Veritas Storage Foundation 5.1 SP1 Cluster File System Administrator"s Guide (5900-1738, 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 SFCFS 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 105.
You can cancel the coordination point replacement operation at any time using
the vxfenswap -a cancel command.
See “About the vxfenswap utility” on page 87.
