The linux directory contains the files necessary to install the IBM FAStT Storage Manager Software version for Linux. The IBM FAStT Storage Manager version 8.21 Installation and Support Guide is also available on the IBM TotalStorage™ Disk Storage Systems Technical Support web site as a downloadable Portable Document Format (PDF) file. The latest Firmware and NVSRAM files for IBM machine types 1742, 3542 and 3552 are available on IBM's Support Web Site. ======================================================================= 1.2 Limitations --------------------- 1. In the Storage Manager 8.21 Client, Storage Partitioning must be enabled with the host type of 'linux' selected and the UTM must be removed from the 'Linux' storage partition. Otherwise the correct drive information is not presented to the Linux operating system. 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. Upgrading FAStT500 with 512MB Cache. If you are upgrading controller firmware on a FAStT500 (machine type 3552) with 512MB of cache, you will need to stop I/O and reboot the controller before upgrading firmware followed by NVSRAM. To determine Storage Controller cache level, perform the following: a. On a storage management station start the client software and select a storage subsystem. b. Select Tools -> Manage Device to open the Subsystem Management Window. c. Highlight the Storage Subsystem that you are upgrading and then select Storage Subsystem -> Profile. It may take a little time for it to create the Storage Subsystem profile. d. Under the Controllers heading is an entry that displays information similar to the following example: Cache/processor size (MB): 256/32 If this setting is listed as 512/32 you will need to arrange to perform this upgrade procedure at a time that you can stop I/O to the Storage Subsystem in order to ensure a successful firmware download and installation. 4. 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 not powering on drives and only the controller), the IBM FAStT 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. 5. Display issues when using 256 color settings. A brownish hash pattern is displayed on the windows and in online help when running in 256 color mode. Run the Storage Manager 8 application in a higher display mode. 6. The FAStT 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. 7. If you get "Error 21 - The Operation cannot complete because a ... is in progress" error when you issue a Subsystem Management command from the IBM FAStT Storage Manager Client, the command may be cached. If the command is cached, the IBM FAStT Storage Manager Client will run the command as soon as the controller resources are available. Wait for at least ten minutes and check to see whether the command has been run. If not, re-attempt the command. 8. If the controller in the IBM FAStT Storage Server with firmware 05.2x.xx.xx is connected to a SAN with more than 64 Host ports that can log into the controllers, one must either use the switch zoning function or rearrange the SAN connections so that only the maximum number of host ports that can be seen and log into the controller is 64. 9. If you define a large number of arrays, you will not be able to right-click a logical drive and get a pop-up menu in the Physical View of the Subsystem management window. You must use the Logical Drive pull-down menu to select the logical drive options. 10. The IBM FAStT 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 FAStT 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. 11. When using the IBM FAStT Storage Manager 8.21 Remote Mirroring Premium Feature. The maximum number of logical drives supported is reduced to 256 Logical Drives for Machine Type 1742 and 16 mirrors and 128 Logical Drives and 8 mirrors for Machine Type 3552. Remote Mirroring is not supported on the machine type 3542. 12. The help button in the IBM FAStT Storage Manager 8.21 "Create a Flashcopy Logical Drive Wizard" does not work. The workaround is to search for Flashcopy in the Enterprise Management Window online help. 13. When creating a Remote Mirror of a base volume the following restriction applies. First, you have created a snapshot of a base volume and the base volume is receiving I/O. Second, you decide to create a mirror relationship, using the base volume as the primary volume in the mirrored pair. As you create the mirror relationship, the snapshot volume is failed. The workaround is to quiesce I/O to the base volume while you are creating the mirror relationship. Alternatively, if the mirror relationship is created before creating the snapshot volume, this will not happen. 14. When one clicks the OK button in the Locate Drive Channel window to stop Locating the Drive Enclosures on a given drive channel, the blue LEDs in all of the drive enclosures in the located drive channel change from "blinking" to solid "ON" state. To turn off the blue LED, one must locate each drive enclosure using the Locate Enclosure button in Drive Enclosure Component window. When the "OK" button is click to stop locating drive enclosure, the blue LED for that drive enclosure is turned off. To open the Drive Enclosure Component window for a drive enclosure, click the Drive Enclosure Component button in its drive enclosure window frame in the 15. The IBM TotalStorage EXP700 drive enclosure blue locator LED is not supported when the EXP700 was connected to the FAStT200 storage subsystem. ======================================================================= 1.3 Enhancements --------------------------- N/A ======================================================================= 1.4 Prerequisites ------------------------ The following vendor kernels listed below have been tested and are required for proper support.

Install and update the driver for the IBM FAStT Host Adapter. a. Install the hardware by using the instructions that come with the adapter. b. Install the IBM FAStT Host Adapter driver by using the instructions provided in the readme file located in the Host_Adapter directory on the installation CD or downloaded with the device driver source package from the IBM support website. 2. Install the new Storage Manager version 8.21 software. Refer to the IBM FAStT Storage Manager version 8.21 for Linux Installation and Support Guide for detailed installation instructions. ======================================================================= 3.2 Refer to the Host_Adapter directory on the installation CD for the applicable drivers or refer to the IBM Support Web Site for the latest supported host adapters, device drivers, and updated readme. At this time, the supported drivers are as follows: 1. IBM FAStT Host Adapter device driver version 6.0-fo for Linux 2. IBM FAStT FC-2 and FC2-133 Host Bus Adapter device driver version 6.0-fo for Linux ======================================================================= 3.3 Helpful Hints ----------------------- 1. The IBM FAStT Storage Manager will prompt you for a password if an attempt is made to manage a storage subsystem where the FAStT RAID Controller Unit does not have access to any hard disk drives. This will occur even if no password has been setup. The automatic discovery will discover each storage subsystem as two separate storage subsystems. To prevent this from occurring, ensure that at least one FAStT EXP500 Expansion Unit with at least one drive is properly attached to the FAStT500 RAID Controller Unit in each storage subsystem that is being managed. 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 FAStT Storage Manager 8.21 software. 2. 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. ======================================================================= 4.0 Configuration Information ---------------------------------------- 4.1 Configuration Settings ------------------------------------ 1. By default the IBM FAStT Storage Manager 8.21 firmware does not automatically map logical drives. This means that the logical drives are not automatically presented to host systems. For a new installation, after creating new arrays and logical drives; a. If your host type is RedHat, create a partition with your host type of Linux and map the logical drives to this partition. b. If upgrading with Storage Partitions and an operating system other than 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 NT. Refer to the IBM FAStT Storage Manager online help to learn more about creating storage partitions and changing host types. 2. When you are configuring IBM machine type 1742, 3542 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 3542, 1742 and 3552 should be installed with the IBM FAStT Host Adapter and Device Driver version 6.0-fo. For more information, refer to the IBM TotalStorage™ Disk Storage Systems Technical Support web site. ======================================================================= 4.3 Unsupported configurations -------------------------------------------- The following lists configurations that are currently not being supported with IBM FAStT Storage Manager 8.21. 1.
