What Can I Do If the Register VM Step Fails When Planned Migration Is Executed and a Message Is Displayed, Stating "LUN that is required by the VM has not been mapped to the host, has become invalid or has not been managed by a consistent group"

Symptom

When planned migration is executed for the first time, the Register VM step fails due to network problems. Then log in to FusionCompute and delete datastores that are created when executing planned migration. For details about the operations, see the FusionSphere Virtualization Suite Product Documentation. When planned migration is executed again, the Register VM step fails and a message is displayed stating LUN that is required by the VM has not been mapped to the host, has become invalid or has not been managed by a consistent group, as shown in Figure 1.

Possible Causes

When planned migration is executed again, the system detects that the Create DataStore step is not executed after planned migration is executed for the first time. However, datastores have been deleted from the FusionCompute page. As a result, the Register VM step fails.
