This firmware version will support the IBM DS3000 System Storage DS3200, DS3300 and DS3400 storage subsystems. The IBM DS Storage Manager host software version 10.70.xx.xx or higher is required to manage DS3000 storage subsystems with controller firmware version 07.35.71.00 installed. The newer IBM DS Storage Manager host software version 10.77.xx.xx or higher is recommended to manage DS3000 storage subsystems with controller firmware version 07.35.73.00 installed. ATTENTION: DO NOT DOWNLOAD THIS CONTROLLER FIRMWARE ON ANY OTHER IBM SYSTEM STORAGE other than the DS3000 STORAGE SUBSYSTEMS. Refer to the IBM Support Web Site for the latest Firmware and NVSRAM files and DS Storage Manager host software for the IBM DS3000 Storage Subsystems. http://www.ibm.com/storage/support/disk/ ======================================================================= 1.1 Limitations --------------------- NOTE: For limitations in certain operating system environment, refer to the readme file that is included in the DS Storage Manager host software package for that operating system environment. Limitations with versions 07.35.73.00 release. none Limitations with versions 07.35.71.00 release. none Limitations with versions 07.35.66.00 release. none Limitations with versions 07.35.57.00 release. 1. DS3300 Linux hardware initiator iSCSI solution is currently only supported when using a version of SANSurfer for iSCSI starting with version 5.00.32. 2. IBM AIX currently only supports the DS3400 storage subsystem. 3. During deletion of a logical drive it is possible that a "ghost" (I.E. a logical drive displayed with a dotted line picture) will be visible. If this occurs you will need to go to Modify -> Edit Host-to-Logical Drive Mappings. Then select the logical drive in question and click on the remove option. This will destroy the "ghost" logical drive. 4. Arrays created using RAID levels 3,5, or 6 that will be mapped to an AIX host, need to contain at a minimum five (5) hard drives. 5. VMware is currently only supported on the DS3300 using software initiator. 6. There is no Solaris management client for DS3000 storage subsystems. 7. After updating the 1726 subsystem from 06.xx to 07.xx you will need to re-add the subsystem to the storage manager enterprise manager window. 8. Currently when running SLES 9 SP4 it is possible to see intermittant IO failures after a path failure. This issue is still being investigated but the following steps will insure that the failure does not occur: Edit the kernel boot line in your /boot/grub.conf file and add mem=3G boot option to the command line. 9. When using a DS3200 with an IBM BladeCenter chassis you will not be able to swap installed and configured blades into an additional chassis and maintain those connections. You must power cycle the DS3200 before connecting it to the new BladeCenter chassis. 10. After a path failure on a DS3200 while running Netware 6.5 patch 7 you will need to shut the host down and restart it. If you attempt to rebalance the LUNs using the embedded multi-path driver IO failures could occur when the LUNs attempt to fail back. 11. After restoring the path to a DS3300 controller with multiple hosts attached in a short cable pull test (3 seconds or less) it is possible that IO errors could occur. Insure that you always allow for enough time to failover all of the logical drives before restoring the path. 12. Currently the device drivers for RHEL 4.5 and above for the MPT SAS driver do not support the Enhanced Error Handling supported by the IBM JS blades. If you are running these Operating systems you could see errors during path restoration indicating that the MPT SAS driver has crashed. 13. When using a sofware iSCSI initiator to connect to a DS3300, performing a large number of controller reboots/resets may result in the software initiator running out of I/O buffer credits and thus halt I/O to the controller. In this event, the host may need to be restarted to clear the I/O buffer credit region and allow I/O. 14. If you are running SLES 10 with XEN support enabled you will be unable to connect to a DS3300 controller. 15. Only the software iSCSI initiator is supported on this firmware version. An RPQ will be required if a hardware iSCSI initiator is required for your application/environment. If an RPQ is required, please contact your IBM representative for assistance with submitting an RPQ. ======================================================================= 1.2 Enhancements ----------------- The DS3000 storage subsystem controller firmware version 07.35.73.00 used in conjunction with DS Storage Manager 10.77.xx.xx and later provides support for; - Provides bug fixes as listed in the changelist file.

DS3400 - Dual Controller : N1726D340R335V09.dlp Note: The DS3000 storage subsystems that are shipped from the factory may show the NVSRAM version with a different first character prefix other than the "N" prefixed as stated. As long as the rest of the version information after the first character are the same, both the manufacturing NVSRAM version and the "N" prefixed NVSRAM version are the same. You do not need to update your DS3000 storage subsystem with the "N" prefixed NVSRAM version as stated above. For example, for a DS34000, the N1726D340R917V15 and M1726D340R917V15 (or C1726D340R917V15 or D1726D340R917V15, etc...) versions are the same because both versions share the same "1726D340R917V15" string. The M1726D340R917V15 (or C1726D340R917V15 or D1726D340R917V15, etc...) version was loaded to the DS3400 storage subsystem at the factory. The N1726D340R917V15 version is the one that was posted to the DS3000 support web site for download. Refer to the following IBM System Storage™ Disk Storage Systems Technical Support web site for the latest released code levels. http://www.ibm.com/storage/support/disk/ ======================================================================= 2.0 Installation and Setup Instructions ----------------------------------------- ATTENTION: If you have not already done so, please check the Dependencies section for ANY MINIMUM FIRMWARE REQUIREMENTS for the DS3000 storage server controllers, the drive expansion enclosure ESMs and the hard drives in the DS3000 configurations before upgrading the controller firmware.

The IBM System Storage DS Storage Manager version 10 Installation and Support Guide for Microsoft Windows Server, Linux, Novell Netware, and VMWare ESX Server are available on IBM's Support Web Site as a down-loadable Portable Document Format (PDF) file. 2. The IBM System Storage DS Storage Manager version 10 Installation and Support Guide for AIX and Linux on POWER is available on IBM's Support Web Site as a down-loadable Portable Document Format (PDF) file. 3. The DS3000 Premium Feature - storage partitioning, plus Copy Services Premium Features - FlashCopy, VolumeCopy and FlashCopy VolumeCopy - are options purchased separately. 4. Enablement of the 07.35.71.00 controller firmware provides support for up to 4 storage partitions for the DS3200, DS3300 and DS3400. If additional storage partitions are needed, various storage partition feature upgrade options can be purchased to increase the maximum number of supported storage partitions. 5. The Storage Manager (SM) host software version 10.77.xx.xx client script window looks for the files with the file type of ".script" as the possible script command files. 6. If the management port is connected to a network infrastructure that will periodically be performing security port scans, please ensure that the switch port that connects to the management port(s) is set to auto-negotiate. In some instances, when a port is set to a dedicated link speed, after a port scan the management port will become unresponsive and will not recover until after the storage subsystem is power cycled. ======================================================================= 4.0 Configuration Information ----------------------------- 4.1 Configuration Settings -------------------------- 1. By default the Storage Manager software does not automatically map logical drives if the storage partitioning feature is enabled. This means that the logical drives are not automatically presented to host systems. Refer to the IBM DS Storage Manager documentation or online help to learn more about creating storage partitions and changing host types. 2. When configuring a DS3300 or DS3400 storage subsystem as boot device, please refer to chapter 5 in the latest Storage Manager Installation and Host Support Guide for detailed instructions on this procedure. ======================================================================= 4.2 Unsupported configurations ------------------------------ The configurations that are currently not being supported with controller firmware version 07.35.73.00 in conjunction with DS Storage Manager version 10.77 and higher are listed below: 1. A configuration in which either a software or hardware iSCSI initiator is directly connected to a DS3300 storage subsystem. 2. A configuration in which the host is connected to a iSNS server using only IPv4 and the DS3300 is connected to the iSNS server using only IPv6. ======================================================================= 5.0 Unattended Mode --------------------- N/A ======================================================================= 6.0 WEB Sites and Support Phone Number ---------------------------------------- 6.1 IBM System Storage Disk Storage Systems Technical Support web site: http://www.ibm.com/storage/support/disk/ 6.2 IBM System Storage Marketing Web Site: http://www.ibm.com/storage/disk 6.3 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 DS Storage Manager host software, the DS3000 storage subsystem controller firmware, the EXP3000 drive expansion enclosure ESM firmware and the drive firmware at the time of the initial installation and when product updates become available.
