Sun Cluster Software Installation Guide for Solaris OS

ProcedureHow to Verify the Disk Group Configuration

Perform this procedure on each node of the cluster.

  1. Become superuser.

  2. List the disk groups.

    phys-schost# vxdisk list
  3. List the device groups.

    phys-schost# cldevicegroup list -v
  4. Verify that all disk groups are correctly configured.

    Ensure that the following requirements are met:

    • The root disk group includes only local disks.

    • All disk groups and any local disk groups are imported on the current primary node only.

  5. Verify that all volumes have been started.

    phys-schost# vxprint
  6. Verify that all disk groups have been registered as Sun Cluster device groups and are online.

    phys-schost# cldevicegroup status

    Output should not display any local disk groups.

  7. (Optional) Capture the disk partitioning information for future reference.

    phys-schost# prtvtoc /dev/rdsk/cNtXdYsZ > filename

    Store the file in a location outside the cluster. If you make any disk configuration changes, run this command again to capture the changed configuration. If a disk fails and needs replacement, you can use this information to restore the disk partition configuration. For more information, see the prtvtoc(1M) man page.

  8. (Optional) Make a backup of your cluster configuration.

    An archived backup of your cluster configuration facilitates easier recovery of the your cluster configuration,

    For more information, see How to Back Up the Cluster Configuration in Sun Cluster System Administration Guide for Solaris OS.

Guidelines for Administering VxVM Disk Groups

Observe the following guidelines for administering VxVM disk groups in a Sun Cluster configuration:


If the output of the cldevicegroup status command includes any local disk groups, the displayed disk groups are not configured correctly for local-only access. Return to How to Create a Disk Group to reconfigure the local disk group.

Next Steps

Determine from the following list the next task to perform that applies to your cluster configuration. If you need to perform more than one task from this list, go to the first of those tasks in this list.
