The output shows the local membership partition list on the server where
you are running mprepair. It then compares this list with the lists located
on the disks containing the membership partitions. The output also
includes the device database records for the disks containing the
membership partitions. Following is an example.
###################################################################
Local membership partition list:
-------------------------------------------------------------------
Membership partition list --
UID/Part:20:00:00:04:cf:13:33:12::0/1 Local Path:\\.\Global\psd1p1
Status:OK (active) Size:8001Kb
These membership partitions contain a membership partition list
which matches the local membership partition file list:
UID/Part:20:00:00:04:cf:13:33:12::0/1

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.
