  1. Create a new lun and map it to the members of the cluster.
  2. mkfs the new disk.
  3. Create the mount point on both servers.
  4. Add the new disk the /etc/cluster/cluster.conf under the resources and service.
  5. Dont forget to raise the config_version.
  6. Update the cluster by running: ccs_tool update /etc/cluster/cluster.conf
