mprepair --display_mplists
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.
root@s5 ~]# mprepair --display_mplists
###################################################################
Local membership partition list:

These membership partitions contain a membership partition list
which matches the local membership partition file list:
UID/Part:6-6005-08B4-0008-A218-0000-C000-002E-0000/1
UID/Part:6-6005-08B4-0008-A218-0000-C000-0031-0000/1
UID/Part:6-6005-08B4-0008-A218-0000-C000-0036-0000/1
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 Scalable NAS 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membership list might become out of date.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. Run the
following command:
mprepair --resilver <uuid/partno>
