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.
