I experienced similar issue of GTM pools being marked down when upgrading from 10.2.4 to 11.4.1 HF4 (HF5 was not out). I punted to previous version to investigate. All server/member/node objects in the GTM were added manually. I suspected something changed with the custom health monitors, but it looks like you had the same problem with default monitors. I do not currently have a GTM/LTM iquery mesh. I plan to configure iquery with our LTMs when I get the GTMs up to 11.x. All pools are green in 10.2.4, so firewall rules should be in place.
