Symptoms
AppSync supports re-linking for SnapVX Clones on VMAX 3.
However this is not supported when an existing Clone Copy is mounted and the rotation is set to 1.
Cause
AppSync cannot re-link to a mounted target device.
Resolution
Set the rotation to 2 copies or more.
This should ensure another copy is available and assuming it is not mounted, it will be used for re-linking.
Alternatively, unmount the existing copy manually before running the service plan.
