However, in certain situations you may need to perform the resilver

operation manually. For example, a membership partition might become

corrupt or a local membership list might become out of date.

To resilver from a particular partition, type the following command:

mprepair --resilver UID/PART#

UID is the UID for the device and PA RT # is the number of the partition on

the device.

NOTE: If you resilver from a partition that has a status of MISMATCH,

the operation may initialize partitions that are not currently

membership partitions; any existing data on those partitions will

be overwritten. Use the --display_mplists option to see the

membership partition lists for the current membership partitions.

The resilver operation synchronizes all other membership partitions and

the local membership partition list.

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 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.
