A method and system for performing a failover process on a production
server. A source server and disaster recovery server are assigned
indicators when operating in failover mode. A version match is performed
to validate that the Exchange server applications and the storage area
network vendor resources are compatible for the source and disaster
recovery servers. Thereafter, multiple mailbox stores are dismounted on
the source mailbox server. In turn, multiple databases and multiple
transaction log drives are dismounted. After this step, drives are
mounted in the disaster recovery location that are mirrors of the source
server database and transaction log drives. After mounting, an Exchange
System Attendant resource is created or Exchange and user attributes are
updated in Active Directory. Finally, Exchange services are started and
mailbox stores are mounted on the disaster recovery server.
