partitions. Resilvering takes place automatically when a change is made to the device
naming database or when you add, remove, or replace a membership partition.
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membership list might become out of date.
The --resilver operation requires that you specify a good membership partition.
The other membership partitions are then resilvered from that partition. Type the
following command:
mprepair --resilver UID/PART#
UID is the UID for the device and PART# is the number of the partition on the device.
NOTE:
If you resilver from a partition that has a status of RESILVER, 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.
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 PART# 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#
