mprepair options
Matrix Server can operate with either one membership partition or three membership
partitions. To ensure that a membership partition is always available, we recommend
that you use three membership partitions.
Display Membership Partitions. To display information about membership partitions,
type the following command:
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.
###################################################################
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
