Mark a VS down when 2 pool members are down

As an alternative, you could set up an iRule to redirect requests to a "Sorry page" if the number of active members in the pool fall below a set number. The one below is similar to what we use when performing maintenance on a pool's servers.

when HTTP_REQUEST {

 if { [active_members [LB::server pool]] == 0 } {

HTTP::redirect "http://www.mycompany.com/sorrypage.htm"

}

}

If not, you may still find a use for it...

Good luck!
