NimbostratusLTM 1600 - 10.2 - Drop all connections to member
Hey guys,
Is there a way to sever all connections to a specific pool member within the LTM? We currently force offline nodes when we want to take them out, but it takes several minutes for the connections to drain off and even then, existing connections continue to persist. Due to our workflow, this behavior puts a damper on deploying for our clients and causes people to reconnect to servers that are undergoing maintenance.
Our pool setups currently have:
1) Src-IP persistence
2) Reselect on service down
3) Disable by force offline
Any help would be greatly appreciated.
Thanks

i understand forced offline would leave only active connection.
sol7566: Disabling nodes or pool members for maintenance (9.x - 10.x)

to drop active connection, is manual deleting connection through tmsh acceptable? - The easiest way (in my mind...) is to force a monitor failure on the node. As soon as the node is marked offline/down it will kill all connections and not send anymore to it.
One way to do this is set the node to a node specific monitor and put an http monitor on it if it's only ftp or the reverse of that. Then it causes a failure, kills everything and you're offline.
The other option (for http) is to put a http disable string into your http monitor. Then, when you want it offline for maint. simply send the disable string to the LTM from the server and it will mark it down.
