With our window approved, we finally completed our jump to 11.4.0 HF4.

 

When putting the two servers back into sync with each other, we ran iqdump from each GTM to its partner. We found a mismatch so we had to do big3d_install from the higher level server to the lower.

 

Please note: in 11.4.0 ( maybe in other versions ) your GTMs will report themselves as being 'Active' and 'standalone'. This is for the LTM status ( even with LTM receiving no provisioned resources ). Your GTM config and HA is set in the GUI through "System->Configuration->Global Traffic->General".

 

A test of creating an empty WideIP and watching it sync to the other node(s) will verify that GTM sync is working.

 

Other than the small wrinkle with the big3d version not getting upgraded somehow on one of the systems, and a few extra reboots when our systems upgraded the BIOS, HSB and AOM, the process was as advertised.
