MAP 5700: Repair verification helps you to verify that field-replaceable units
(FRUs) that you have exchanged for new FRUs, or repair actions that have
been done have solved all the problems on the IBM Spectrum Virtualize™.
Before you begin
If you are not familiar with these maintenance analysis
procedures (MAPs), first read Using the maintenance analysis procedures.
You might have been sent here because you performed a repair
and want to confirm that no other problems exists on the machine.
Procedure
- Are the Power LEDs on all the nodes on? For more information about this LED,
see Power LED.
- NO
- Go to MAP 5000: Start.
- YES
- Go to step 2.
- (from step 1)
Are all the nodes displaying Cluster: or is the node status LED on?
- NO
- Go to MAP 5000: Start.
- YES
- Go to step 3.
- (from step 2)
Using the IBM Spectrum Virtualize application for the system you have just repaired, check the status of all configured managed disks (MDisks).
Do all MDisks have a status of online?
- NO
- If any MDisks have a status of offline, repair the MDisks. Use the problem determination procedure for the disk controller to repair the MDisk faults before returning to this MAP.
If any MDisks have a status of degraded paths or degraded ports, repair any storage area network (SAN) and MDisk faults before returning to this MAP.
If any MDisks show a status of excluded, include MDisks before returning to this MAP.
Go to MAP 5000: Start.
- YES
- Go to step 4.
- (from step 3)
Using the IBM Spectrum Virtualize application on the repaired system, check the status of all configured volumes.
Do all volumes have a status of online?- NO
- Go to step 5.
- YES
- Go to step 6.
- (from step 4)
Following
a repair of the IBM Spectrum Virtualize,
a number of volumes are showing a status of offline. Volumes will
be held offline if IBM Spectrum Virtualize cannot
confirm the integrity of the data. The volumes might be the target
of a copy that did not complete, or cache write data that was not
written back to disk might have been lost. Determine why the volume
is offline. If the volume was the target of a copy that did not complete,
you can start the copy again. Otherwise, write data might not have
been written to the disk, so its state cannot be verified. Your site
procedures will determine how data is restored to a known state.
To bring the volume online, you must move all the offline disks
to the recovery I/O group and then move them back to an active I/O
group.
Go to MAP 5000: Start.

have successfully repaired the IBM Spectrum Virtualize.
