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 expansion
enclosure, you might have to cycle the power on the DS3500 storage
subsystem and all remaining expansion enclosures that are connected to the
storage subsystem. Contact your IBM technical-support representative before
you power-off any attached expansion enclosures.
5. Check the LEDs on the front and the rear of the 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.”
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.
Checking the LEDs
The LEDs indicate the status of the storage subsystem and components. Green
LEDs indicate a normal operating status; amber LEDs indicate a possible failure; a
blue LED on a component indicates that it is safe to remove the component.
The DS3500 also has a blue system locator LED that is lit when the menu function
is selected in the Subsystem Management window, causing the Locate command to
be sent to the DS3500.
Check all the LEDs on the front and rear of the storage subsystem when you turn
on the power. During power-on, the LEDs flash intermittently as the storage
subsystem and components complete the power-on process. In addition to checking
for faults, you can use the LEDs on the front of the storage subsystem to determine
whether the drives are responding to I/O transmissions from the host.
Power-supply LEDs
This section describes the primary LEDs on the DS3500 power supplies.
