Performing an Exception Switchover
Function
This API is used to perform an primary/standby switchover when a DR exception occurs.
To perform a switchover when the DR cluster is abnormal or the production cluster is faulty, you can click Exception Switchover on the console.
DR exception switchover is supported only by clusters of version 8.1.2 or later.
Before a switchover, check the latest synchronization time in the DR cluster. The DR cluster will serve as a production cluster after a switchover, but the data that failed to be synchronized from the original production cluster to the DR cluster will not exist in the DR cluster.
This function is available only for DWS 2.0 clusters.
