fence_scsi on VMware vCenter / ESXi fails when a cluster node is shutdown from the host in RHEL 5 or 6 or 7

Solution Verified - Updated -


  • When shutting down a cluster node from vCenter, the node fails to be fenced by fence_scsi
  • When a VMware cluster node is shutdown gracefully, its SCSI registrations and reservations disappear on their own
  • When simulating a failure scenario where the active node providing service is shut down forcefully, the backup node does not take over the service.


  • Red Hat Enterprise Linux (RHEL) 5 or 6 or 7 with the High Availability Add On
  • VMware vCenter / ESXi 5.0 or 5.1
  • VMs using shared storage presented via Virtual Disk Files (VMDKs) or Raw Device Mapping (RDM)
  • SCSI Persistent Reservation Fencing (fence_scsi)
