If the F5OS configured DNS server is not reachable then the cluster summary status displays 'Check DNS server configuration'. This warning is not specific enough to quickly identify the problem due to it appearing as if the cluster DNS is problematic, rather than the F5OS configuration.
The DNS warning on the cluster summary status slows the process of identifying the cause of the message.
The DNS server that was configured on F5OS is not reachable.
Configure reachable DNS servers on F5OS. For example: syscon-2-active# config Entering configuration mode terminal syscon-2-active(config)# system dns servers server 10.1.1.1 syscon-2-active(config)# show cluster The output of "show cluster" may take a short time to update, assuming the configured DNS IP(s) is reachable.
Delete the "Check DNS server configuration" cluster summary and change the event log as well.
