My scenraio is I have 2 AD sites, 2 MBX server in the primary, 1 MBX in the secondary with DAC turned on.
All 3 servers hold active DB copy.
My question is to what steps I need to take when the WAN link between the sites is down.
I know that the DB's in the secondary site will auto dismount, and auto-mount in the primary site.
But how do mount them in the secondary site without causing split-brain syndrom?
And also, whats steps should I perform once the WAN link is back up and running again?
