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, 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.
