3.4.0 Matrix Server Command Reference

Chapter 1: PolyServe Matrix Server Commands 9

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.

NOT FOUND. The mprepair utility cannot find the device containing the

membership partition.

INACCESSIBLE. The mprepair utility cannot access the device containing the

membership partition.

CORRUPT. The partition is not valid.

MISMATCH. The membership partition is valid but its MP list does not match

the server’s local MP list.

If the status is

NOT FOUND or INACCESSIBLE, there may be a problem with

the disk or with another SAN component. When the problem is repaired, the

status should return to

OK.

If the status is

CORRUPT, you should 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.

If the status is

MISMATCH, you will need to determine which membership

partitions are correct (the partitions specified in the local MP list, or the

partition labeled

MISMATCH) and resilver accordingly.

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 matrix, you may want

to either remove them or mark them as inactive.

A matrix could have an old membership partition if the disk containing it

becomes inaccessible and you then add another partition in its place.
