Veritas Storage Foundation 5.1 SP1 Cluster File System Administrator"s Guide (5900-1738, April 2011)

For server-based fencing, use the vxfenswap -a cancel command to cancel
the vxfenswap operation.
Replacing I/O fencing coordinator disks when the cluster is
online
Review the procedures to add, remove, or replace one or more coordinator disks
in a cluster that is operational.
Warning: The cluster might panic if any node leaves the cluster membership before
the vxfenswap script replaces the set of coordinator disks.
To replace a disk in a coordinator diskgroup when the cluster is online
1
Make sure system-to-system communication is functioning properly.
2
Make sure that the cluster is online.
# vxfenadm -d

Import the coordinator disk group.
The file /etc/vxfendg includes the name of the disk group (typically,
vxfencoorddg) that contains the coordinator disks, so use the command:
# vxdg -tfC import ‘cat /etc/vxfendg‘
where:
-t specifies that the disk group is imported only until the node restarts.
-f specifies that the import is to be done forcibly, which is necessary if one
or more disks is not accessible.
-C specifies that any import locks are removed.
