How Do I Resolve Error "Target server has fewer disks than source server. Select another target server" When I Configure the Target Server?

Symptom

When you clicked Next: Confirm after you select an existing ECS as the target server, the message "Target server has fewer disks than source server. Select another target server" was displayed.

Possible Causes

When configuring the target server, SMS checks whether the target server has the same number of disks as the source server. The number of disks on the target server is less than that on the source server because some disks on the target server may have been deleted or detached.

Solution

1. In the navigation pane of the SMS console, choose Servers.
2. Locate the source server and choose More > Delete Target Configuration.
3. Attach disks to the target server to ensure that the target server has at least as many disks as the source server.
4. Go back to SMS console, locate the source server in the server list, and click Configure in the Target column. Configure a target server and perform the migration again.
