Sun Cluster System Administration Guide for Solaris OS

ProcedureHow to Unmonitor a Disk Path

Use this procedure to unmonitor a disk path.

Caution – Caution –

DPM is not supported on nodes that run versions that were released prior to Sun Cluster 3.1 10/03 software. Do not use DPM commands while a rolling upgrade is in progress. After all nodes are upgraded, the nodes must be online to use DPM commands.

  1. Become superuser on any node in the cluster.

  2. Determine the state of the disk path to unmonitor.

    # scdpm -p [all:] disk path

    Prints a detailed listing of the current status of a specified disk path


    Displays all monitored and unmonitored disk paths

  3. On each node, unmonitor the appropriate disk paths.

    # scdpm -u  node:disk path

    Refer to Table 4–5 for naming conventions for the node:disk path argument.

Example 4–23 Unmonitoring a Disk Path

The following example unmonitors the schost-2:/dev/did/rdsk/d1 disk path and prints disk paths with status for the entire cluster.

# scdpm -u schost-2:/dev/did/rdsk/d1
# scdpm -p all:all 
	     schost-1:/dev/did/dsk/d4   Ok
	     schost-1:/dev/did/dsk/d3   Ok
	     schost-2:/dev/did/dsk/d4   Fail
	     schost-2:/dev/did/dsk/d3   Ok
	     schost-2:/dev/did/dsk/d1   Unmonitored
	     schost-2:/dev/did/dsk/d6   Ok
