The following table shows the first four digits of the latest controller firmware versions that are currently available for various models of the DS4000 storage subsystems. --------------------------------------------------- | | Controller firmware version | |------------------|--------------------------------| | DS4000 | | | storage subsystem| | | Model | | |------------------|--------------------------------| | DS4800 (1815) | 06.14.xx.xx | |------------------|--------------------------------| | DS4500 (1742) | 06.12.xx.xx | |------------------|--------------------------------| | DS4400 (1742) | 06.12.xx.xx | |------------------|--------------------------------| | DS4300 Turbo | 06.12.xx.xx | | Option (1722) | | |------------------|--------------------------------| | DS4300 | 06.12.xx.xx | | Standard Option | | | (1722) | | |------------------|--------------------------------| | DS4300 Single | 05.34.xx.xx | | Controller Opt. | (for DS4300 SCU | | (1722) | only) | |------------------|--------------------------------| | DS4100 (1724) | 06.12.xx.xx | | | | |------------------|--------------------------------| | DS4100 Single | 05.42.xx.xx | | Controller Opt. | (for DS4100 SCU | | (1724) | only) | |------------------|--------------------------------| | FAStT500 (3552) | 05.30.xx.xx | |------------------|--------------------------------| | FAStT200 (3542) | 05.30.xx.xx | --------------------------------------------------- Note: New features that are introduced with the controller firmware version 06.14.xx.xx or later will not be available for any DS4000 storage subsystem controllers without the controller firmware version 06.14.xx.xx installed. Similarly, new features that are introduced with the controller firmware version 06.12.xx.xx or later will not be available for any DS4000 storage subsystem controllers without the controller firmware version 06.12.xx.xx installed. ======================================================================= 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 version 9.14.xx.05 and DS4000 controller firmware version 06.14.xx.xx release None New limitations with Storage Manager 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. The SMclient, SMUtil and SMAgent programs are installed into the /opt/IBM_FAStT directory instead of the /opt/IBM_DS4000 directory. New 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 workaround 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) 3. There are not DS4000 Storage Manager version 9.12 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. 4. 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 indefinitely. 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) New limitations with 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. 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 currrently 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/NVSRAM to the DS4000 storage subsystem controllers with IOs to the host servers) is not supported when upgrading the controller firmware from a 05.xx.xx.xx version to a 06.1x.xx.xx version. ALL IOs must be stopped during the version 06.1x.xx.xx controller 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. 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." 8. 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 proceed. For example, route add -host 255.255.255.255 eth0 9. 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. Limitations with Storage Manager version 8.4x.xx.xx (and earlier) and DS4000 controller firmware version 05.4x.xx.xx (and earlier) releases 1. In the DS4000 Storage Manager 9.12 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. 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. 4. This following behavior applies for the direct Fibre Channel connection setup between the DS4300 storage subsystem 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 subsystem. 5. When managing the DS4000 storage subsystems 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. 6. 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 FibreChannel 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 server 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. 7. When migrating array(s) from a dual controller DS4000 storage subsystem to a single controller DS4000 storage subsystem, 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 subsystem. Otherwise, the array(s) will not be added to the single controller DS4000 storage subsystem correctly which might cause problems. 8. When managing a single controller DS4000 storage subsystem 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. 9. 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. 10. 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. 11. 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. 12. 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:. 13. 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. 14. 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. 15. 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. 16. 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. 17. Inter-operability with tape devices is supported on separate HBA and switch zones. ======================================================================= 1.3 Enhancements --------------------------- The DS4000 Storage Manager version 9.14 host software for Linux operating systems provides support for the new member of the DS4000 storage subsystem family - the DS4800 (M/T 1815 models 82A/H, 84A/H). It also provides Enhanced Remote Mirroring support for the DS4100 storage subsystems with standard/base option and the FC/SATA intermix support for the DS4100 storage subsystems with standard/base option. Note: The minimum version of controller firmware for the DS4800 is 06.14.xx.xx. Starting with this release of the DS4000 Storage Manager host software for Linux, a single DS4000 Storage Manager host software installer wizard is provided to automate the installation of multiple individual host sofware packages (SMruntime, SMclient, SMutil and SMagent) in Linux operating system environment. Note: this wizard does not install the Linux RDAC driver package. Linux RDAC package must be installed by itself. 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 Pre-Requisites -------------------------- IBM xSeries and other Intel-based 32 bit servers with minimum 512MB Memory with 512 KB L2 Cache Pentium II 450Mhz processor minimum or any AMD64 or EM64T processor architecture servers with a minimum of 512MB Memory. The servers must have the 32bit version of Linux OS installed. (also see Dependencies section) ======================================================================= 1.5 Dependencies -------------------------- ATTENTION: 1. 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. 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. 3. CURRENTLY, THE ONLY DS4000 STORAGE SUBSYSTEMS THAT ARE SUPPORTED BY THE 06.12.XX.XX CONTROLLER FIRMWARE VERSION ARE THE DS4100 WITH STANDARD (BASE) OPTION, THE DS4300 WITH STANDARD (BASE) 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 controller firmware version are the DS4800. Currently, there are not any controller firmware packages version 06.14.xx.xx for other DS4000 storage subsystems besides the DS4800. 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.

Then, go to this directory, locate the Linux or Linux_IA64 directory to access the Storage Manager version 9.14 host software installation file(s). 3.1 Step-by-step instructions for this code update are as follows ----------------------------------------------------------------------------------------- NOTE: (for installation in Redhat EL AS 3.0 environment only) Some packages of JRE 1.3.1 may not contain all of the files necessary for the IBM DS4000 Storage Manager host software to run correctly on RedHat Enterprise Linux, version 3.0. If you are missing these files, the client and agent software will not run on that system, and an error message similar to the following example may display: /opt/SM8/jre/bin/i386/native_threads/java: error while loading shared libraries: libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file or directory To determine if the required compatibility library is installed, type the following at a terminal window command prompt: "rpm -q compat-libstdc++" The system will respond that the library package is not installed, or display the current version of the package. Verify that the current compatibility library matches the following package version: "compat-libstdc++-7.3.2.96.122" If the library is installed, proceed with the code installation procedure listed below. If not, you can download the library from RedHat Support web site. 1. Install and update the driver for the IBM DS4000 Host Adapter. a. Install the hardware by using the instructions that come with the adapter. b. Install the IBM DS4000 Host Adapter driver by using the instructions provided in the readme file located in the HostAdapter directory on the installation CD or downloaded with the device driver source package from the IBM support web site. c. If one chooses Linux RDAC as multipath failover/failback driver, install the IBM DS4000 Linux RDAC driver by using the instructions provided in the readme file located in the LinuxRDAC directory on the installation CD or downloaded with the device driver source package from the IBM support website. 2. Install the new Storage Manager host software version from the CD-ROM directory or from the host software package that you downloaded from the IBM Support Web site. If there is previous version (7.x, 8.x or 9.1x) of the IBM DS4000 Storage Manager host software installed in the server, you have to uninstall it first before installing the new version of the storage manager host software. Refer to the IBM DS4000 Storage Manager version 9 Installation and Support Guide for Windows 2000/Server 2003, Netware, ESX Server, and Linux for detailed installation instructions. 3. If the managed DS4000 storage subsystem had the FC/SATA intermix premium feature enable, do not continue with the next step 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 from version 06.10.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. 4. Upgrade the DS4000 storage subsystem firmware in the following order - the drive expansion enclosure ESM code, controller firmware and NVSRAM, and then hard drive firmware code. Refer to the IBM DS4000 Storage Manager version 9 Installation and Support Guide for Windows 2000/Server 2003, Netware, ESX Server, and Linux or the online help in the Subsystem Management window for detailed instructions. CAUTION: 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 server controller and the hard drive firmware. 5. (if applicable) Re-enable the FC/SATA intermix premium feature using the premium key file. Refer to the http://www.ibm.com/servers/storage/support/disk IBM TotalStorage™ Disk Storage Systems Technical Support web site for the the latest DS4000 Storage Manager host software, the DS4000 controllers firmware, the drive expansion enclosure ESM firmware and the hard disk drive code. ======================================================================= 3.2 Refer to the HostAdapter or LinuxRDAC directory in 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 DS4000 FAStT, FC-2 and FC2-133 Host Bus Adapter device driver version 7.05.00-fo (failover version) and 7.05.00 (non-failover version) for Linux 2.4 kernel (RHEL 3 and SLES 8) 2. IBM DS4000 FAStT, FC-2 and FC2-133 Host Bus Adapter device driver version 8.00.02 (failover and non-failover) for Linux 2.6 kernel (SLES 9) 3. IBM FAStT_MSJ 2.0.30 build 18 4. IBM DS4000 storage subsystem Linux RDAC version 09.00.A5.09 ======================================================================= 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. - IBM DS4800 storage subsystem (machine type 1815): Depending on the ordering channels, the 1815 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. 3. 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. 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 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. 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 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 DS4800 storage subsystem (IBM machine type 1815) has four ports per controller. 7. All drive enclosures on any given loop should have complete unique ID's assigned to them. For example, in a maximum configured DS4500 storage server, 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. Enclosures id's 00 ~ 09 should not be used and enclosure id's with the same single digit such as 11 and 21 should not be used on the same drive loop. 8. 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. 9. 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. 10. 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 9.12 or later vs. enableAVT.scr for pre-9.12) ======================================================================= 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 9.1x 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 the NVSRAM with Storage Partitions, you may have to change the default host type to match the host system OS like Linux or LNXCL. 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 06.14.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. 3. When you are configuring IBM machine type 1722, 1724, 1742, 3542, 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.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 1722, 1724, 1742, 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. ======================================================================= 4.2 Hardware status and information -------------------------------------------------- New installations for IBM Machine types 1722, 1742, 1815 and 1724 should be installed with the IBM DS4000 and FC-2/FC2-133 Host Adapter. The device driver version should be 7.05.00 or 08.00.02 for FAStT and FC-2/FC2-133 Host Adapters depending on the whether the Linux kernel version is of 2.4 or 2.6, respectively.. 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 DS4000 Storage Manager Version 9.12. 1.
