Please refer to the README files that are packaged with the IBM DS4000 host software version 9.14 packages for various DS4000 support operating systems for host software related limitations. ======================================================================= 1.2 Enhancements ----------------- With this version 06.15.15.xx of controller firmware, the controllers in the DS4800 storage subsystems (machine type 1815 - all models) utilize all of the available data cache memory installed in each controller blade for I/O caching. Previously with controller firmware version 06.14.xx.xx, the DS4800 controllers used only the first 1G bytes of the installed data cache memory per controller for I/O caching. In addition, a new model of the DS4800 storage subsystem with 8G of cache per controller is also supported with this controller firmware version. Please refer to the New Features section of the IBM DS4000 Storage Manager version 9 Installation and Support Guide for the appropriate host server operating system environment for additional information about the IBM DS4000 Storage Manager version 9 enhancements. ======================================================================= 1.3 Prerequisites ------------------ The DS4000 controller firmware and NVSRAM file that are packaged with this README file can ONLY be loaded in the following DS4000 storage subsystems: - DS4800 storage subsystems DO NOT DOWNLOAD this controller firmware on any other DS4000 storage servers. There is not any checking for this restriction inside the DS4000 storage manager client program. In addition, the procedure to recover the DS4000 storage subsystem that was inadvertently loaded with this firmware file will require downtime to the DS4000 storage subsystem. Also see next section - Dependencies. ======================================================================= 1.4 Dependencies ----------------- ATTENTION: 1. 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. 2. The only DS4000 storage subsystems that are supported by the 06.14.xx.xx or 06.15.xx.xx controller firmware version are the DS4800. Currently, there are not any controller firmware packages version 06.14.xx.xx or 06.15.xx.xx for other DS4000 storage subsystems besides the DS4800. Do not download this controller firmware on any other DS4000 storage subsystems. 3. 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. 4. 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 host software version 09.15.xx.xx provides full management support for IBM machine types 3552 and 3542 storage controllers that have at least firmware version 04.01.xx.xx (05.xx.xx.xx in Microsoft Windows environment), IBM Machine type 1742- 900 and 1742 storage controllers that have at least firmware version 05.00.04.xx, IBM Machine type 1722 storage controllers that have at least firmware version 05.3x.xx.xx or IBM Machine type 1815 storage controllers that have at least firmware version 06.14.xx.xx. The only IBM DS4000 Storage Manager version 09.1x.xx.xx supported management function on controllers with non-supported controller firmware versions is controller firmware and NVSRAM download. ======================================================================= 2.0 Change History ----------------------------- ====================================================================== 2.1 Version History ----------------------------- This is the latest release of IBM DS4000 TotalStorage™ controller firmware/NVSRAM for the DS4800 storage subsystems. Version 06.15.15.xx dated 08/30/2005 - Support for the new DS4800 storage subsystems model 88A/H with 8G of controller cache per controller. Version 06.15.11.xx dated 6/28/2005 - Enable support for controller cache memory above 1G for the DS4800 storage subsystems (M/T 1815 - all models) Version 06.14.29.xx dated 5/16/2005 - Support for the DS4800 storage subsystems (M/T 1815-models 82A/H, 84A/H) ======================================================================= 2.4 Code levels at time of release are as follows ------------------------------------------------- 1. Storage Controller Firmware versions: a. DS4800: FW_DS4800_06151500 Note: The same firmware file can be used for upgrading the controller firmware through the SMClient GUI or through the controller serial port. Do not attempt to download the firmware through serial port without the present of IBM Support personnel. A botched controller firmware download via the serial port can cause to the controller to be inoperable. 2. Storage Controller NVSRAM versions: a. DS4800: N1815D480R914V05 Refer to the following IBM TotalStorage™ Disk Storage Systems Technical Support web site for the latest released code levels. http://www.ibm.com/servers/storage/support/disk/ ======================================================================= 3.0 Installation and Setup Instructions ----------------------------------------- ATTENTION: If you have not already done so, please check the Dependencies section for ANY MINIMUM FIRMWARE REQUIREMENTS for the DS4000 storage server controllers, the drive expansion enclosure ESMs and the hard drives in the DS4000 configurations before upgrading the controller firmware. Make any firmware updates as required BEFORE proceeding to upgrade the DS4000 controller with the firmware and NVSRAM files packaged with this README file. FAILURE to observer the minimum firmware requirement might cause your DS4000 storage subsystem to be OUT-OF-SERVICE. 3.1 Updated the firmware of the ESMs in the attached drive expansion enclosures to latest levels before the upgrading the controller firmware. To download drive expansion ESM firmware, do the following: a. Open the Subsystem Management window. b. Click Advanced => Download => Environmental(ESM) Card Firmware. Follow the online instructions. Note: If the existing controller firmware in the DS4000 storage server is of version 05.30.xx.xx or higher, the drive expansion enclosure ESM firmware can be updated online with no downtime if both ESMs in each of the drive expansion enclosures are functional and one (and ONLY one) drive expansion enclosure is selected in the ESM firmware download window for ESM firmware updating at a time. Note: The latest ESM firmware versions for EXP100 and EXP710 drive expansion enclosures are 9554 and 9631, respectively. 3.2 Important: You must install the firmware update prior to downloading the NVSRAM update. To download firmware, do the following: a. Open the Subsystem Management window. b. Click Storage Subsystem => Download => Firmware. Follow the online instructions. To download NVSRAM, do the following: a. Open the Subsystem Management window. b. Click Storage Subsystem => Download => NVSRAM. Follow the online instructions. 3.3 (if applicable) Enable the FC/SATA intermix premium feature using the premium key file. 3.4 After the controller firmware and NVSRAM is updated, consider checking the IBM TotalStorage™ Disk Storage Systems Technical Support web site for the latest released hard drive firmware. To download hard disk drive firmware, do the following: a. Schedule down time because the drive firmware upgrades require that there are no HOST IOs to be sent to the DS4000 controllers. b. Open the Subsystem Management window. c. Click Advanced => Download => Drive Firmware. Follow the online instructions. Note: with controller firmware version 06.1x.xx.xx or later, multiple drives from up to four different drive types can be updated at the same time. ======================================================================= 3.2 Helpful Hints ------------------ 1. IBM DS4800 storage subsystem (machine type 1815): Depending on the models, the 1815 storage subsystem is either shipped with 8 storage partitions (model 82H/84H/88H) or with a user selected 8, 16 or 64 storage partitions (model 82A/84A/88A). 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. 2. 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. 3. 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 subsystem FAStT200 (IBM machine type 3542) has only one port per controller. The DS4800 (IBM machine type 1815) has 4 ports per controller. 4. 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. 5. 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. 6. 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. 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) 8. Inter-operability with tape devices is supported on separate HBA and switch zones. ======================================================================= 4.0 Configuration Information ----------------------------- 4.1 Configuration Settings -------------------------- 1. By default the IBM DS4000 Storage Manager 9.15 firmware does not automatically map logical drives if storage partitioning feature is enabled. This means that the logical drives are not automatically presented to host systems. For a new installation, after creating new arrays and logical drives; a. If your host type is not Windows NT, create a partition with your host type and map the logical drives to this partition. b. If your host type is Windows NT, you can map your logical drives to the "Default Host Group" or create a partition with a NT host type. When upgrading from previous versions of IBM DS4000 Storage Manager to version 9.15. a. If upgrading with no partitions created and you have an operating system other than Windows NT, you will need to create a partition with your host type and map the logical drives from the "Default Host Group" to this partition. b. If upgrading with Storage Partitions and an operating system other than Windows NT is accessing the default host group, you will need to change the default host type. After upgrading the 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. 2. When you are configuring IBM machine type 1815 storage subsystems as boot devices, contact IBM support for supported configurations and instructions for configuring LUNs in the IBM storage subsystems as boot devices. 3. 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_W2K_S2003_noncluster.scr: The script will enable automatic logical drive transfer (AVT/ADT) for the Windows 2000/Server 2003 non- cluster heterogenous host region. The default setting is to disable AVT for this heterogenous host region. This setting is one of the requirements for setting up the remote boot or SAN-boot. 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 Windows 2000/Server 2003 non-cluster host type with the appropriate host type that needs to have AVT/ADT enabled) - DisableAVT_W2K_S2003_noncluster.scr: The script will disable the automatic logical drive transfer (AVT) for the Windows 2000/Server 2003 non-cluster heterogenous host region. This script will reset the Windows 2000/Server 2003 non-cluster AVT setting to the default. (This script can be used for other host type if modifications are made in the script, replacing the Windows 2000/Server 2003 non-cluster host type with the appropriate host type that needs to have AVT/ADT disabled) - EnableAVT_Linux.scr: The script will enable automatic logical drive transfer (AVT) for the Linux heterogenous host region. Do not use this script unless it is specifically mentioned in the applicable instructions. - DisableAVT_Linux.scr: The script will disable the automatic logical drive transfer (AVT) for the Linux heterogenous host region. Do not use this script unless it is specifically mentioned in the applicable instructions. - disable_ignoreAVT8192_HPUX.script: This script will disable the DS4000 storage subsystem ignoring of AVT requests for the HP-UX server specific read pattern of 2 blocks at LBA 8192. The AVT ignoring request for the LBA 8192 reads was implemented to prevent a possible occurrence of an AVT storm caused by the HP-UX server probing in the wrong order of available paths to the volume(s) when it detect server to LUN path failure. Use this script only when you do not have defined LVM mirrored volumes using the mapped logical drives from the DS4000 storage subsystems. Please contact IBM support for additional information, if required. - enable_ignoreAVT8192_HPUX.script: This script will enable the DS4000 storage subsystem ignoring of AVT requests for the HP-UX server specific read pattern of 2 blocks at LBA 8192. The AVT ignoring request for the LBA 8192 reads was implemented to prevent a possible occurrence of an AVT storm caused by the HP-UX server probing in the wrong order of available paths to the volume(s) when it detect server to LUN path failure. Use this script only when you do have defined LVM mirrored volumes using the mapped logical drives from the DS4000 storage subsystems. Please contact IBM support for additional information, if required. 4. When you are configuring IBM machine type 1815 storage controllers in host cluster Remote Mirror configurations, contact IBM support for supported host cluster configurations and instructions for configuring IBM storage controllers in clustered Remote Mirror configurations. ======================================================================= 4.2 Unsupported configurations ------------------------------ The following lists configurations that are currently not being supported with IBM DS4000 Storage Manager 9.15. 1.
