DR Primary Sites Scenario 4 – Loss of the Primary Site
If the primary site containing read/write database replicas were to go offline, the following actions should be observed or taken:
- Failover of the primary instance to a synchronous-commit instance in the secondary datacenter - configured per Microsoft best practices; this may be a manual or automatic failover.
- Manual Role configuration of the U-Series Appliances in the secondary datacenter to provide at least one Admin Role (for Smart Rule processing and system configuration).
- Depending on SSRS configuration (location of reporting database), the Reporting Role should be enabled on an alternate U-Series Appliance, or the reporting database restored to a backup U-Series Appliance
- Users should automatically be redirected to an alternate U-Series Appliance portal via load balancers.
