A reclamation process of offsite volumes cannot locate a copy of the specified file in any storage pool accessible by the server. If this file is part of an aggregate, the process could not locate a copy of the aggregate to which the file belongs on an accessible volume.
The file is skipped and will not be moved from the offsite volume.
The indicated storage pool is a primary pool that should contain a copy of the file. Perhaps the volume on which that file resides is on a destroyed volume. The only usable copy of the file may now only reside on an offsite volume that was involved in the reclamation process, but was not totally reclaimed. If you bring this volume back onsite, you can recreate the file in the primary pool by using the RESTORE STGPOOL command.
