created later on must be at least 2 GB in size. The minimum size for a

membership partition is 100 MB.

Export Configuration Changes

When you change the membership partition configuration with

mxmpconf, it updates the membership list on the local server. It also

updates the lists on the disks containing the membership partitions

specified in the local MP file.

When you exit mxmpconf, you will be asked whether you want to export

the new membership configuration to the other servers in the matrix. This

step updates the local MP files on those servers.

Repair Menu 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.

NOTE: When you exit the Repair menu, mxmpconf checks the number of

membership partitions that are in effect after your changes. If you

have added or removed membership partitions and there are now

only two membership partitions, you will be returned to the

Repair menu so that you can either add the third membership

partition or remove one of the existing partitions.

Display Membership Partitions. The Display option lists information

about membership partitions and can also copy the data to a file. The

option shows the local membership partition list on the server where you

are running mxmpconf. It then compares this list with the lists located on

the disks containing the membership partitions. In the following

example, the lists match. The output also includes the device database

records for the disks containing the membership partitions.
