Scenario: A Citrix Administrator is performing a disaster recovery test and decided to fail over the Citrix ADC high availability (HA) pair appliances. The administrator noticed that the failover is NOT working as expected in item text, and the Secondary Citrix ADC is NOT taking over as Primary. The administrator suspects that networking issues may be causing the failure.
What could be the cause of this issue with the Citrix ADCs?
High Availability (HA) monitoring needs to be enabled on operational network interfaces. If HA monitoring is enabled on an interface of the Secondary Node that shows as ENABLED but is DOWN, it can lead to the Secondary Node not taking over as Primary during a failover. This can result in the failover not working as expected because the Secondary Node is not in a state to take over properly.
B as per https://support.citrix.com/article/CTX204685
D - https://support.citrix.com/article/CTX204685 Symptoms or Error HA state for secondary shows as NOT up Solution Check the following : 1. Both nodes should be same hardware and software. 2. RPC node on both nodes should be same. (till 11.0 xx) 3. Connectivity on port 3009 3011. 4. Any down interfaces on NetScaler should not have HA monitoring enabled.
D says that the interface is DISABLED not DOWN. According to the article, should be B.: Interface ENABLED, DOWN.
D: because Any down interfaces on NetScaler should not have HA monitoring enabled.
i think is b too https://docs.citrix.com/en-us/citrix-adc/13/system/high-availability-introduction.html
