Before any planned system shutdown or after any system additions, removals, or
modifications (including firmware updates, logical drive creations, storage
partitioning definitions, hardware changes, and so on), save the storage subsystem
profile as explained in the DS Storage Manager guide for your operating system.
Save the profile in a location other than the logical drives created for the DS5020.
Always refer to the readme that is included with the DS5020 storage subsystem
firmware package (whether the firmware is accessed by the Web or DVD) for any
special requirements or restrictions that apply to that particular firmware version.
See “Finding DS5020 and DS4000-family readme files” on page xxiv to learn how
to access the readme files on the Web.
Note: Make sure that you install the DS Storage Manager event monitoring service
to enable continuous monitoring of the status of the storage subsystem. For
more information about the importance of this information, see “Monitoring
status through software.”
Monitoring status through software
Use the DS Storage Manager client to monitor the status of the storage subsystem.
Run the software constantly, and check it frequently.
Notes:
1. Youcan only monitor storage subsystems that are within the management
domain of the storage-management software.
2. If you have not installed the DS Storage Manager Event Monitor service as part
of the storage-management software installation, the DS Storage Manager
Enterprise Management window must remain open. (If you close the window,
you will not receive any alert notifications from the managed storage
subsystems.)
For more information, see the Enterprise Management online Help.
Important: Refer to the IBM System Storage DS Storage Manager Version 10
Installation and Host Support Guide for the applicable operating system
for instructions on how to install the DS Storage Manager host
software.
In addition, to download the latest version of the DS Storage Manager
host software, the DS5020 storage subsystem controller firmware and
NVSRAM, and the latest storage expansion enclosure ESM firmware,
go to the following Web site:

The DS Storage Manager client provides the best way to diagnose and repair
storage-server failures. The software can help you do the following:
vDetermine the nature of the failure
vLocate the failed component
vDetermine the recovery procedures to repair the failure
Although the storage subsystem has Needs Attention LEDs, these LEDs do not
necessarily indicate which component has failed or needs to be replaced, or which
type of recovery procedure you must perform. In some cases (such as in the case
