Chapter 2: HP Clustered File System Commands 20

UID/PART# indicates the membership partition to be resilvered. UID is the

UID for the device and PA RT # 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 UID/PART#

UID is the UID for the device and PA RT # is the partition number.

This option is useful if the cluster 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 cluster is created, it is assigned a cluster ID that

is used internally to identify the cluster. This ID is stored in the membership

partitions. If the steps for performing cluster configuration operations or

cluster upgrades are not followed precisely, it is possible for the cluster ID to

become out-of-sync among the membership partitions, preventing HP

Clustered File System from starting.

This condition is unlikely; however, if HP Clustered File System cannot be

started on any server in the cluster, you can use the following command to

determine whether all membership partitions have a valid cluster ID.

mprepair --sync-clusterids

The command displays the cluster IDs found in each membership partition

and flags those partitions containing an invalid ID. You can then specify

whether you want the command to repair the partitions having a mismatched

cluster ID.
