How Do I Resolve Error "Some disks on the target server are smaller than those on the 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, message "Some disks on the target server are smaller than those on the source server. Select another target server" was displayed.
Possible Causes
When you configure a target server, ensure that the following requirements are met:
- The target server must have at least as many disks as the source server.
- Each disk on the target server must be at least as large as the paired disk on the source server.
If the requirements are not met, the preceding message will be displayed.
Solution
- Locate any target server disks that do not meet the second requirement, and expand these disks on the ECS console to be at least as large as their paired source server disks.
You can expand the target server disks based on the recommended disk sizes on the Configure Target page of the SMS console.
If the second requirement can be met by adjusting the disk mounting sequence, perform the following steps:- Go to the ECS console and stop the target server.
- Detach all of the disks from the target server.
- Attach these disks back to the target server based on the recommended disk sequence displayed on the Configure Target page of the SMS console.
- Switch to the SMS console and select the target server you just configured.
