agree with @brad parker. iCall is probably the better tool for bringing a virtual server up/down based on pool-statuses. iRules are traffic-driven and event-based, so the vs up/down action can only be performed when the iRule processes traffic. If the virtual server is disabled and GTM never resolves the hostname to the virtual address (because the virtual servers are down), then the iRule will never receive traffic to bring the virtual server back up.
