Adding disks from a recovered site to the coordinator diskgroup

In a campus cluster environment, consider a case where the primary site goes

down and the secondary site comes online with a limited set of disks. When the

primary site restores, the primary site's disks are also available to act as

coordinator disks. You can use the vxfenswap utility to add these disks to the

coordinator diskgroup.

To add new disks from a recovered site to the coordinator diskgroup

Make sure system-to-system communication is functioning properly.

Make sure that the cluster is online.
