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 | --------------------------------------------------- New features that are introduced with the controller firmware version 06.14.xx.xx or later will not be available for any DS4000 storage server controllers without the controller firmware version 06.14.xx.xx installed. 1.2 Limitations (not AIX limitations, but DS4000 Storage Manager 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. Limitations with Storage Manager version 9.10.xx.05 and DS4000 controller firmware version 06.10.11.xx release 1. Do not update the DS4000 storage subsystem controller firmware to version 06.1x.xx.xx from versions 05.4x.xx.xx or earlier if the EXP700 ESM firmware of the attached EXP700 was not at 9326 or higher. If the EXP700 ESM firmware is earlier than the 9326 versions, the EXP700 enclosure and the installed drives may not be displayed in the DS4000 subsystem management window after the controller firmware is upgraded to 06.1x.xx.xx version. The work around is to update the EXP700 ESM firmware to the version 9326 or higher first before upgrading the controller firmware to version 06.1x.xx.xx. (260160 - 82841) 2. When connecting the EXP100 drive expansion enclosures, one must set the single digit (X1) of the enclosure ID to unique values. This is to prevent the possibility that one of the drives in the EXP100 enclosures be assigned the same ALPA as the DS4000 controller blade under certain DS4000 storage subsystem reboot scenarios. (261188) Limitations with version Storage Manager version 9.10.xx.02 and DS4000 controller firmware version 06.10.06.xx release 1. The DS4000 Copy Service RVM is not supported at this time for the DS4100 and the DS4300 storage subsystem with Standard or Single Controller options. 2. In the Storage Manager version 9 client Subsystem Management window, the preferred owner of a defined logical drive can not be changed if the logical drive is not managed by the preferred owner/controller. The Storage Manager client will grey-out (not allowing one to select) the controller that is currently managing the logical drive in the selection list of the new preferred owner/controller. One is allowed to only select the controller that is not managing the logical to be the new preferred owner. There is no work-around. 3. Concurrent firmware download (downloading firmware with IOs) are not supported when upgrading the controller firmware from 05.xx.xx.xx version to 06.1x.xx.xx version. ALL IOs must be stopped during the 06.1x.xx.xx firmware upgrade from a 05.xx.xx.xx version. 4. Do not pull or insert drives during the drive firmware download. In addition, ALL IOs must also be stopped during the drive firmware download. Otherwise, drives may be shown as missing, unavailable or failed. 5. Controller diagnostics will not run in a DS4000 storage subsystem with single controller. 6. When instructed to remove and reinsert or to replace a hard drive, wait at least 70 seconds before inserting either the removed existing drive or the new drive into the drive slot. Then, wait up to 3 minutes for the drive to be spun up, recognized by the DS4000 storage subsystem and displayed in the Subsystem Management window before repeating the process for another hard drive. There is no work-around. Similarly, wait at least 70 seconds before reinserting either the removed existing ESM module or the new ESM module into the empty ESM slot in the EXP drive expansion enclosure. Then, wait up to 3 minutes for the ESM CRU to be recognized by the DS4000 storage subsystem and displayed in the Subsystem Management window before repeating the process for another ESM. There is no work-around. 7. SMdevices program does not return any information if the Access logical drive is not mapped to the AIX host connected to the DS4000 storage server. Map the Access logical drive to the AIX host and retry the command. 8. Dynamic Volume Expansion for AIX 5.3 must have PTF U499974 installed before expanding any file systems. Limitations with Storage Manager version 8.4x.xx.xx (and earlier) and DS4000 controller firmware version 05.4x.xx.xx (and earlier) releases 1. If the ESM firmware is 953A or earlier, no IOs are allowed during the duration that the EXP100 ESMs are being updated with new firmware, including clustering reservation checking IOs. 2. The DS4000 storage subsystem when configured with the DS4000 EXP100 SATA Drive Expansion Unit is currently reporting a higher frequency of informational events such as Destination Driver Events (DDEs) and Fibre Channel link up/down events ... in the DS4000 Controller event log compared to the DS4000 storage subsystem configured with Fibre Channel drives. Slower response times of SATA disk drives compared to Fibre Channel disk drives cause higher I/O retries from the DS4000 storage subsystem controllers, resulting in a greater number of informational events logged. In addition, the number of information events reported in the DS4000 storage subsystem event log will also grow in proportion to the increase in I/Os to the Logical Drives. In all cases, the DS4000 storage subsystem controller will always successfully service the timeout I/O on the subsequent retries. 3. After you replace a controller with a new controller in the single controller models of DS4000 storage subsystems, the premium features become unauthorized and are out of compliance. Any premium features not supported by the firmware of the new controller are unavailable. The work-around is to upgrade the firmware in the new controller to the same level as the removed controller and re-enable the premium features using the key files that you were provided when the premium feature was originally enabled. 4. When migrating drive Customer Replaceable Units (CRUs) from multiple DS4000 storage subsystems into a single destination DS4000 storage servers, all of the drive CRUs from the same DS4000 storage subsystem should be moved as a ‘set’ into the new destination DS4000 storage server. Before moving the next ‘set’ of drive CRUs, ensure that all of the drive CRUs for a single ‘set’ have been moved to the destination DS4000 storage subsystem. If drive CRUs are not moved as a ‘set’ to the destination DS4000 storage subsystems, the newly relocated array may not appear in the Subsystem Management window. 5. Enclosure IDs may be listed incorrectly in the Subsystem Management window, even if the Enclosure ID switch settings appear to be correct. This is because of the physical design and movement of the Enclosure ID switch, it is possible to leave the switch in a “dead zone” between ID numbers, which will return an incorrect Enclosure ID (this value is 0 in most cases) to the storage management software. When setting the Enclosure ID, ensure that the switch has actuated completely and has settled where the value is clearly visible in the viewing window. 6. To download controller firmware, you must select the drive where the firmware is located. If the drive you select does not respond, the File Selection dialog box will revert to the A: drive and display an error message that drive A: is not ready if there are no media in drive A:. 7. When saving the DS4000 storage subsystem event log entries, it may take up to several minutes to save all entries in the event log depending on the DS4000 management workstation resources. However, the DS4000 Storage Manager client GUI will show the completion of the event log saving almost instantly. The work around is to check the file size of the file that the event log entries are saved periodically; if the file size does not change, the event log saving is completed. 8. Do not perform other storage management tasks, such as creating or deleting logical drives, reconstructing arrays, and so on, while downloading the DS4000 storage subsystem controller firmware and DS4000 EXP ESM firmware. It is recommended that you close all storage management sessions (other than the session that you use to upgrade the firmware) to the DS4000 storage subsystem that you plan to update. 1.3 Enhancements ---------------- * This is the latest release of IBM Storage Manager version 9.14 The DS4000 Storage Manager version 9.14 host software for AIX 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.

These individual host software installation packages can also be downloaded at the IBM TotalStorage™ Disk Storage Systems Technical Support web site: http://www.ibm.com/servers/storage/support/disk/ 1.6 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 RESELLERS 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. IBM DS4000 Storage Manager version 9.1x host software requires the DS4000 storage subsystem controller firmware be at version 05.30.XX.XX or higher. The only IBM DS4000 Storage Manager version 09.1x.xx.xx for AIX management functions supported on DS4000 storage subsystems with controller firmware version 04.xx.xx.xx up to 05.2x.xx.xx is controller firmware and NVSRAM download. ============================================================================== 2.0 Change History ------------------ This is the latest release of IBM DS4000 Storage Manager host software for AIX.

Then, go to this directory, locate the AIX directory to access the Storage Manager version 9.14 host software installation file(s). Starting with the DS4000 storage manager version 9.12, all of the host software packages are included in a single DS4000 Storage Manager host software installer wizard. During the execution of the wizard, the user will have a choice to install all or only certain software packages depending the need for a given server. The version of the host-software installer wizard for this release is SMIA-AIX- 09.14.65.05.bin. IMPORTANT: The DS4000 Storage Manager host software installer wizard requires the installation of a graphics adapter in the AIX server for it to run. In addition, there must be at least 300MB of free space in the /opt directory for the installer wizard to install the host software packages. This installer wizard will install the following version of the host- software packages SMruntime: 09.14.65.00 SMclient: 09.14.G5.05 SMagent: 09.14.65.00 SMutil: 09.14.65.00 For AIX servers without the graphics adapter, individual host software installation packages are provided in the DS4000 Storage Manager Version 9.14 Support for AIX OSes CD under the directory named "/AIX/Individual packages". These individual host software installation packages can also be downloaded at the IBM TotalStorage™ Disk Storage Systems Technical Support web site. Refer to the http://www.ibm.com/servers/storage/support/disk IBM TotalStorage™ Disk Storage Systems Technical Support web site for information on the latest supported switches and the released code levels. ======================================================================= 3.0 Usage Notes and restrictions - AIX Platforms --------------------------------------------------- * It is important to set the queue depth to a correct size for AIX hosts. Having too large of a queue depth can result in lost file systems and host panics. Please refer to the IBM DS4000 Storage Manager Version 9 for UNIX and AIX Environments Installation and Support Guide for details. * Disabling Cache mirroring while the write-cache is permitted, but not recommended for most environments and applications. Loss of data could occur in the event of a controller failure (data in cache, but not written to disk). Refer to the Installation and Support Guide for further information. * SCSI-3 Persistent Reservation is supported on AIX with DS4000 Storage Systems. * Each AIX host (server) can support 1 or 2 DS4000 Partitions (or Host Groups), each with a maximum of 256 Logical Drives on AIX 5.1, 5.2 and 5.3. * For most applications, AIX host attaches to DS4000 storage subsystems using pairs of Fibre Channel adapters (HBA). For each adapter pair, one HBA must be configured to connect to controller "A" and the other to controller "B". Each HBA pair must be configured to connect to a single partition in a DS4000 storage subsystem or multiple DS4000 storage subsystems (fanout). To attach an AIX host to a single or multiple DS4000 with two partitions, 2 HBA pairs must be used. * SAN Switch Zoning Rules: Each HBA within a host must be configured in a separate zone from other HBAs within that same host, when connected to the same DS4000 controller port. In other words, only 1 HBA within a host can be configured in the same zone with given DS4000 controller port. * For most Direct-attach applications, the connections of DS4000 storage arrays on AIX should be configured with two HBAs for complete path availability. As such, dual-path configurations are restricted to the following: DS4100/DS4300 - one or two server configurations only (2 or 4 HBAs) Each HBA pair must be connected to both A & B host-side controller ports. DS4400/DS4500 - one or two server configurations only (2 or 4 HBAs) Each HBA pair must be connected to both A & B controllers. Only 1 connection on each host-side mini-hub can be used. * Single HBA configurations are allowed, but each single HBA configuration requires that both controllers in the DS4000 be connected to the host. In a switch environment, both controllers must be connected to the switch within the same SAN zone as the HBA. In a direct-attach configurations, both controllers must be "daisy- chained" together. This can only be done on the DS4400/DS4500 storage servers. * Multiple host attachment to a host-side mini-hub is not supported. * Storage Partitions and the Default Host Group DS4000 offers a premium feature called "Storage Partitioning" which enables users to associate a set of logical drives on a DS4000 Storage Server that can only be accessed by specified hosts and host ports. This association of logical drives to a set of hosts and host ports is called a Storage Partition. The benefit of defining Storage Partitions is to allow controlled access to the logical drives on the DS4000 storage subsystem to only those hosts also defined in the Storage Partition. Without the use of Storage Partitioning, all logical drives appear within what is called the Default Host Group, and they can be accessed by any fibre channel initiator that has access to the DS4000 host port. When homogeneous host servers are directly attached to the DS4000 storage subsystem, access to all logical drives may be satisfactory, or when attached to a SAN, zoning within the fabric can be used to limit access to the DS4000 host ports to specific set of hosts. The DS4300 base product (without the Turbo feature) provides the Default Host Group. Premium features are available to support four, eight, or sixteen Storage Partitions. If logical drive access control is required for your configuration, particularly in a SAN or multiple server environments, then it is recommended that you add the option for Storage Partitions. On other DS4000 storage subsystems which include a minimum number of Storage Partitions, Storage Partitioning should be used when configuring logical drives and hosts. * Booting from a DS4000 subsystem utilizing SATA drives for the boot image is supported but not recommended due to performance reasons. * Boot images can be located on a volume in DS4000 partitions that have greater than 32 LUNs per partition if utilizing AIX release CD's 5.2 ml-4 (5.2H) and 5.3.0 ml-0 or above. These CD's contain DS4000 drivers that support greater than 32 LUNS per partition. If older CD's are being used the boot image must reside in a partition with 32 LUNS or less. AIX 5.1 needs to retain the boot image on a volume that resided in a partition with less than 32 LUNs. * Dynamic Volume Expansion (DVE) is only supported on AIX 5.2 and 5.3. AIX 5.3 must have PTF U499974 installed before using DVE. * When booting from a DS4000 device, both paths to the boot device must be up and operational. Single HBA configurations are supported, but must have both controllers connected, as described above. * Path fail-over is not supported during the AIX boot process. Once the AIX host has booted, fail-over operates normally. * Interoperability with tape devices is supported on separate HBA and switch zones. * Interoperability with IBM 2105 and SDD Software is supported on separate HBA and switch zones. * Online concurrent firmware and NVSRAM upgrades of FC arrays are only supported when upgrading from 06.10.06.XX to another version of 06.10.XX.XX. APAR_aix_51 = IY64463 APAR_aix_52 = IY64585 APAR_aix_53 = IY64475 It is highly recommended that Online FW upgrades be scheduled during low I/O loads. Upgrading firmware from 05.xx.xx.xx to version 06.xx.xx.xx must be performed with no IOs. There is no work-around. * When using FlashCopy, the Repository Volume failure policy must be set to "Fail FlashCopy logical drive", which is the default setting. The "Fail writes to base logical drive" policy is not supported on AIX, as data could be lost to the base logical drive. * VolumeCopy must be used in conjunction with Flashcopy. The VolumeCopy source volume must be a FlashCopy copy. Refer to the IBM DS4000 Storage Manager version 9.1x Installation and Support Guides for AIX, HP-UX and Solaris for more information. * AIX Clustering (HACMP, PSSP, GPFS) is now supported with Storage Manager version 9.1x on FC systems. Please see one of the following Configuration Information documents for specific support information. These are located in the "Important notices and readmes" section on the DS4000 support web site. HACMP configuration information for DS4000 on pSeries/AIX Servers PSSP/GPFS configuration information for DS4000 on pSeries/AIX Servers * Do not perform other storage management tasks, such as creating or deleting logical drives, reconstructing arrays, and so on, while downloading the DS4000 storage subsystem controller firmware and DS4000 EXP100 ESM firmware. It is recommended that you close all storage management sessions (other than the session that you use to upgrade the firmware) to the DS4000 storage subsystem that you plan to update. * All drive enclosures on any given loop should have complete unique ID's assigned to them. Example for 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. * If there is previous version (8.x or 9.10) of the IBM DS4000 Storage Manager host software installed in the system, you have to uninstall it first before installing the new version of the storage manager software. Refer to the IBM TotalStorage™ DS4000 Storage Manager version 9 Installation and Support Guide for AIX, HP-UX, Solaris and Linux on POWER for instructions. 3.1 Helpful Hints ------------------------------- 1. The 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. 2. 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 3. 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. 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." 5. The DS4000 controller host ports or the Fibre Channel HBA ports can not be connected to a Cisco FC switch ports with "trunking" enable. You might encounter failover and failback problems if you do not change the Cisco FC switch port to "non-trunking" using the following procedure: a. Launch the Cicso FC switch Device Manager GUI. b. Select one or more ports by a single click. c. Right click the port(s) and select Configure, a new window pops up d. Select the "Trunk Config" tab from this window, a new window opens e. In this window under Admin, select the "non-trunk" radio button, it is set to auto by default. f. Refresh the entire fabric. 6. Serial connections to the DS4000 storage controller must be set to a baud rate of either 38200 or 57600. Do not make any connections to the DS4000 storage subsystem serial ports unless it is instructed by IBM Support. Incorrect use of the serial port might result in lost of configuration, and possibly, data. 7. Starting with the DS4000 Storage Manager (SM) host software version 9.12 or later, the Storage Manager client script window looks for the files with the file type of ".script" as the possible script command files. In the previous versions of the DS4000 Storage Manager host software, the script window looks for the file type ".scr" instead. (i.e. enableAVT.script for 9.12 or later vs. enableAVT.scr for pre-9.12) 3.2 Configuration settings ------------------------------ 1. By default the IBM DS4000 Storage Manager 9.1x firmware does not automatically map logical drives. This means that the logical drives are not automatically presented to host systems. a. For a new installation, after creating new arrays and logical drives, create a storage partition with the host type of AIX and map the logical drives to this partition or change the default host type to AIX if the Storage Partitioning premium feature is not enable. b. If you are upgrading the NVSRAM with Storage Partitions, you may have to change the default host type to match the host system OS. After upgrading the NVSRAM, the default host type is reset to Windows 2000/Server 2003 non-clustered for DS4000 storage server with controller firmware version 06.14.xx.xx or later. For DS4000 storage server with controller firmware version 06.12.xx.xx or earlier, it is reset to Windows non-clustered (SP5 or higher), instead. Refer to the IBM DS4000 Storage Manager online help to learn more about creating storage partitions and changing host types. ======================================================================= 4.0 WEB Sites and Support Phone Number -------------------------------------- 4.1 IBM TotalStorage™ Disk Storage Systems Technical Support web site: http://www.ibm.com/servers/storage/support/disk/ 4.2 IBM TotalStorage™ Marketing Web Site: http://www.ibm.com/servers/storage/disk 4.3 If you have any questions about this update, or problem applying the update go to the following HelpCenter World Telephone Numbers URL: http://www.ibm.com/planetwide IMPORTANT: You should download the latest version of the DS4000 Storage Manager host software, the DS4000 storage subsystem controller firmware, the DS4000 drive expansion enclosure ESM firmware and the drive firmware at the time of the initial installation and when product updates become available.
