's with the same single digit such as 11, 21 and 31 should not be used on the same drive loop/channel. In addition, for enclosures with mechanical enclosure ID switch like DS4300 storage subsystems, EXP100 or EXP710 storage expansion enclosures, do not use enclosure ID value of 0. The reason is with the physical design and movement of the mechanical enclosure ID switch, it is possible to leave the switch in a “dead zone” between ID numbers, which return an incorrect enclosure ID to the storage management software. The most commonly returned enclosure ID is 0 (zero). In addition to causing the subsystem management software to report incorrect enclosure ID, this behavior also result in enclosure ID conflict error with the storage expansion enclosure or DS4000 storage subsystem intentionally set the ID to 0. The DS4200 and DS4700 storage subsystems and the EXP420 and EXP810 storage expansion enclosures did not have mechanical ID switches. Thus, they are not susceptible to this problem. In addition, these storage subsystems and storage expansion enclosures automatically set the Enclosure IDs. IBM recommendation is not make any changes to these settings unless the automatic enclosure ID settings resulting in non- unique single digit settings for enclosures (including the storage subsystems with internal drive slots) in a given drive loop/channel. * If there is previous version (8.x or 9.1x) of the IBM DS4000 Storage Manager host software (ie. SMRuntime, SMClient, RDAC, SMUtil and SMAgent packages) installed in the system, you have to uninstall it first before installing the new version of the storage manager software. Refer to the IBM System Storage™ DS4000 Storage Manager version 9 Installation and Support Guide for AIX, HP-UX, Solaris and Linux on POWER for instructions. 3.1 Helpful Hints ------------------------------- 1. The DS4500 and DS4300 storage subsystem have new recommended drive-side cabling instructions. The DS4500 instructions are documented in the IBM System Storage DS4500 Installation, Users. and Maintenance Guide (GC27-2051-00 or IBM P/N 42D3302). The DS4300 instructions are documented in the IBM System Storage DS4300 Installation, Users. and Maintenance Guide (GC26-7722-02 or IBM P/N 42D3300). Please follow the cabling instructions in these publication to cable the new DS4500 and DS4300 setup. If you have an existing DS4500 setup with four drive side minuhub installed that was cabled according to the previously recommended cabling instructions, please schedule down time as soon as possible to make changes to the drive side FC cabling. Refer to the IBM System Storage DS4500 and DS4300 Installation, Users. and Maintenance Guide for more information. 2. The ideal configuration for SATA drives is one drive in each EXP per array, one logical drive per array and one OS disk partition per logical drive. This configuration minimizes the random head movements that increase stress on the SATA drives. As the number of drive locations to which the heads have to move increases, application performance and drive reliability may be impacted. If more logical drives are configured, but not all of them used simultaneously, some of the randomness can be avoided. SATA drives are best used for long sequential reads and writes. 3. IBM recommends at least one hot spare per EXP100 drive expansion enclosure. A total of 15 hot-spares can be defined per DS4000 storage subsystem configuration 4. If you are unable to see the maximum number of drives during Automatic Configuration, you should be able to use Manual Configuration to select individual drives and select the maximum number of drives allowed. 5. The DS4000 controller host ports or the Fibre Channel HBA ports can not be connected to a Cisco FC switch ports with "trunking" enable. You might encounter failover and failback problems if you do not change the Cisco FC switch port to "non-trunking" using the following procedure: a. Launch the Cicso FC switch Device Manager GUI. b. Select one or more ports by a single click. c. Right click the port(s) and select Configure, a new window pops up d. Select the "Trunk Config" tab from this window, a new window opens e. In this window under Admin, select the "non-trunk" radio button, it is set to auto by default. f. Refresh the entire fabric. 6. Serial connections to the DS4000 storage controller must be set to a baud rate of either 38200 or 57600. Do not make any connections to the DS4000 storage subsystem serial ports unless it is instructed by IBM Support. Incorrect use of the serial port might result in lost of configuration, and possibly, data. 7. Starting with the DS4000 Storage Manager (SM) host software version 9.12 or later, the Storage Manager client script window looks for the files with the file type of ".script" as the possible script command files. In the previous versions of the DS4000 Storage Manager host software, the script window looks for the file type ".scr" instead. (i.e. enableAVT.script for SM 9.12 or later vs. enableAVT.scr for pre-SM 9.12) 3.2 Configuration settings ------------------------------ 1. By default the IBM DS4000 Storage Manager 9.1x firmware does not automatically map logical drives. This means that the logical drives are not automatically presented to host systems. a. For a new installation, after creating new arrays and logical drives, create a storage partition with the host type of AIX and map the logical drives to this partition or change the default host type to AIX if the Storage Partitioning premium feature is not enable. b. If you are upgrading the NVSRAM with Storage Partitions, you may have to change the default host type to match the host system OS. After upgrading the NVSRAM, the default host type is reset to Windows 2000/Server 2003 non-clustered for DS4000 storage server with controller firmware version 06.14.xx.xx or later. For DS4000 storage server with controller firmware version 06.12.xx.xx or earlier, it is reset to Windows non-clustered (SP5 or higher), instead. Refer to the IBM DS4000 Storage Manager online help to learn more about creating storage partitions and changing host types. ======================================================================= 4.0 Unattended Mode ------------------------ N/A ======================================================================= 5.0 WEB Sites and Support Phone Number -------------------------------------------------------------- 5.1 IBM System Storage™ Disk Storage Systems Technical Support web site: http://www.ibm.com/servers/storage/support/disk/ 5.2 IBM System Storage™ Marketing Web Site: http://www.ibm.com/servers/storage/disk 5.3 You can receive hardware service through IBM Services or through your IBM reseller, if your reseller is authorized by IBM to provide warranty service.
