Search the SAN for Membership Partitions. To search the SAN for all
partitions that appear to be membership partitions, type this command:
mprepair --search_mps
The output includes each membership partition found by the search and
specifies whether it is active or inactive. The output also includes the
membership list on the disk containing the partition and the database
records for the partitions.
Resilver Membership Partitions. Typically, HP Clustered File System
writes data to one membership partition and then copies, or resilvers, that
data to the other membership partitions. Resilvering takes place
automatically when a change is made to the device naming database or
when you add, remove, or replace a membership partition.
However, in certain situations you may need to perform the resilver
operation manually. For example, a membership partition might become
corrupt or a local membership list might become out of date.
The --resilver operation requires that you specify a good membership
partition. The other membership partitions are then resilvered from that
partition. Type the following command:
mprepair --resilver UID/PART#
UID is the UID for the device and PART # is the number of the partition on
the device.
NOTE: If you resilver from a partition that has a status of RESILVER, the
operation may initialize partitions that are not currently
membership partitions; any existing data on those partitions will
be overwritten. Use the --display_mplists option to see the
membership partition lists for the current membership partitions.
