mprepair.exe – repair membership partitions

Synopsis

bin\mprepair

Description

The mprepair utility can be used to repair any problems if a failure causes

servers to have inconsistent views of the membership partitions. This utility is

invoked from the operating system prompt.

NOTE: PolyServe Matrix Server cannot be running when you use mprepair.

To stop the matrix, issue the command net stop matrixserver from the

Command Prompt.

View Membership Partitions and Their Status

To view the current membership partitions, type the following command at

the operating system prompt:

mprepair --get_current_mps

This command lists the current membership partitions according to the

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

Each server in the matrix has a membership partition file, which is called the

“local MP list.” Each SAN disk containing a membership partition also has its

own list of the membership partitions. Under normal operations, these lists

should all match.

The output from --get_current_mps contains a record for each membership

partition. Following is a sample record:

20:00:00:04:cf:13:33:12::0/1 OK 8001Kb active

The first field contains the disk UUID followed by a slash and the partition

number (partition 1 in the above example). The second field reports the status

of the membership partition. The third field specifies the size of the

membership partition, and the last field reports whether the membership

partition is active or inactive.
