DR Failover Process

Here is the step-by-step summary failover plan at George Mason University:

• Shut down local databases (if possible).
• Disable data replication from the storage attached network (SAN) to the remote DR SAN.
• Initiate VMware Site Recovery via Site Recovery Manager (SRM).
• After the SRM failover is finished, initiate network routing changes.
• Present DR SAN storage to the remote DR servers (SRM automatically provides this function for VMware servers).
• Promote DR Active Director domain controller.
• Check status of DR LDAP, DR Kerberos and DR Active Directory.
• Run scripts to switch DNS for servers or update DNS manually if necessary. This includes the emergency static web page.
