GTM DNS responses not reflecting pool availability
I've got a pair of 3410 units, each with GTM enabled. I've got the LTM configuration on each working, but I can't get GTM to work the way I think it should.
LTM on each unit is configured with a pool of servers. GTM is then pointed at both LTMs, and I have wide IP everything is under.
When I send DNS queries for the name of the WIP, it happily returns back both of the LTM virtual servers. If I update the GTM pool, removing and adding virtual servers discovered from the LTMs updates the DNS responses that GTM sends out.
The problem I'm running into, though, is that when the virtual servers on an LTM is disabled (either by manually taking down the real servers, or just disabling it in the LTM config), this is not reflected in the GTM DNS answers. Looking at the GTM status does accurately reflect the fact that one of the LTM virtual servers is disabled, but it keeps returning both LTM IP addresses.
Am I correct in assuming that the DNS answers returned by GTM should reflect what resources are actually available? Or is there something else I've completely missed here?
