Chapter 19: SAN Maintenance 247
--reuse
Allow disks that contain existing volume information to be reused. (The
existing data is destroyed.)
Repair a Membership Partition
This command resilvers the specified membership partition.
mx config mp repair [--reuse] <uuid>
The --reuse option allows disks that contain existing volume information
to be reused. (The existing data is destroyed.) This option is available only
when the cluster is offline.
Replace a Membership Partition
To replace a membership partition, use this command:
mx config mp set <uuid> <uuid> <uuid>
Specify the UIDs for the new membership partition and for the two
existing membership partitions that will be retained.
The mprepair Utility
The mprepair utility is invoked from the operating system prompt.
NOTE: HP Clustered File System cannot be running when you use
mprepair. To stop the cluster, issue the command net stop
matrixserver from the Command Prompt.
Membership Partition File
Each server in the cluster 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
each server in the cluster have the same view of where the partitions are
located.
However, it is possible for these views to get out of sync if changes to the
membership partition configuration are made when all servers are not
accessible. Therefore, before a server can negotiate for control of the SAN,
it must have a local MP list that matches the membership lists stored on
each of the membership partitions, and each membership partition must
