Disable pool member using iRule

Hey Everyone,

I'm trying to disable a pool member using an HTTP request, so that my team and I don't need to be awake and online for server maintenance. Below are both of the rules I've tried to use to accomplish this. The second one works, but comes up on the next health check and the first one doesn't work at all.

These requests trigger off of an HTTP request like this http://10.10.10.100/down/10.15.15.150

I've included the logs that come up after using each iRule

when HTTP_REQUEST {
   if {[scan [HTTP::uri] "/down/%s" server] == 1} {
      LB::down node $server
      log local0. "URI: [HTTP::uri] MATCHED. server=$server"
  }
}

when HTTP_REQUEST {
   if {[scan [HTTP::uri] "/down/%s" server] == 1} {
      LB::down pool SOMEPOOL member $server 80
      log local0. "URI: [HTTP::uri] MATCHED. server=$server"
  }
}

Could an iRule be used to trigger a tmsh command or something along those lines to accomplish this?

Thanks
