Adding or Removing Coordinator Disks

Before adding coordinator disks, verify the disks support SCSI-3 persistent reservations. See Using the vxfentsthdw Utility for instructions.

1. Log in as root on any cluster node.
2. Import the coordinator disk group. The file /etc/vxfendg includes the name of the disk group containing the coordinator disks. Type:
     # vxdg -tfC import 'cat /etc/vxfendg'

   where:

   -t specifies that the disk group is imported only until the system reboots.

   -f specifies that the import is to be done forcibly, which is necessary if one or more disks is inaccessible.

   -C specifies any import blocks are removed.

3. To add disks to, or remove them from, the disk group, use the VxVM disk administrator utility, vxdiskadm.
4. After disks are added or removed, deport the disk group:
     # vxdg deport 'cat /etc/vxfendg'
5. Reboot each system in the cluster to make the coordinator disks accessible:
