I have installed RHEV 6.5 on HOST system and using RHEV 3.3 hypervisor.
OS version: RHEV Hypervisor - 6.5 - 20141017.0.el6ev
Kernel version: .6.32 - 431.37.1.el6.x86_64
KVM version: 0.12.1.2 - 2.415.el6_5.14

RHEV-M version: rhevm-3.3.3-0.52.el6ev.noarch

I have exposed two FC disks from host to guest OS (RHEL 6.5) one from 3 PAR array and another from EVA disk array.
I am trying to use persistent reservation (iscsi) command but command is failing.

Please guide me to fix this problem.

On host (host1) persistent reservation is working but in guest system (guest1) persistent reservation command failed.

On host:
