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 SAN Volume Controller.
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.
Perform the following steps to verify your repair:
- Are the Power LEDs
on all the SAN Volume Controller nodes
on?
For more information about this LED, see Power LED.- NO
- Go to MAP 5000: Start.
- YES
- Go to step 3.
- Are the Power LEDs
on all the SAN Volume Controller nodes
on?
For more information about this LED, see Power LED.- NO
- Go to MAP 5000: Start.
- YES
- Go to step 4.
- (from step 1)
Are
the Check LEDs on all SAN Volume Controller nodes
off? For more information about this LED, see Check LED.
- NO
- Go to MAP 5000: Start.
- YES
- Go to step 4.
- (from step 32)
Are all the SAN Volume Controller nodes
displaying Cluster: on the top line of the front
panel display with the second line blank or displaying a cluster name?
- NO
- Go to MAP 5000: Start.
- YES
- Go to step 5.
- (from step 4)
Using
the SAN Volume Controller application
for the cluster 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. See Determining the failing enclosure or disk controller using the CLI
to locate the disk controller with the offline MDisk. 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 6.
- (from step 5)
Using
the SAN Volume Controller application
for the cluster you have just repaired, check the status of all configured
virtual disks (VDisks).
Do all VDisks have a status of online?- NO
- Go to step 7.
- YES
- Go to step 8.
- (from step 6)
Following
a repair of the SAN Volume Controller,
a number of VDisks are showing a status of offline. VDisks will be
held offline if SAN Volume Controller cannot
confirm the integrity of the data. The VDisk 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 VDisk is offline.
If the VDisk 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 VDisks 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.
See Recovering from offline VDisks for
details on how to resolve this problem.
