SCSI Persistent Reservation fencing (fence_scsi) does not work in RHEL 5 or 6 with multiple ESXi VM cluster nodes running on the same host
Issue
- Does
fence_scsiwork with cluster nodes as guests on the same ESXi host? - I need to configure a fence device for ESXi VM cluster nodes.
fence_scsiworks from command line but not fromcman
