Issue

While attempting either a system node reboot or system node halt in a two node cluster the following warnings are seen:

cluster1::> system node reboot -node cluster1-01

Warning: Rebooting or halting node "cluster1-01" in an HA-enabled cluster might result in client disruption or data access failure. To ensure continuity of service, use the "storage failover takeover" command.
         Are you sure you want to reboot node "cluster1-01"? {y|n}: 

cluster1::> system node reboot -node cluster1-01 -inhibit-takeover true

Warning: Rebooting or halting node "cluster1-01" in an HA-enabled cluster with takeover inhibited might result in a data serving failure and client disruption. To ensure continuity of service, do the following before rebooting or halting the node. Disable cluster HA using the command: "cluster ha modify -configured false".
         To transfer epsilon to the partner node, use the following commands (privilege:advanced):
                cluster modify -epsilon false -node <local-node>
                cluster modify -epsilon true -node <partner-node>
Do you want to continue? {y|n}: 

cluster1::> system node halt -node cluster1-01

Warning: Rebooting or halting node "cluster1-01" in an HA-enabled cluster might result in client disruption or data access failure. To ensure continuity of service, use the "storage failover takeover" command.
