Chapter 2: HP Clustered File System Commands 19

Search the SAN for Membership Partitions. To search the SAN for all

partitions that appear to be membership partitions, type this command:

mprepair --search_mps

The output includes each membership partition found by the search and

specifies whether it is active or inactive. The output also includes the

membership list on the disk containing the partition and the database records

for the partitions.

Resilver Membership Partitions. Typically, HP Clustered File System writes

data to one membership partition and then copies, or resilvers, that data to

the other membership 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corrupt or a local membership list might become out of date.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 PA RT # 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#

1 2 ... 25 26 27 28 29 30 31 32 33 34 35 ... 140 141
