      You can ask him to explain this to you. Basically, you don't want to have any current connections to those pool members, because they will be disrupted when you take the pool members out. You don't want any persistence entries because if there are persistence entries pointing to a non-existent pool member, the system may attempt to send connections to the non-existing pool member (you have to test this to confirm). You should be able to mark the pool members as disabled, and they will continue serving active and persisting connections, and periodically check the connection table until when there are no active sessions and no active connections to the pool members, then you can remove them. `tmsh show sys connection ss-server-addr ` Above command shows you all the connections current to a particular server. `tmsh show ltm persistence persist-records node-addr ` This command should show you the persistence records for a particular server IP.
