How to Remove a Shared Disk/LUN from a Cluster

Use this procedure to remove a shared device, such as a shared disk or a LUN, from a cluster.

  1. Assume the root role or a role that provides solaris.cluster.read and solaris.cluster.modify authorization on a node in the cluster.
  2. Ensure the device is not being used by applications on the cluster.
  3. Ensure the device is not in storage resources or disk groups or zpools or /etc/vfstab on any node of the cluster.
  4. Ensure device is not added to a zone cluster.
    # clzc show
    # clzc configure
  5. After ensuring device is no longer used anywhere on the cluster, remove the device.
  6. Remove all DID references to the device.

    You must complete this step on all nodes in the cluster.

    # cldevice clear
