In addition, the EXP500 can only be intermixed with EXP700 if the fibre channel speed of the EXP700 and the DS4000 subsystem drive loop is set to 1Gbps. ======================================================================= 1.2 Limitations --------------------- IMPORTANT: The listed limitations are cumulative. 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 09.60.xx.05 release. None New limitations with Storage Manager Installer (SMIA) package version 09.60.xx.03 release. 1. CMVC 394913 - 131733 Storage Manager 9.60.x5.03 Installer does not import previous configuration used in the Enterprise Management Window when upgrading the Storage Manager host software versions 9.23.xx.xx to 9.60.xx.03. This limitation is fixed in SMIA installer package version 09.60.x5.05 for Linux. 2. DS4000 Controller Firmware supported for I/O attach are 6.12 and 6.60 for RHEL5 and SLES10SP1 Host Operating Systems. 3. Qlogic Multipath failover Drivers are not supported. 4. In-Band Management from Storage Manager on RHEL5 is currently not supported. ======================================================================= 1.3 Enhancements --------------------------- The DS4000 Storage Manager version 9.60 host software for 32bit(IA32/x64) and 64bit(IA64) Linux operating systems in conjunction with the DS4000 storage subsystem controller firmware 06.60.xx.xx provides support for - Initial support for RHEL5 and SLES10 SP1. - Recreate multiple snapshots. SYMbol addition of a re-create snapshot command that will accept a list of snapshots as input. This command will be used by VSS and SMI-S providers to reduce the time needed to re-create several snapshots at one time. - The management of the IBM System Storage DS3300 with controller firmware version 6.50.xx.xx installed. - Support for DS4000 Controller Firmware 6.60.xx.xx. In addition, it also provide - Support for the new Daylight saving time as required by the enactment of the United State's Energy Policy Act of 2005. The Daylight Saving Time (DST) will begin at 2 a.m. on the second Sunday in March and end at 2 a.m. on the first Sunday of November instead of 2 a.m. on the first Sunday of April to 2 a.m. on the last Sunday of October. For the year of 2007, DST will start on March 11, 2007 and end on November 11, 2007. DS4000 storage subsystem users in countries implementing the new DST rules (which includes U.S., Canada, Bermuda) are recommended to upgrade to Storage Manager version 9.19.xx.12 or later before March 2007. Storage Manager version 9.19.xx.12 or later release includes revised DST transition dates to comply with provision of the Energy Policy Act of 2005 extension of Daylight Saving Time (DST) by four weeks, beginning in 2007. There are no data integrity or functional problems caused by an incorrect clock setting. From the DS4000 controller firmware standpoint, this change will have no impact. The software changes are in the Java Runtime software included with the Storage Manager host software. The DS4000 controller uses an internal time clock which is GMT time based. The Storage Manager client software will make the appropriate time changes for reporting the Major Event Log entries (MEL), subsystem information or subsystem configuration changes in the time zone that the management station is installed. If no updates are made to existing DS4000 Storage Manager host software. The primary impact is that Email alerts and Major Event Log (MEL) entries will be off by 1 hour for 3 weeks in the Spring and 1 week in the Fall because they will be translated improperly by the Java Runtime Engine that is currently in use. This is a cosmetic impact only; as noted above, all times within the DS4000 controller firmware are stored in GMT time. Such values will be incorrect for the three-week period but then will be correct later when viewed from DS4000 Storage Manager client software. Additional incorrect timestamps may be seen in diagnostic reports, various subsystem component information displayed in dialog boxes, and performance monitor. In addition to updating the DS4000 Storage Manager host software, additional operating systems patches may be needed for the host server/management station that the DS4000 Storage Manager host software is installed. This will ensure that no problems occur with the implementation of the new DST rule. Please refer to the support web site for your operating systems for more information. Various impact scenarios are described below: Host System DS4000 Impact Operating Storage System Manager No Update No Update The System and DS4000 Controller time stamps are in sync until March 11, to April 1, when the times are 1 hour earlier than the time in the areas where the change is effective. Updated No Update The system and DS4000 controller time stamps will be out of sync by 1:00 hour. For example, a MEL event at 3:00 p.m. on the system will be reported as 2:00 p.m. on the DS4000 MEL logs Not Updated Updated Same as above, except the DS4000 Storage Manager will report with the correct DST time. Updated Updated Best scenario. Everything reports the correct time Please refer to the New Features section of the IBM DS4000 Storage Manager version 9 Installation and Support Guide for Windows 2000/Server 2003, Netware, ESX Server, and Linux for additional information about the IBM DS4000 Storage Manager version 9 enhancements. ======================================================================= 1.4 Level Recommendation and Prerequisites for the update ----------------------------------------------------------- Note: The IBM Storage Manager host software version 9.60 for 32-bit (IA32) and 64-bit (IA64 and x86_64) for RHEL5 and SLES10 SP1 Linux OS new features and changes are described in the corresponding Change History document.

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, 06.19.xx.xx, 6.23.xx.xx, or 6.60.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 DS4700 and 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 DS4700 and DS4800 storage subsystems. 8. THE DS4000 STORAGE SERVER WITH CONTROLLER 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 VERSION 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. The version 06.16.xx.xx of the DS4700 or 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. IBM recommends installing the controller firmware version 6.23.xx.xx and higher in the DS4000 storage subsystems that have EXP100 SATA drive expansion enclosure attached instead. 11. Controller firmware 06.16.xx.xx or higher 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 ONLY supported for these models only if the controller firmware is upgraded to version 6.23.xx.xx or higher. 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. Controller firmware 06.19.xx.xx and higher is required for the DS4300- standard-dual controller or Turbo models and the DS4500-all models for attaching the EXP810 storage expansion enclosures. 15. Controller firmware 06.23.xx.xx and higher is required for the DS4700- all models and the DS4800-all models for attaching EXP810, EXP710 and EXP100 together behind a DS4000 storage subsystem. The intermix of EXP810 and EXP100 behind a DS4700 or DS4800 is supported only with controller firmware version 6.23.xx.xx and higher. IBM DS4000 Storage Manager version 9.60 provides full management support for DS4000 storage subsystems that have controller firmware version 04.01.xx.xx or higher. The only IBM DS4000 Storage Manager version 09.60.xx.xx management function supported on DS4000 storage subsystems with controller firmware version 04.xx.xx.xx up to 04.00.02.xx is controller firmware and NVSRAM download. ======================================================================= 2.0 Installation and Setup Instructions ---------------------------------------------------- Note: The web-download Storage Manager version 9.60 host software package must be first unpacked (tar -xvz) into a user-defined directory.

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. 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. 3. 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 DS4200 storage subsystem (machine type 1814): Depending on the ordering channels, the DS420 storage subsystem is either shipped with 2 storage partitions or with a user selected 2, 4, 8, 16 or 64 storage partitions. If the DS4200 storage subsystem is ordered with less than 64 partitions, various storage partition feature upgrade options can be purchased to increase the maximum number of supported storage partitions. - 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. - IBM DS4700 storage subsystem (machine type 1814): Depending on the ordering channels, the DS4700-model 70 storage subsystem is either shipped with 2 storage partitions or with a user selected 2, 4, 8, 16 or 64 storage partitions. Similarly, the DS4700-model 72 storage subsystem is either shipped with 8 storage partitions or with a user selected 8, 16 or 64 storage partitions. If the DS4700 storage subsystem is ordered with less than 64 partitions, various storage partition feature upgrade options can be purchased to increase the maximum number of supported storage partitions. - IBM DS4800 storage subsystem (machine type 1815): Depending on the ordering channels, the DS4800 storage subsystem is either shipped with 8 storage partitions or with a user selected 8, 16 or 64 storage partitions. If the subsystem is ordered with less than 64 partitions, an upgrade from 8 to 16, 8 to 64 or 16 to 64 partition storage partitioning premium feature option can be purchased. 4. Do not delete the Access LUN or Access Volume if you want to manage the DS4000 storage subsystem 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. 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. 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 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. 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 subsystems DS4500, DS4400 and FAStT500 (IBM machine type 1742 and 3552) have two ports per controller - one per minihub slot. The DS4000 storage subsystems DS4300 (IBM machine type 1722) and DS4100 (IBM machine type 1724) have two ports per controller. The DS4000 storage Server FAStT200 (IBM machine type 3542) has only one port per controller. The DS4700 storage subsystem (IBM machine type 1814) has up to four ports per controller. The DS4800 storage subsystem (IBM machine type 1815) has four ports per controller. 8. 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. 9. 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. 10. 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. 11. 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) ======================================================================= 3.0 Configuration Information ---------------------------------------- 3.1 Configuration Settings ------------------------------------ 1. When using the Linux RDAC as the multipath driver, the host type can be set to either LNXCLVMWARE(LNXCL) or Linux host type. If the chosen host type is Linux, one must run the DisableAVT_Linux.script to disable the Auto logical drive transfer feature. If the DisableAVT_Linux.script is not run, the mapped LUNs might not failover/failback properly when using Linux RDAC as the multipath driver. 2. By default, the IBM DS4000 Storage Manager Client 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 the NVSRAM with Storage Partitions, you may have to change the default host type to match the host system OS like Linux or LNXCL(LNXCLVMWARE). After upgrading the NVSRAM, the default host type is reset to Windows 2000/Server 2003 non-clustered for DS4000 storage subsystem with controller firmware version 06.15.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. 3. When you are configuring IBM machine type 1722, 1724, 1742, 3542, 1814, 1815 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.script: 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.script: 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.script: 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.script: 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.script: 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.script: 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) - EnableCntlReset.script: This script is to set the HostNVSRAMByte offset 0x1B of the LnxclVMWare host type NVSRAM region to 1 for enabling the propagation of the bus/target/LUN reset that one controller received to the other controller in a dual controller DS4K subsystem. - DisableCntlReset.script: This script is to set the HostNVSRAMByte offset 0x1B of the LnxclVMWare host type NVSRAM region to 0 for disabling the propagation of the bus/target/LUN reset that one controller received to the other controller in a dual controller DS4K subsystem. The default propagation of the bus/target/LUN reset setting for the LnxclVMWare host type is to enable it. This script should be used only when the following conditions are met. . The DS4000 storage subsystem did not have any LUNs mapped to any Linux hosts that are part of Linux cluster configuration. . The DS4000 storage subsystem did not have any LUNs mapped to any VMWare hosts. . The Linux hosts use Linux RDAC as multipath driver. . The host type of defined host ports is LnxclVMWare. Inappropriate use of this script might cause loss of access to the mapped LUNs from the Linux or VMware hosts. 5. When you are configuring IBM machine type 1722, 1724, 1742, 1814, 1815 or 3552 storage subsystems in clustered Remote Mirror configurations, contact IBM support for supported cluster configurations and instructions for configuring IBM storage controllers in clustered Remote Mirror configurations. 6. When using the Linux RDAC as the multipathing driver, the "LNXCL" host type must be used instead of the linux host type and there is not a requirement that the UTM(Access LUN) must be removed from the LNXCL Storage Partitioning partition. 7. If a host in a cluster server configuration lost a physical path to a DS4000 storage subsystem controller, the logical drives that are mapped to the cluster group will periodically failover and then failback between cluster nodes until the failed path is restored. This behavior is the result of the automatic logical drive failback feature of the RDAC multipath driver. The cluster node with a failed path to a DS4000 controller will issue a failover command of all logical drives that were mapped to the cluster group to the controller that it can access. After a programmed interval, the nodes that did not have failed path will issue failback command for the logical drives because they can access the logical drives both controllers, resulting in the cluster node with the failed path not be able to access certain logical drives. This cluster node will then issue a failover command for all logical drives, repeating the logical drives failover-failback cycle. The workaround is to disable this automatic failback feature. For Linux cluster (SteelEye) environments, perform the following steps: a. Open the /etc/mpp.conf file, and change the DisableLunRebalance parameter to 3. Save the changes. b. From a shell prompt, type the following command, and press Enter: mppUpdate c. Reboot the computer for the changes to take effect. d. Repeat this procedure on any system in the cluster configuration that has the Linux RDAC driver installed. ======================================================================= 3.2 Hardware status and information -------------------------------------------------- New installations for IBM Machine types 1722, 1742, 1814, 1815 and 1724 should be installed the following FC Host Bus Adapter (HBA) 1.
