As of Proxmox 5.0, there is no use for this menu. It only displays the fencing device being used by Proxmox HA. Proxmox uses a hardware watchdog and software Linux watchdog for fencing. The following screenshot shows the Fencing menu interface:

At this point, we've created a Proxmox HA group and added a VM to the group to be managed by HA. Our VM is currently in the pmx-01 node and is ready to be managed by Proxmox HA. The following screenshot shows the Status menu of HA:

As we can see, in the preceding screenshot, the Status menu shows the current state of the entire HA feature. For our example cluster, it shows the following vital information:

• Cluster quorum is established
• The master node pmx-01 of the HA group is active and the timestamp of the last heartbeat has been checked
• All the three member nodes of the HA group are active and the timestamp of the last heartbeat has been checked
• The VM service for 100 has been started on the first node, pmx-01
