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] UID/PART#
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 PART # is the number of the partition on
the device.
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
