This section highlights important features of DS System Storage. Figure 9 shows the two available options. Figure 9. Through this software, it is possible to perform administrative tasks such as creating arrays, logical drives, assigning logical drives to the host servers, setting up FlashCopy and Volume Copy, capturing logs for troubleshooting, and so on. Figure Enterprise Management GUI Turbo Key The Turbo Key is an optional premium feature that, when enabled, boosts the performance of a storage system across both throughput and IOP workloads, allowing you to take full advantage of DS performance capabilities with bandwidth-intensive applications.

Please see Important note 3 below Attention: With controller firmware 7. Please do not upgrade any storage subsystem to controller firmware to 7. A problem causing recursive reboots exists while using 7. This problem is fixed in 7. All subsystems currently using 7. Instructions for obtaining and using DbFix are contained in the 7.
Carefully read the firmware readme and the DbFix instructions before upgrading to firmware 7. For subsystems with firmware level 7.
Subsystems not currently using 7. DbFix may be run after upgrading to 7. DbFix is only applicable to subsystems using 7. All rights reserved. Note: Before using this information and the product it supports, read the general information in section 6. Note: Starting with the Storage Manager host software version Review section 3. In addition, it is also recommended for managing IBM DS storage subsystems with controller firmware version Please refer to this document for more information on new features and modifications.
Notes: 1. Please select the appropriate directory for your operating system environment. For the DS3x00 storage subsystems, please refer to the readme files that are posted in the IBM DS System Storage support web site for the latest information about their usage, limitations or configurations. No new limitations with Storage Manager version JAWs is only able to read out the title of the Window on which the initial focus is, it is not reading out any content inside that Window.
LSIP 2. When using OLH with JAWS screen reader, will have difficulty on navigating through the content in the Index Tab under Help content window due to incorrect and duplicate reading of the text. LSIP 3. When using the accessibility software JAWS 11 or 13, may hear the screen reading of a background window, even if the dialog is not in focus. LSIP 4. Will not be able to find Tray tab on storage array profile dialog launch. User needs to navigate to Hardware tab to find Tray tab.
LSIP 5. Will not be able to perform multiple array upgrades having different firmware versions. Please choose to upgrade arrays having different firmware versions separately. LSIP 6. This will prevent the host from encountering an IO error due to the host losing all paths should the alternate path fails. LSIP 7. Volume copy pair itself would get removed, if user attempts to create a shadow copy of a source volume of a volume copy pair using VSS provider. User needs to manually re-establish the volume copy relation.
This would result in re-copy of data from source volume to destination volume. LSIP 8. There may be some confusion when the data is compared between summary tab and storage array profile. There is no actual functionality issue. The way the contents are labelled is not consistent.
On a more than 30 drive disk pool with TPI enabled, the reconstruction progress indicator never moves because a finish notification is not sent to Storage Manager. When seeing this issue, just putting the replacement drive in the storage subsystem will allow the reconstruction to resume. New limitations with Storage Manager version Initiating dynamic logical drive expansion DVE on logical drives that are part of an asynchronous enhanced remote mirroring ERM without write order consistency will result in an error that is misleading because the controller is sending incorrect return code.
Cache settings can not be updated on thin logical drives. They can only be updated on the repository drives that are associated with these thin logical drives.
Wait at least two minutes after canceling a logical drive creation in the disk pool before deleting any logical drives just created in the disk pool from the cancelled logical drive creation process. T10PI errors were incorrectly reported in the MEL log for T10PI- enabled logical drives that are participated in an enhanced remote mirroring relationship during the logical drive initializations. The work-around is to use right-click on the mouse or the Windows key on the keyboard.
Storage Manager subsystem management window performance might be slow due to Java runtime memory leak. The work around is to close the Storage Manager client program after the management tasks are completed. Simultaneously updating ATA translator firmware on multiple 3 TB drives having an "Incompatible" status might result in an "interrupted" firmware download state that requires the power- cycling of the subsystem to clear it.
This limitation is reduced with the Storage Manager version However, in certain conditions, where there are not any available hot-spare drives for T10PI enabled arrays, it will be used by the controller as a hot-spare for a failed drive in these T10PI enabled arrays.
The controller will operate properly in this scenario and there are no adverse affects to the system while the 3 TB NL SAS drive is being used as the hot spare in a T10PI enabled array. This limitation is removed with controller firmware version 7.
Please upgrade the controller firmware version 7. Any search terms that were highlighted in the Search tab are still highlighted in the TOC tab. This always happens when you switch between the Search tab and the TOC tab.
Workaround: Select another topic in the TOC to remove all search term highlighting from all the topics. Support tab in the AMW kept open for longer duration will result in display of unevenly spaced horizontal marks. If the storage Manager is kept open for long durations a few grey lines may be seen on the Support Tab after restoring the AMW.
Re-launching the AMW eliminates this problem. The storage subsystem configuration script contains the logical drive creation commands with incorrect T10PI parameter. The workaround is to manually edit the file to change instances of dataAssurance parameters to T10PI. Please contact IBM resellers or Representatives for such support in the future.
Probability of this issue happening in the field is low. Novell was informed about this issue. In almost all cases, this command will be re-driven successfully by the controller. Impact should be negligible. If the user does not map volumes to a host that can be seen through different host interfaces this problem will not occur. Workaround: Place controller online and reboot the server to see all volumes again. The devices will be disconnected from the host until the iSCSI sessions are re-established.
Configure the iSCSI service to start automatically on boot. CFW Upgrade on 4. The crashes appear to happen randomly with other applications as well.?
After the crash the menu reloads automatically.? Dismiss the prompt and the host will reload the application.? This problem appears to be a vendor issue. VMware has suggested VMware 4.
No support was issued for RHEL 4. Update SLES Note that this kernel version has not been fully certified by LSI and should only be used if this issue is encountered. Bugzilla contains issue details and fix provided by Novell. LifeKeeper 7. In this case each port will be represented as a host, and LifeKeeper will identify both separately. Another way to avoid the issue is to use MPP as the failover driver. Workaround: None. This can be avoided by not using raw device mappings and instead using virtual disks.
If raw device mappings are required, they must be used with virtual compatibility mode selected when adding the disks to the guest OS.
Permanent restriction. The only recovery method is to rebooting the failed VM host. Readme CD directory for information on the legacy limitations that might still be applicable for your environment.
