1. Stop all I/O activity to the storage subsystems.
2. 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.
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
“Checking the LEDs” on page 143.
c. Open the Subsystem Management window for the configuration and display
the Physical View for the configuration.
d. Review the status of the configuration components shown in the Subsystem
Management window by selecting the appropriate component button for
each storage subsystem.
The status for each component is either Optimal or Needs Attention.
3. Are the LEDs indicating normal operation, and is the status Optimal on all the
configuration components?
v
Yes – Go to step 5.
v No – Go to step 4.
4. To diagnose and correct the fault, complete the following steps:
a. Run the 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 failed component.
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 fixed.
d. If the problem has not been fixed, contact your IBM service representative.
Do not turn off power until all problems are corrected.
5. Check the back of the storage subsystem, and verify that the Cache Active LED
is off.
If the Cache Active LED is on steady, the cache contains data. Wait for the data
to clear from cache memory before turning off the power.
6. Check the LEDs on the storage expansion enclosures to verify that all Drive
Active LEDs are on steady (not blinking).
If one or more LEDs are blinking, data is being written to or from the drives.
Wait for all Active LEDs to stop blinking.
7. Turn off the ac power switch on the back of each controller in the storage
subsystem. (Figure 88 on page 123 shows the location of the ac power switch
on a controller.)
Note: Until the power switch on each controller is turned off, power still remains
turned on for the both controllers; therefore, the seven-segment display
on each controller stays on until the power switch on each controller is
turned off.
8. Turn off both power switches on the back of each storage expansion enclosure
in the configuration.
Note: After you power off the storage subsystem, the controller remains
powered on for three to four minutes to flush any data in cache memory
to the flash memory modules.
