High Availability Guide : Watchdog sample : Failure situations and Watchdog actions : Communication link between the Watchdog and Primary is down
  
Communication link between the Watchdog and Primary is down
Scenario
The connection between the Watchdog and the Primary server is broken.
Remedy
The Primary and Secondary servers can continue operations even when the Watchdog link to the Primary server is down. When the Watchdog link to the Primary is fixed, be sure to check the states of the Primary and Secondary servers.
1 Fix Watchdog’s network connection to Server1.
Symptoms
The Watchdog poll fails at the Primary server. However, the secondary server state is reported to be SECONDARY ACTIVE. This means that the primary server is very probably okay and that the Watchdog has merely lost contact with the Primary.
Further scenarios
If the states of the servers have changed and one server is no longer in service, refer to the applicable scenario in this section for instructions.
