Are you certain it is the GTM that is resolving the wideip to the DR vip? In the web interface check GTM virtual server statistics: Statistics >> Module Statistics: DNS: GSLB >> Statistics Type: Virtual Servers. The "Picks" column will show how many times GTM has resolved to each vip in the pool.

 

GTM should only pick the DR vip if the primary is unavailable according to the way global availability works. If GTM is picking the DR vip then I would suspect it either thinks the primary is down or you are facing a bug in GTM.

 

The monitor config you posted appears to be an LTM monitor. Does GTM also have monitors assigned to its pool members or virtual servers? These could be marking the GTM primary vip down causing GTM to resolve to the DR vip.
