We have 6 guest OS (redhat 6.3) on 3 physical machine running VMware ESX5.0,each physical machine has 2 VMs.
And SFCFSHA has been installed.
The fencing disks are three 1GB LUN from physical arrays via VMware RDM physical mode.
but vxfentsthdw test shows:
Testing quanziweb01 /dev/vx/rdmp/ibm_ds8x000_0088 quanziweb02 /dev/vx/rdmp/ibm_ds8x000_0088

Verify registrations for disk /dev/vx/rdmp/ibm_ds8x000_0088 on node quanziweb02 Failed
Unregistration test for disk failed on node quanziweb02.
Unregistration from one node is causing unregistration of keys from the other node.
Disk is not SCSI-3 compliant on node quanziweb02.
Execute the utility vxfentsthdw again and if failure persists contact
the vendor for support in enabling SCSI-3 persistent reservations
================================================================================
I'm sure that the three 1GB LUN from the disk array support SCSI-3 persistent reservations IF used in physical machines.
But why they do not support SCSI-3 PR when used in VMware ESX virtual machines?
Is there any up-to-date official guide for configuring I/O fencing for VCS/CFS on VMware ESX?
Thanks!
