MAP 5700: Repair verification helps you to verify that field-replaceable units (FRUs) that you exchange for new FRUs, or
repair actions that are completed solve all the problems on the
SAN Volume Controller
.
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 exist
on the machine.
Procedure
-
Are the Power LEDs on all the nodes on?
-
(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
SAN Volume Controller
application for
the system you repair, 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 you return 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 you return to this MAP.
If any MDisks show
a status of excluded, include MDisks before you return to this
MAP.
Go to MAP 5000: Start.
- YES
- Go to step 4.
-
(from step 3)
Using the
SAN Volume Controller
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
SAN Volume Controller
, a number of volumes are
showing a status of offline. Volumes are held offline if
SAN Volume Controller
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 be 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 be written to the disk, so its state cannot be verified. Your
site procedures 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.

(from step 4)
You successfully repair the
