node1# cp -p /etc/vxfenmode /etc/vxfenmode.test
node2# cp -p /etc/vxfenmode /etc/vxfenmode.test

node1# vi /etc/vxfenmode.test
node2# vi /etc/vxfenmode.test
change line scsi3_disk_policy=raw   to   scsi3_disk_policy=dmp

check that the ssh passwordless works :
root@node1 # ssh node2

check if fencing is started :
# gabconfig -a 
should show at least port a / b / h

# vxfenconfig -l
should show raw device name

node1# vxfenswap
