another SAN component. When the problem is repaired, the status
should return to
OK.
CORRUPT. The partition is not valid. You will need to resilver the
partition. This step copies the membership data from a valid membership
partition to the corrupted partition.
NOTE: The membership partition may have become corrupt because it
was used by another application. Before resilvering, verify that it
is okay to overwrite any existing data on the partition.
RESILVER. The membership partition is valid but its MP list does not
match the server’s local MP list. You will need to determine which
membership partitions are correct (the partitions specified in the local MP
list, or the partition labeled
RESILVER) and then resilver accordingly.
CID_MISMATCH. The Cluster-ID is out-of-sync among the membership
partitions and must be reset. See “Reset the Cluster ID” on page 279.
Active and Inactive Membership Partitions
A membership partition can be either active or inactive. (This attribute is
reported in the last field of the record displayed by the mprepair
--get_current_mps command.) The current membership partitions
should all be active. If there are old membership partitions in the cluster,
you may want to either remove them or mark them as inactive.
A cluster could have an old membership partition if the disk containing it
becomes inaccessible and you then add another partition in its place.
When the disk access problem is corrected, the old membership partition
will still be on the disk and will be marked active.
When a membership partition is active, the disk containing the partition
cannot be imported into the cluster. You may see this situation if you
want to import a disk that was previously used by another cluster.
To fix this problem, use the --inactivate_mp option (described under
“mprepair Options” below) to change the state of the membership
partition to “inactive.” You can then import the disk into the cluster.
