Scenario: A Citrix Administrator manages an environment that has a NetScaler high availability (HA) pair running on two MPX appliances. The administrator notices that the state of the Secondary NetScaler is
'Unknown' and moves the Secondary NetScaler to a new switch as a result. Also, the administrator captured a packet trace on both NetScalers. Both sent traffic on secure port 3009 and were routing back and forth to each other.
What is causing the Secondary state to be 'Unknown'?
