Depending on the number of storage expansion enclosures in the configuration,
the storage subsystem might take several minutes to power up. The battery
self-test might take an additional 15 minutes. The LEDs will blink intermittently
until the storage subsystem powers up and completes the battery self-test.
Before attempting any operations, wait at least five minutes for the storage
subsystem to completely power up. A storage subsystem can take up to 10
minutes to power on and up to 15 more minutes to complete its controller
battery self-test. During this time, the indicator lights on the front and back of
the module blink intermittently.
7. 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
88 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 135.
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.
8. 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 9.
9. Diagnose and correct the fault by completing the following steps:
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 135.
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.
