Process summary
The steps you take for failover and failback vary depending on the type of failover or failback you perform. Failover and failback types include:
Planned failover: This is performed to switch the job roles of source and destination clusters.
Failback after a planned failover: This is performed after a planned failover to switch the roles of the clusters back to the original state.
Unplanned failover: This is performed when the primary cluster is down and disaster recovery has to be performed.
Failback after an uplanned failover: : This is performed after an unplanned failover or disaster recovery.
Each process is summarized in the following sections. Typically, you would use the planned failover and planned failback processes in most situations.
