Attention: Failure to observe the limitations, prerequisites, sequences, and
dependencies in the readme file might result in a loss of data access.
Unless the readme file contains special requirements for the sequence in which you
upgrade firmware, perform firmware upgrades in the following sequence:
1. ESM firmware for the storage expansion enclosures
2. Controller firmware
3. Controller NVSRAM
4. Drive firmware
Troubleshooting the storage subsystem
The DS3000 Storage Manager software is the best way to monitor the storage
subsystem, diagnose a problem, and recover from a hardware failure. Run the
DS3000 Storage Manager continuously, and frequently check the configuration
status.
To check the status of and identify a problem with the storage subsystem, complete
the following steps. If a problem has occurred, use the DS3000 Storage Manager
software and the LEDs on the storage subsystem to help locate a failed component.
1. Open the Subsystem Management window.
2. Click the Summary tab, and view the status of the storage subsystem.
3. Does any storage subsystem have a Needs Attention status?
v Yes: Go to step 4.
v No: All components are Optimal. Go to step 5.
4. Click Recovery Guru on the toolbar. Perform the procedure in the Recovery
Guru to correct the problem. The Recovery Guru might direct you to replace the
failed component. If so, go to step 5.
Attention: If the fault requires you to power-off an attached storage expansion
enclosure, you might have to cycle the power on the DS3200 storage
subsystem and all remaining storage expansion enclosures that are connected
to the storage subsystem. Contact your IBM technical-support representative
before you power-off any attached storage expansion enclosures.
5. Check the LEDs on the front and the rear of the storage expansion enclosure. A
green LED indicates a normal status; an amber LED indicates a hardware fault.
6. Is an amber LED lit?
v Yes: Locate and troubleshoot the failed components. See “Checking the
LEDs” on page 52.
v No: You are finished with this procedure. If you are still experiencing a
problem with the storage subsystem, create, save, and print a storage
subsystem profile, and contact your IBM technical-support representative for
assistance. When the recovery procedure is completed, select Recheck in
the Recovery Guru to run the Recovery Guru again to make sure that the
problem is corrected.
