If you are experiencing problems accessing an independent disk pool or
making it available, there may be a problem with the disk pool. Possible
problems include:
- The configuration source is corrupted. When corruption occurs, the independent
disk pool will appear to have no disk units in it. The disk pool may also
appear to have no disk units in it if it is switched to another node in a
clustered environment. Before you attempt a recovery, make sure that no other
system owns the disk pool. If you know the serial numbers of the disk units
in the independent disk pool that might need recovery, make sure you are on
the system that owns those disk units and that they show as nonconfigured.
If the configuration source is corrupted, you can select to recover the
configuration information about the configuration source. Recovering the
configuration attempts to determine the original configuration and recover
it. During this process, the independent disk pool might need to be cleared,
destroying all data on the disk units in the pool. If the disk pool needs
to be cleared, a message is displayed telling you of this and allowing you
to cancel the recovery.
- The mirrored disk unit of the configuration source is damaged. When this
happens, the mirrored configuration source becomes unknown. The disk pool
will be unavailable, and you must recover the configuration information of
an unknown configuration source before making it available. You should only
attempt to recover the state of the unknown configuration source when you
know its mirrored disk unit was active before the failures that caused the
state to become unknown.
To attempt to recover an independent disk pool, follow these steps:
- In iSeries™ Navigator,
expand My Connections (or your active environment).
- Expand any iSeries server.
- Expand Configuration and Service.
- Expand Hardware.
- Expand Disk Units.
- If the Service Tools Signon dialog box displays, sign on to service tools.
- Select Disk Pools.
- Right-click the problematic disk pool. If iSeries Navigator detects one of the
problems listed above, then Recover Configuration or Recover Unknown
Configuration Source appears in the list. If you see either of these
options, select it to continue.
- Follow the instructions on the dialog box displayed.
