HWN023038E The request failed because the copy specified does not exist.
Explanation
The request failed due to the copy specified no longer existing. It is possible that the volume has already been migrated to a new target pool.
Action
If the analysis that generated the recommendation was performed sometime in the past, it is possible that an entity that was part of the recommendation is no longer detected by TPC. It would therefore be recommended to resubmit the analysis job to generate a new set of recommendations that would not contain entities that no longer exist.
