Chapter 1: PolyServe Matrix Server Commands 10

When the disk access problem is corrected, the old membership partition will

still be on the disk and will be marked active.

When a membership partition is active, the disk containing the partition

cannot be imported into the matrix. You may see this situation if you want to

import a disk that was previously used by another matrix. 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

PolyServe Matrix Server stores the size of the smallest membership partition

that was created during the PolyServe 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 PolyServe

Matrix Server on the server where you ran mprepair and then select the

Configure option on the PolyServe Matrix Server Connect window. When the

Configure Matrix window appears, select the Matrix Wide Configuration tab.

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

mprepair Options

PolyServe 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
