Veritas Storage Foundation 5.1 SP1 for Oracle RAC Administrator"s Guide (5900-1512, April 2011)

Note: If multiple clusters share the same CP server, you must perform this
replacement procedure in each cluster.
You can use the vxfenswap utility to replace coordination points when fencing is
running in customized mode in an online cluster, with vxfen_mechanism=cps.
The utility also supports migration from server-based fencing
(vxfen_mode=customized) to disk-based fencing (vxfen_mode=scsi3) and vice
versa in an online cluster.
However, if the SF Oracle RAC cluster has fencing disabled (vxfen_mode=disabled),
then you must take the cluster offline to configure disk-based or server-based
fencing.
See Deployment and migration scenarios for CP server on page 56.
You can cancel the coordination point replacement operation at any time using
the vxfenswap -a cancel command.
See About the vxfenswap utility on page 122.
