■ If the cluster-wide attribute “UseFence” is set to SCSI3, reset the value to
NONE in the /etc/VRTSvcs/conf/config/main.cf file.
■ On each node, edit the /etc/vxfenmode file to configure I/O fencing in
disabled mode.
# cat /etc/vxfenmode
vxfen_mode=disabled
■ Stop I/O fencing on each node:
# /sbin/init.d/vxfen stop
