• Hello Sir,

  I have installed VMware Workstation 10 & on top of that I have installed ESXi 5.5 & under that I have created 2 RHEL-7.3 VM's

  I have configured fencing in same way, but it didn't worked for me. Please see below Logs of my Cluster;

  # pcs config

  Stonith Devices:
  Resource: vmfence1 (class=stonith type=fence_vmware_soap)

• Physical system in the sense — I have created a VM and its a passthrough. so this which type of fence device I need to create.

• Hi,
  If I am using a physical system at that time which stonith /fence device I need to create?
