Resolution –

Start-DatabaseAvailabilityGroup -MailboxServer ESES01

Note : In my case – Server in my primary site,DAC(Datacenter Activation Coordination mode) is ON , Databases are already in Exch01. Started DAG saying ESES01 is live and functional and to check the started and stopped DAG members to come out the confusion.

Now Mounted all databases Successfully.
