SRM provides users the ability to test their recovery plans in an isolated environment. Testing recovery plans allows customers to test their disaster recovery ability without impacting the production applications and replication. The testing of the recovery plans is achieved by leveraging local replication technology provided by the storage arrays, in this case the Test Failover functionality that is inherent in PowerFlex replication.
The PowerFlex takes an on-demand snapshot during a Test Failover and point the existing mapped volume at the target to that snapshot, enabling read/write access. Any changes made to those snapshot volumes are discarded when the test is complete.
This chapter describes the following topics related to test failover:
