Really its very urgent i have to handover the server in next 12 hours.
Sucks to be you:)
OTOH, I am in a similar boat and have different hardware across a two cluster and I choose to perform the safest way I could think to fence with the hardware I have, I wrote a Perl script to drop the ifAdminStatus of the port that the data runs over on my switch. Aside from power fencing with a separate device, this is pretty reliable (using drbd, so no fabric switching options).
I have another nic for mgmt that uses iptables to make sure only ssh runs through it.
I had to make my own, as the older fence_ifmib didn't do snmpv3, and the newer one uses a myriad of python deps that aren't in 5.4, but scheduled for 5.5.
Hit me offllist if you like.
