Search the SAN for membership partitions. To search the SAN for all partitions that
appear to be membership partitions, enter 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, Matrix Server 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membership list might become out of date.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. Enter the
following command:
mprepair --resilver <uuid/partno>
<uuid> is the UUID for the device and <partno> 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.
The resilver operation synchronizes all other membership partitions and the local
membership partition list.
Repair a membership partition. This command resilvers the specified membership
partition.
mprepair --repair [--force] <uuid/partno>
