If a membership partition cannot be accessed, use the mprepair program to

correct the problem.

When you invoke mxsanlk, it checks for the Storage Device Monitor Pulse

(SDMP) process. This process is responsible for grabbing and maintaining the

locks on the membership partitions. Depending on the status of the SDMP

process, 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 PolyServe Technical Support.
