MAP 5700: Repair verification

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

  1. Are the Power LEDs on all the nodes on?
    NO
    Go to MAP 5000: Start.
    YES
    Go to step 2.
  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.
  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.
  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.
  5. (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.

  6. (from step 4)

    You successfully repair the SAN Volume Controller .
