In the DS4000 Storage Manager 9.1 Client, Storage Partitioning must be enabled with the host type of 'Linux' selected and the UTM must be removed from the 'Linux' storage partition when the IBM FC HBA failover Linux device driver is used as multipathing (failover/ failback) driver. Otherwise the correct drive information is not presented to the Linux operating system. Note: When using the Linux RDAC as the multipathing driver, the "LNXCL" host type must be used and there is not a requirement that the UTM(Access LUN) must be removed from the LNXCL Storage Partitioning partition. 2. When updating Firmware or NVSRAM with high disk activity a controller may become unresponsive during the update. IBM recommends that disk I/O be stopped during these code updates. 3. Storage Manager prompts you for a password if all hard disk drives are removed from the storage subsystem. After removing all drives from a storage subsystem (or powering on the controller only without any drive expansion enclosures), the IBM DS4000 Storage Manager software will prompt you for a password when trying to start the software or trying to perform protected operations. Any password entered will fail. Password information is stored on a reserved area of each hard disk drive on the storage subsystem. Each drive stores a mirrored copy of the password data. When there are no drives in the storage subsystem, the storage management software does not find the password data when you attempt password protected operations. Add one drive to the storage subsystem and retry the operation. Since the RAID controller unit should not be powered on until the expansion units are attached and powered on, this should be done by powering off the RAID controller unit, properly attaching all expansion units (with drives installed), to the RAID controller unit and powering them on, and then powering the RAID controller unit back on. At this point the storage subsystems can be re-discovered and managed using the IBM DS4000 Storage Manager 8.3 software. 4. The DS4000 Storage Management dialog windows may be displayed cropped without the vertical and horizontal scroll bars. Just move the mouse pointer over the edge of the window until the mouse pointer change to window resize pointer, left click and hold to grip the window edge to resize it. 5. The IBM FAStT500, DS4400 or DS4500 Storage Server hardware and software is designed to have redundant paths from the host system to ensure the availability of storage. However, it is possible to connect a single host adapter from the host system to one of the controller minihubs and then connect this minihub to the minihub of the other controller. This configuration will create a FC-AL loop between the host adapter and the two IBM FAStT500, DS4400 or DS4500 Storage Server controllers and no redundant path to the host system. When you connect the two minihubs together, always connect the "IN" port of one minihub to the "OUT" port of the other minihub or vice versa. Do not connect the "IN" port of one to the "IN" port of the other minihub or the "OUT" port of one minihub to the "OUT" port of the other minihub. 6. When creating a Remote Mirror of a base logical drive, in the case where a FlashCopy of the base logical drive has already been created, the following restriction applies. If the Remote Mirror relationship is created while the base logical drive is receiving I/O, the FlashCopy logical drive will be failed. The work around is to quiesce I/O to the base logical drive while you are creating the remote mirror relationship. Alternatively, if the Remote Mirror relationship is created before creating the FlashCopy logical drive, the FlashCopy logical drive will not be failed. 7. Dynamically changing the cache read ahead multiplier setting via the storage manager client may result in an error message indicating the operation has failed. Despite the error message, the request to change the cache read ahead multiplier will remain queued to the controllers and will eventually complete when I/O activity to the storage subsystem has subsided. In order to avoid the error message and any delays in the cache read ahead multiplier value changing, it is recommended to change the cache read ahead multiplier when the subsystem is in a quiesced state. 8. This following behavior applies for the direct Fibre Channel connection setup between the DS4300 storage server host ports and the server HBA ports only. If all DS4300 host ports are occupied, the DS4300 event log may show "host-side data rate negotiation failed" error when the server is booted up, this is normal error that were generated during the host rate negotiation routine inside the DS4300 storage server. 9. When managing the DS4000 Storage Servers with firmware version 05.3x.xx.xx, the Help window of the Subsystem Management window may not be displayed correctly the topics that are listed as result of executing a full text search. 10. The DS4000 storage server 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 FibreChannel link up/down events ... in the DS4000 Controller event log compared to the DS4000 strorage server 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 server controllers, resulting in a greater number of informational events logged. In addition, the number of information events reported in the DS4000 storage server event log will also grow in proportion to the increase in I/Os to the Logical Drives. In all cases, the DS4000 storage server controller will always successfully service the timeout I/O on the subsequent retries. 11. When migrating array(s) from a dual controller DS4000 storage server to a single controller DS4000 storage server, you must first set the preferred owner of the to-be-migrated array(s) to be controller A before inserting it into the drive slots of a single controller DS4000 storage server. Otherwise, the array(s) will not be added to the single controller DS4000 storage server correctly which might cause problems. 12. When managing a single controller DS4000 Storage Server model, do not use the menu option - Configuration->Automatic... - in the Subsystem Management window to create LUNs. You might not be able to access or manage LUNs that are created this way. 13. After you replace a controller with a new controller in the single controller models of DS4000 storage servers, 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. 14. When you migrating drive Customer Replaceable Units (CRUs) from multiple DS4000 storage servers into a single destination DS4000 storage servers, all of the drive CRUs from the same DS4000 storage server 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 server. If drive CRUs are not moved as a ‘set’ to the destination DS4000 storage servers, the newly relocated array may not appear in the Subsystem Management window. 15. 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. 16. 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:. 17. You must suspend all I/O while ESM firmware downloads if you select multiple enclosures for downloading ESM firmware. If you select only one enclosure for download at a time, you can download ESM firmware with I/Os. However, IBM recommends that you suspend all I/O activity to perform firmware upgrades. 18. If the EXP100 ESM firmware version is 953x or earlier, no IOs are allowed during the duration that the EXP100 ESMs are being updated with new firmware, including clustering reservation checking IOs. 19. When saving the DS4000 storage server 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. 20. Do not perform other storage management tasks, such as creating or deleting logical drives, reconstructing arrays, and so on, while downloading the DS4000 storage server 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 server that you plan to update. 21. Inter-operability with tape devices is supported on separate HBA and switch zones. New limitations with Storage Manager version 9.10.xx.02 and DS4000 controller firmware version 06.10.06.xx release 22. The DS4000 Copy Service RVM is not supported at this time for DS4300 Base and Single Controller storage servers models. 23. 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 currrently managing the logical drive in the selection list of the new preferred owner/comntroller. 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. 24. Concurrent firmware download (downloading firmware/NVSRAM to the DS4000 storage server controllers with IOs to the host servers) is not supported when upgrading the controller firmware from a 05.xx.xx.xx version to a 06.10.xx.xx version. ALL IOs must be stopped during the version 06.10.xx.xx controller firmware upgrade from a pre- 06.10.xx.xx version. 25. Do not pull or inserting 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. 26. Controller diagnostics will not run in a DS4000 storage server with single controller. 27. When instructing 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. 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. There is no work-around. 28. 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." 29. The transmission of the User Datagram Protocol (UDP) broadcast message that starts auto discovery may be blocked because of a configuration issue. The storage management software uses UDP at the broadcast IP address 255.255.255.255. The system must be configured to allow broadcast messages for auto discovery to work. The work-around is to manually add storage arrays via their IP address or host name or add the following command to enable the broadcast address on that Ethernet port and allow normal auto discovery to procee. For example, route add -host 255.255.255.255 eth0 30. The DS4000 Storage Manager client crashes on Linux, AMD-based, 64-bit server because support for the “no execute” bit is enabled by default. To fix the problem, one need to disable support for the "no execute" bit in the operating system by editing the /etc/grub.conf file (if you are using GRUB to boot), and add the following parameter to the end of the kernel line: noexec=off For example, in Red Hat Enterprise Linux AS, you would add noexec=off to the end of the kernel line in the grub.conf file as shown here: kernel /boot/vmlinuz-2.4.21-15.ELsmp ro root=LABEL=/ hdc=ide-scsi noexec=off After adding this information, reboot the server. New limitations with Storage Manager version 9.10.xx.05 and DS4000 controller firmware version 06.10.11.xx release 31. Do not update the DS4000 storage server 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. 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 workaround is to update the EXP700 ESM firmware to the 9326 version first before upgrading the controller firmware to version 06.1x.xx.xx. (260160 - pr 82841) 32. When connecting the EXP100 enclosures, one must set the single digit (X1) of the enclosure ID to unique values. This is to prevent the possiblity that the controller blade has the same ALPA as one of the drives in the EXP100 enclosures under certain DS4000 controller reboot scenarios. (261188) 33. There are not DS4000 Storage Manager version 9.1 Linux host software packages for AMD-64 or EM64T servers running Linux OS kernels written in native AMD-64 or EM64T code. Please contact IBM resellers or representatives for availability of such support in the future. 34. In Redhat EL 3.0 Update 3 environment, when there are memory intensive applications running, RHEL 3.0 kernel may not process the memory request from the running device driver processes like network driver or Linux RDAC driver. In certain case, this denial of memory request to the RDAC driver cause it to loop in the memory request routine indefintely. In that case, the /var/log/messages will be full with the messages like the ones shown below kernel: 493 [RAIDarray.mpp] Cmnd failed-retry 0:0:0 the same path vSCp SN 13633729 TOLO pcmnd SN HOCOTOLO or kernel: 494 [RAIDarray.mpp] Cmnd-failed try alt ctrl 0 vcmnd SN 13799399 TOLO pcmnd SN H1COTOLO The recovery procedure is to reboot the server. (261523) ======================================================================= 1.3 Enhancements --------------------------- ATTENTION: New features that are introduced with the DS4000 Storage Manager version 9.1 host software will not be available for any DS4000 storage server controllers without the controller firmware version 06.10.xx.xx installed. The DS4000 Storage server controller firmware version 6.10.xx.xx is available for the following DS4000 Storage server only - DS4300 Turbo option, DS4400 and DS4500. Please contact your IBM service representative or IBM resellers for availability of additional DS4000 Storage server models support with controller firmware version 6.10.xx in the future.

(also see Dependencies section) ======================================================================= 1.5 Dependencies -------------------------- ATTENTION: 1. DS4000 STORAGE SERVER CONTROLLER FIRMWARE VERSION 06.10.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. 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 RESELLER FOR ASSISTANCE. 2. DS4000 STORAGE SERVER CONTROLLER FIRMWARE VERSION 06.10.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. 3. CURRENTLY, THE ONLY DS4000 STORAGE SERVERS THAT ARE SUPPORTED BY THE 06.1X.XX.XX CONTROLLER FIRMWARE VERSION ARE THE DS4300 WITH TURBO OPTION, THE DS4400 AND THE DS4500. DO NOT DOWNLOAD THIS CONTROLLER FIRMWARE ON ANY OTHER DS4000 STORAGE SERVER. THERE IS NOT ANY CHECKING FOR THIS RESTRICTION INSIDE THE STORAGE MANAGER CLIENT PROGRAM. 4.

At this time, the supported drivers are as follows: 1. IBM DS4000 Host Adapter device driver version 7.01.01-fo (failover version) and 7.01.01 (non-failover) for Linux 2. IBM DS4000 FC-2 and FC2-133 Host Bus Adapter device driver version 7.01.01-fo (failover version) and 7.01.01 (non-failover) for Linux 3. IBM FAStT_MSJ 2.0.29 build 39 4. IBM DS4000 Storage Server Linux RDAC version 09.00.A5.01 ======================================================================= 3.3 Helpful Hints ----------------------- 1. 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. 2. Depending on the storage subsystem that you have purchased, you may have to purchase the DS4000 storage partitioning premium feature option or an option to upgrade the number of supported partitions in a storage subsystem. Please see IBM Marketing representatives or IBM resellers for more information. - IBM DS4100 storage subsystem (machine type 1724): The standard configuration does not have the DS4000 storage partitioning premium enabled. Four partition, eight partition, sixteen and an upgrade from four to eight partition storage partitioning premium feature options can be purchased. - IBM DS4300 storage subsystem (machine type 1722): The standard configuration does not have the DS4000 storage partitioning premium enabled. Four partition, eight partition, sixteen and an upgrade from four to eight partition storage partitioning premium feature options can be purchased. The IBM DS4300 Turbo option comes with 8 partition storage partitioning premium option installed. An upgrade to 64 partitions can be purchased for the IBM DS4300 Turbo option. - IBM FAStT200 (machine type 3542: The standard configuration has 16 partition storage partitioning premium option installed. No additional storage partitioning premium feature options can be purchased for these storage subsystems. - IBM FAStT500 and DS4400 storage subsystems (machine type 3552 and 1742 - models 1RU and 1RX, respectively): The standard configuration has 64 partition storage partitioning premium option installed. No additional storage partitioning premium feature options can be purchased for these storage subsystems. - IBM DS4500 storage subsystem (machine type 1742 - models 90X and 90U): The standard configuration has 16 partition storage partitioning premium option installed. An upgrade from 16 to 64 partition storage partitioning premium feature option can be purchased. 3. Do not delete the Access LUN or Access Volume if you want to manage the DS4000 storage server in-band (host-agent managed). The Access LUN is required by the SMClient to communicate with the storage controllers when using the in-band management method. 4. 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. 5. When making serial connections to the DS4000 storage controller, the baud rate is recommended to be set at either 38200 or 57600. Note: Do not make any connections to the DS4000 storage server serial ports unless it is instructed by IBM Support. Incorrect use of the serial port might result in lost of configuration, and possibly, data. 6. Fabric topology zoning requirement. To avoid possible problem at the host level, it is best practice that all Fibre Channel (FC) Switches must be zoned such that a single FC host bus adapter can only access one controller per storage array. In addition, this zoning requirement also ensures the maximum number of host connections can be seen and log into the controller FC host port. This is because if a FC HBA port is seen by both controller A and B host ports, it will be counted as two host connections to the storage subsystem - one for controller A port and one for controller B port. Note: The DS4000 Storage Subsystem DS4500, DS4400 and FAStT500 (IBM machine type 1742 and 3552) have two ports per controller - one per minihub slot. The DS4000 Storage DS4300 (IBM machine type 1722) has two ports per controller. The DS4000 storage Subsystem FAStT200 (IBM machine type 3542) has only one port per controller. ======================================================================= 4.0 Configuration Information ---------------------------------------- 4.1 Configuration Settings ------------------------------------ 1. When using the Linux RDAC as the failover/failback driver, the host type should be set to LNXCL instead of Linux. If Linux RDAC is not used, the host type of Linux must be used instead. 2. By default, the IBM DS4000 Storage Manager 9.1 firmware does not automatically map logical drives when the IBM DS4000 storage partitioning premium feature is enabled. This means that the logical drives after being created are not automatically presented to the host systems. a. For a new installation, after creating new arrays and logical drives, if your host OS type is any of the supported version of Linux OS's, create a partition with the host type of Linux and map the logical drives to this partition. b. If you are upgrading with Storage Partitions and the host system OS was other than Microsoft Windows NT is accessing the default host group, you will need to change the default host type. After upgrading, the default host type is reset to Windows non-clustered (SP5 or higher). Refer to the IBM DS4000 Storage Manager online help to learn more about creating storage partitions and changing host types. 3. When you are configuring IBM machine type 1722, 1724, 1742, 3542, or 3552 storage controllers as boot devices, contact IBM support for supported configurations and instructions for configuring IBM storage controllers as boot devices. 4. Running script files for specific configurations. Apply the appropriate scripts to your subsystem based on the instructions you have read in the publications or any instructions in the operating system readme file. A description of each script is shown below. - SameWWN.scr: Setup RAID controllers to have the same World Wide Names. The World Wide Names (node) will be the same for each controller pair. The NVSRAM default sets the RAID controllers to have the same World Wide Names. - DifferentWWN.scr: Setup RAID controllers to have different World Wide Names. The World Wide Names (node) will be different for each controller pair. The NVSRAM default sets the RAID controllers to have the same World Wide Names. - EnableDriveMigration.scr: The Enable drive migration script scans the drives for configurations when they are added to a storage system and will also attempt to use configurations found on the newly added drives. The NVSRAM default will enable drive migration. - DisableDriveMigration.scr: The disable drive migration script allows the addition of disk drives while the system is running. In addition, it identifies the drives as unused capacity regardless of past drive configuration. The NVSRAM default will enable drive migration. - EnableAVT_Linux.scr: The script will enable automatic logical drive transfer (ADT) for the Linux heterogenous host region. Do not use this script unless it is specifically mentioned in the applicable instructions. (This script can be used for other host type if modifications are made in the script, replacing the Linux host type with the appropriate host type that needs to have AVT/ADT enabled) - DisableAVT_Linux.scr: The script will disable the automatic logical drive transfer (ADT) for the Linux heterogenous host region. Do not use this script unless it is specifically mentioned in the applicable instructions. (This script can be used for other host type if modifications are made in the script, replacing the Linux host type with the appropriate host type that needs to have AVT/ADT disabled) 5. When you are configuring IBM machine type 1742 or 3552 storage controllers in clustered Remote Mirror configurations, contact IBM support for supported cluster configurations and instructions for configuring IBM storage controllers in clustered Remote Mirror configurations. ======================================================================= 4.2 Hardware status and information -------------------------------------------------- New installations for IBM Machine types 1722, 1742, 3542,and 3552 should be installed with the IBM DS4000 and FC-2/FC2-133 Host Adapter. The device driver version should be 7.01.01 for DS4000 and FC-2/FC2- 133 Host Adapters.
