Symptoms

In a VTL High Availability (HA) configuration, both nodes can failover to each
other, causing a "mutual failover" condition.

This is the expected reaction for VTL in an HA config under certain circumstances for
precautionary measures. For example, in a power outage situation this is expected.
Both servers are red in VTL Console indicating it has failed over. Each node can be
servicing the others resources or neither taking control of the other.
Or only one server may be servicing the other's services and the other node may not be due
to the failover not completing completely (this can happen when the one node fails over
completely first, and the second then can't complete the failover).

Changes

Network changes can cause this condition.
