VS control

My F5-1500 is now 9.4.8.

 

I want to 'dsiable' a virtual server when an unrelated pool has no active nodes. I used the 'discard' command to prevent VS access since I could not find any 'disable' command. My problem is that when the pool once again has active nodes I can not get the VS to accept messages again. That is, the 'discard' works but I can't turn it off except by manually removing the irule. Is there a way to restart the VS when the pool has active nodes again?

The unrelated pool is 'ISD-Switch-pool'.

 

On EFT-VS resources, I have assigned EFT-pool and this iRule:

 

 

when HTTP_REQUEST {

 

if {([active_members ISD-Switch-pool] < 1)}

 

discard

 

elseif {([active_members ISD-Switch-pool] > 1)}

 

{ node "10.89.80.34" }

 

elseif {([active_members ISD-Switch-pool] equals 1)}

 

{ pool EFT-pool } }
