Firmware updates

Attention:
ESM firmware upgrades. Save the DS4000 storage subsystem profile and all
configuration (*.cfg) files to a server disk that will remain accessible in the event of
a DS4000 storage configuration failure. Do not save these files only to a LUN in the
DS4000 Storage Subsystem.
To ensure the optimal operation of the DS4000 storage subsystem and its attached
storage expansion enclosures, the storage expansion enclosure ESM firmware, the

configuration by completing the following steps:
a. Check all LEDs on each component in the storage expansion enclosures.
Ensure that all the LEDs show normal status. For more information on LED
status for storage expansion enclosures, see "Checking the LEDs" on page
59 or the Installation, User's, and Maintenance Guide for your DS4000
storage expansion enclosure.
b. Check all LEDs on each component in the storage subsystem. Ensure that
all the LEDs show normal status. For information about LED status, see
"Solving problems" on page 101.
c. Open the DS4000 Storage Manager Subsystem Management Window, and
display the Physical View for the configuration.
The status for each component will be either Optimal or Needs Attention.
d. Review the status of the configuration components shown in the Subsystem
Management Window by selecting the appropriate component button for
each storage subsystem.

v Yes — End of procedure.
v No — Go to step 9.
a. Run the DS4000 Storage Manager Recovery Guru by selecting the
Recovery Guru toolbar button in the Subsystem Management Window.
b. Complete the recovery procedure.
If the Recovery Guru directs you to replace a failed component, use the
individual LEDs on the storage subsystem to locate the specific failed
component. For troubleshooting procedures, see Chapter 6, "Hardware
maintenance," on page 101.
c. When the recovery procedure is completed, select Recheck in the Recovery
Guru. This action reruns the Recovery Guru to ensure that the problem has
been corrected.
d. If the problem persists, contact your IBM service representative.
