Pool Member Inactive - Red diamond

So this is likely to be a monitor issue, but cant be sure whether this is due to the upgrade or not. Do you have a monitor on the node, like ICMP? If this is up, can you telnet to port 7071 from the f5 cli to the pool member? If both successful then is it a case of selecting the pool member and just enabling it?

​

Difficult to say what the issues are but try above and it may lead you to a root cause.

​

Hope this helps,
