During movement of data (migration, reclamation, move data) from a sequential volume, one or more files were encountered that were locked by a restore operation.
The files are not moved, but are skipped.
Use the QUERY RESTORE FORMAT=DETAILED command to determine if the restore operation is active or is in restartable state. A restartable restore operation will keep the files locked from movement until the RESTOREINTERVAL is reached. QUERY OPTION will display this interval. You may wish to lower the RESTOREINTERVAL to cause a restartable restore operation to be removed and free up the locked files. The RESTOREINTERVAL is a server option. If you received this message due to a MOVE DATA operation, reissue the MOVE DATA command after the restore operation has completed in order to move any remaining files.
