intervention. After the air has cooled, the power supplies should turn on
automatically. If the power supplies restart automatically, the controllers will
reset and return to normal operation.
7. Did the power supplies restart automatically?
v Yes - Go to step 9.
v No - Go to step 8.
8. Turn off the power switch on each controller in the storage subsystem and
then power off all connected storage expansion enclosures. Wait 1 minute and
then turn on power to all connected storage expansion enclosures.
While the storage expansion enclosure powers up, the LEDs on the front and
the back of the module blink intermittently. Depending on your configuration,
the storage expansion enclosure can take between 20 seconds and several
minutes to power on.
9. Turn on both power switches on the back of the storage subsystem. See
Figure 61 on page 82.
A storage subsystem can take 10 seconds to power on and up to 15 minutes
for the battery self-test to complete. During this time, the LEDs on the front
and the back of the modules blink intermittently.
completing the following steps:
a. Note the status of the LEDs on the front and back of each module.
A green LED indicates a normal status; amber LEDs indicate a hardware
fault.
b. Open the Subsystem Management window for the storage array.
c. Select the appropriate components button for each module in the Physical
View of the Subsystem Management window to view the status of its
components.
The status for each component is either Optimal or Needs Attention.
module component?
v Yes - Go to step 13.
v No - Go to step 12.
a. To run the Recovery Guru, select 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, locate and
troubleshoot that component. See "Checking the LEDs" on page 88.
c. When the procedure is completed, rerun the Recovery Guru to ensure that
the problem has been corrected by selecting Recheck in the Recovery
Guru.
d. If the problem persists, contact IBM Customer and Technical Support.
