3.6.0 Matrix Server 3.6.0 Administration Guide (5697-7081, December 2007)

Chapter 19: SAN Maintenance 240

• locked (lock is corrupt, will repair)

The host on which mxsanlk was run holds the lock. The SANlock was

corrupted but will be repaired.

If a membership partition cannot be accessed, use the mx config mp set

command or the mprepair utility to correct the problem.

Depending on the status of the SDMP process, when you invoke mxsanlk

you may see one of the following messages:

Checking for SDMP activity, please wait...

Still trying...

The SDSMP is inactive at this host.

The SDMP appears to be inactive at this host.

If the SDMP process is not responding on the host, wait a few seconds

and retry the command. If the command continues to fail, shut down the

matrix and then restart it. This step should restart the SDMP process. If

you continue to have problems, contact HP Support.

Manage Membership Partitions

Matrix Server provides the following utilities for managing membership

partitions, including adding new partitions, replacing existing partitions,

and resilvering corrupt partitions.

• The Storage Settings tab on the Configure Matrix window contains

options to add, repair, or replace membership partitions. These

options can be used while the matrix is either online or offline.

However, when the matrix is running, only the operations listed

below can be performed. The remove option can be used only when

Matrix Server is offline on all nodes.

•The mx config mp commands can be used to add, repair, or replace

membership partitions. These commands can be used while the

matrix is either online or offline, with the limitations described below

for online operations.

•The mprepair command can be used to display information about

membership partitions and to perform all operations affecting

membership partitions. Matrix Server must be offline on all nodes

when this command is used.
