Just discussing .... I am not finding much information on the internet regarding CAS 2013 NLB High availability in DR
scenario so planned to discuss and get some ideas/guidance
Site-A
Domain Controllers x2
3 CAS servers with hardware LB
3 mbx servers in DAG1
FSWitness Server
SAN Wildcard Certificate
Exernal URL: webmail.domain.com/owa
Internal URL: autodiscover.domain.com
Site-B (DR) with Stretched DAG
Domain Controllers x3
3 CAS Servers with wNLB
2 mbx server in the same DAG1 (Stretched)
Alt FSWitness server
External URL: webmail.domain.com/owa
Internal URL: autodiscoverDR.domain.com
Question:
When Site-A goes down .....
I understand the other steps which need to be taken but my question is
in DR Site, do I point my internal URLs to the mbx servers using the same
commands to set the virtual directories as usual and point them to the new mbx servers dbs?
And when the primary site comes back up follow the same steps to revert back? I am bit unclear on this part?
Thank you
