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.
The DS5100 and DS5300 spins up all the drives in the storage expansion
enclosures during the startup process.
6. 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 the
Installation, User’s, and
Maintenance Guide
for your 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
“Checking the LEDs” on page 143.
c. Open the DS Storage Manager Subsystem Management window, and
display the Physical View for the configuration.
The status for each component is 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.
7. Are the LEDs indicating normal operation, and is the status Optimal on all the
configuration components?
v
Yes – End of procedure. Replace front bezel, as described in “Removing and
replacing the front bezel” on page 130.
v
No – Go to step 8.
8. Diagnose and correct the fault by completing the following steps:
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 failed component.
(For procedures to replace a failed component, see Chapter 5, “Replacing
components,” on page 167.)
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.
Turning off the storage subsystem
Attention:
Except in an emergency, never turn off the power if any storage
subsystem’s Needs Attention LEDs are on. Correct the fault before you turn off the
power. Use the DS Storage Manager client and the Needs Attention LEDs to check
the overall status of the storage subsystem and its components. All LEDs should be
green on the front of the storage subsystem. If they are not, use the DS Storage
Manager client to diagnose the problem (see “Monitoring status through software”
on page 140). This ensures that the storage subsystem will power up correctly later.
The storage subsystem is designed to run continuously, 24 hours a day. After you
turn on the storage subsystem, do not turn it off except in the following situations:
