Why Can't I Attach the Original System Disk Back to a Target Server?

Symptom

If a migration fails, the system disk of the target server is a temporary disk with the disk name starting with sms. As a result, the original system disk of the target server cannot be attached back.

Possible Causes

The temporary system disk was not detached. You need to manually detach the temporary disk.

Procedure

The following uses Linux as an example to describe how to handle this problem.

1. Connect the source server to SMS by switching to the SMS-Agent directory on the source server, running ./agent-cli, entering connect, and pressing Enter.

   

2. Run clear in the CLI.

   After about a minute, the temporary disk on the target server will be detached and deleted, and the original system disk will be re-attached.
