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.

The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.

This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix B, Sun Cluster Object-Oriented Commands.

  1. Become superuser or assume a role that provides solaris.cluster.modify RBAC authorization on any node in the cluster.

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

    # cldevice status device
  3. On each node, unmonitor the appropriate disk paths.

    # cldevice unmonitor -n node disk

Example 5–47 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.

# cldevice unmonitor -n schost2 /dev/did/rdsk/d1
# cldevice status -n schost2 /dev/did/rdsk/d1

Device Instance              Node               Status
---------------              ----               ------
/dev/did/rdsk/d1             schost-2           Unmonitored
