Recovering from a failed LUN transition
If the transition of volumes with LUNs fails, you can use the lun transition 7-mode show command to check which LUNs were not transitioned to ONTAP, and then determine a corrective action.
- 
Change to advanced privilege level:
set -privilege advanced - 
Check which LUNs failed:
lun transition 7-mode show - 
Review the EMS logs and determine the corrective action that you must take.
 - 
Perform the required steps shown in the EMS message to correct the failure.
 - 
If any supported LUNs failed the transition, then to complete the transition:
lun transition start - 
View the transition status of the volumes:
lun transition showThe transition status can be one of following values:
- 
active: The volume is in an active SnapMirror transition relationship and not yet transitioned. - 
complete: All supported LUNs are transitioned for this volume. - 
failed: LUN transition failed for the volume. - 
none: The volume did not contain LUNs to transition from 7-Mode systems.
