2.Handling methods
a.Method 1: If steps following storage space resetting succeed, ignore the storage space resetting failure. If steps following storage space resetting fail, clear recovery plans again.
b.Method 2: Download the operating system patch of the desired version from the support website of Windows. Install the patch on the host and restart the host. Then clear recovery plans again.

Introduction to recovery plan tests executed by the OceanStor ReplicationDirector
You can test a recovery plan to verify the availability of the data replicated to the disaster recovery site. During a test, the disaster recovery site generates test data using snapshots, which does not have any impact on the production site. After the test is complete, the test environment must be cleaned up. Before a failover or planned migration, at least one recovery plan test must be executed successfully. The test can be performed only in the disaster recovery management system at the disaster recovery site.
