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.
