A move data process for an offsite volume 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 copy of the aggregate to which the file belongs on an accessible volume.
The file will skipped and will not be moved from the offsite volume.
The indicated storage pool is a primary pool that should contain a primary 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 the offsite volume that was involved in the move data process. If you bring this volume back onsite, you can recreate the file in the primary pool by using the RESTORE STGPOOL command. After the restore, you can reissue the MOVE DATA command.
