Firmware updates

Attention:
ESM firmware upgrades. Save the DS5020 storage subsystem profile and all
configuration (*.cfg) files to a server disk that will remain accessible in the event of
a DS5020 storage configuration failure. Do not save these files only to a LUN in the
DS5020 storage subsystem.
For optimal operation of the DS5020 and its attached storage expansion
enclosures, the storage expansion enclosure ESM firmware, the DS5020 controller
firmware, the hard drive firmware, and the NVSRAM (for controllers only) must be
up to date. Go to the following Web site to get the latest updates.
http://www.ibm.com/systems/support/storage/disk
Always check the readme files that are included with the firmware packages for the
most up-to-date information about firmware prerequisites, firmware update
instructions, and host I/O restrictions, if any. Apply the necessary updates before
configuring the storage subsystem arrays and logical drives. Subscribe to My
Support for automatic notifications of firmware or Storage Manager software
updates or any important information about your storage subsystems (see "Product
updates and support notifications" on page 6).
Attention:
Manager software package for any limitations, subsystem firmware prerequisites, or
download-sequence information. For example, the controller firmware code might
require the storage expansion enclosure ESM firmware to be upgraded first to a
particular version, or the controller firmware download might require the halting of
I/Os to the DS5020 logical drives. Failure to observe the limitations, prerequisites,
and dependencies in the readme file might result in a loss of data access. See
"Finding DS5020 and DS4000-family readme files" on page xxv to learn how to
access the DS5020 readme files on the Web.
Unless the readme file contains special requirements for the sequence in which you
upgrade firmware, perform firmware upgrades in the following sequence:
1. ESM firmware for the storage expansion enclosures
2. Controller firmware
3. Controller NVSRAM
4. Drive firmware

Troubleshooting the storage subsystem

The DS Storage Manager is the best way to monitor the storage subsystem,
diagnose a problem, and recover from a hardware failure. Run the DS Storage
Manager continuously, and frequently check the configuration status.
Use the following procedure to check the status of and identify a problem with the
storage subsystem. If a problem has occurred, use the DS Storage Manager client
software and the LEDs on the storage subsystem to help locate a failed component.
1. Open the Subsystem Management window.
