GTM Upgrade FAIL - DC Links & ICMP Monitors
We tried re-doing the bigip_add on all 3 sides and validating communication with iqdump, although I'm not sure how to make sure the iqdump messages were valid or not. Regardless, that didn't fix it.
The thing is VS discovery is not enabled due to NAT. So I am wondering if there was a bug introduced somewhere after 10.2.0HF2 that was not or is not corrected relating to GTM BIGIP monitors and NAT. Does anyone have any ideas?
UPDATE See my 2nd post in this thread. DC Link & gateway ICMP monitors are to blame but still no idea why. They are not sending traffic on 2 of 3 on 10.2.0 and when upgraded to 10.2.3, the 3rd stopped sending out pings as well...?!
