The resilver operation synchronizes all other membership partitions and

the local membership partition list.

Repair a Membership Partition. This command resilvers the specified

membership partition.

mprepair --repair [--force] <uuid/partno>

indicates the membership partition to be resilvered. <uuid>

is the UUID for the device and <partno> is the number of the partition on

the device.

The membership partition is resilvered from a known valid membership

partition. Without the --force option, the command will fail if mprepair

cannot find two valid membership partitions to use as a source for the

resilver operation. The --force option overrides this requirement and

causes the resilver operation to take place.

Inactivate a Membership Partition. To inactivate membership partitions

that are marked as active but are not part of the current set defined by the

membership partition list, type the following command:

mprepair --inactivate_mp <uuid/partno>

<uuid> is the UUID for the device and <partno> is the number of the

partition on the device.

This option is useful if the matrix includes old membership partitions that

are marked active or if you want to import a disk that contains an active

membership partition.

Clear the Host Registry. The --clear_hr option removes all entries from

the server registry. This command should be used only under the

direction of HP Support.

Reset the Cluster-ID. When a matrix is created, it is assigned a Cluster-ID

that is used internally to identify the matrix. This ID is stored in the

membership partitions. If the steps for performing matrix configuration

operations or matrix upgrades are not followed precisely, it is possible for

the Cluster-ID to become out-of-sync among the membership partitions,

preventing Matrix Server from starting. This condition is unlikely;

however, if Matrix Server cannot be started on any server in the matrix,
