To fix this problem, use the --inactivate_mp option (described under

“mprepair Options” below) to change the state of the membership

partition to “inactive.” You can then import the disk into the matrix.

Sizes for Membership Partitions

Matrix Server stores the size of the smallest membership partition that

was created during the Matrix Server installation. When you add or

replace a membership partition, the new partition must be at least as

large as that original partition. For example, if you originally created

10-MB, 11-MB, and 12-MB membership partitions, any membership

partitions created later on must be at least 10 MB in size.

Export Configuration Changes

When you change the membership partition configuration with

mprepair, 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.

After making changes with mprepair, you will need to export the

configuration to the other servers in the matrix. To do this, start Matrix

Server on the server where you ran mprepair and then connect to the

PolyServe Management Console. Select File > Configure to display the

Configure Matrix window and go to the Matrix Wide Configuration tab.

Select the other servers in the Address column and then click Export.

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
