Hi All,
Happy New year 2014 ....
we have running with exchange 2010 R1 with DAG enabled. we have below mentioned setup in our exchange server.
Main site.
Active directory server ( Primary DC, additional DC in our main site) installed in Hyper V host. installed exchange 2010 mail box role in another Hyper V host. installed the CAS& Hub role in another virtual host and installed the Exchange edge role in another physical server.
DR Site
Active director server( ADC) installed in Hyper V host. installed the Exchange 2010 mailbox,Hub,Cas server role in a physical server. installed the Edge Server in another physical server.
At present we have enabled the failover DAG for both our Mail box servers and its working perfectly when the primay mail box server down. we have run some commands to transfer all my exchange 2010 to point through our DR Site. so its take some of the minutes of down time happened in our mail flow. we are planning to avoid that downtime. we are find for the solutions like if the primary site down the DR will need to automatically up. it will be appreciate that any one provide your suggestion to achieve this without affecting the our current setup.
