10. Diagnose and correct the fault by completing the following steps:
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
DS4000 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:

storage subsystem to completely power up. A storage subsystem can take up
to 10 minutes to power on and up to 15 minutes to complete its controller
battery self-test. During this time, the indicator lights on the front and back of
the module blink intermittently.
8. Determine the status of all storage subsystems and components in 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
73 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 125.
c. Open the DS 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.
9. Are the LEDs indicating normal operation, and is the status Optimal on all the
configuration components?
v Yes — End of procedure.
v No — Go to step 10.
a. Run the DS 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 125.
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.
Save the storage subsystem profile before performing any controller or
