Hi Joe,
Thanks very much for your response, I've now got a much more user friendly view of the current pool member states using the toggle state method in the tech tip you mention above!
I'm currently re-engineering some scripts to work with F5s rather than CSMs which we used before so its just getting used to the slight difference between setting a weight then taking the service out and back in to setting it to disable and then forced offline.
Could you just cofirm that my thinking is correct here with the 4 possibilities when taking a service out and back in gracefully...
Monitor state ENABLED + Session state ENABLED = Accepting all sessions old and new
Monitor state ENABLED + Session state DISABLED = No longer accepting new connections
Monitor state DISABLED + Session state DISABLED = No connections at all
Monitor state DISABLED + Session state ENABLED = People can hit this URL but it's offline so bad news (is that correct?)
If that last point is correct then I need to be sure to ENABLE the monitor state before the session state when bringing the services back online.
The reason I don't wait for all the connections to drop to 0 is because we don't have a very long window to upgrade our app servers behind the URLS so I give everyone 25 minutes to log off and back on through a different URL still accepting sessions before I take it down anyway.
Again, thanks for the help.
Alex
