4.1.0 HP PolyServe Software command reference guide (T5392-96071, October 2010)

matrix has a membership partition file, which is called the “local MP list.” Each SAN
disk containing a membership partition also has its own list of the membership
partitions. Under normal operations, these lists should all match.
The output from --get_current_mps contains a record for each membership
partition. Following is a sample record.
20:00:00:04:cf:13:33:12::0/1 OK 8001Kb active
The first field contains the disk UUID followed by a slash and the partition number
(partition 1 in the above example). The second field reports the status of the
membership partition. The third field specifies the size of the membership partition,
and the last field reports whether the membership partition is active or inactive.
The status reported in the second field will be one of the following:
OK. The membership partition is included in the local membership partition list. This
is the normal status.
FENCED. The server has been fenced and cannot access the SAN. Start Matrix Server
if it is not running or reboot the server.
NOT_FOUND. The mprepair utility cannot find the device containing the membership
partition. There may be a problem with the disk or with another SAN component.
When the problem is repaired, the status should return to OK.
INACCESSIBLE. The mprepair utility cannot access the device containing the
membership partition. There may be a problem with the disk or with 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
resilver accordingly.
CID_MISMATCH. The Cluster-ID is out-of-sync among the membership partitions and
must be reset. See “Reset the cluster ID” under mprepair options, page 28.
