mxmpconf – manage membership partitions

Synopsis

/opt/polyserve/bin/mxmpconf

NOTE: Matrix Server cannot be running when you use mxmpconf. To stop

the matrix, use the following command:

# /etc/init.d/pmxs stop

Description

The mxmpconf utility starts an ASCII interface that can be used to create a

new set of membership partitions or to repair the existing partitions

Membership partitions control access to the SAN and store the device naming

database, which includes the global device names for SAN disks imported

into the matrix. Each server in the matrix has a membership partition file,

which is called the “local MP list.” This file specifies the locations of the

membership partitions. Each membership partition also has its own MP list.

Because the membership partitions control access to the SAN, it is important

that all servers in the matrix have the same view of where the partitions are

located. The mxmpconf utility can be used to repair any problems if a failure

causes servers to have inconsistent views of the membership partitions.

For detailed information about mxmpconf, see the PolyServe Matrix Server

Administration Guide.

Setup Option

The Setup option allows you to create a new set of membership partitions.

You can select up to three SAN partitions to be used as membership

partitions. It is recommended that the partitions be on separate disks.

Repair Menu

The Repair Menu lists the current membership partitions according to the MP

file maintained on the server where you are running the utility.

Membership partitions are either active or inactive. The current membership

partitions are active. There can also be old membership partitions in the

matrix that are now inactive.
