5.2.3.7 Virtual Tape Volume Migrate Request File

At the DETAIL timespan, this file describes the event where a
virtual tape volume is requested to be migrated to a
multivolume cartridge.  It is derived from the VTSS user SMF
record, subtype 18.  This record is produced for every
virtual tape volume that is migrated to real tape.

The SVTVGR file contains interesting metrics pertaining to
the migration reason and the elapsed time since the virtual
volume was last mounted on a virtual tape drive (ie; disk
buffer residency time).  In addition the file can be used to
determine migration durations, frequency of migrations, and
migrated data volume.

The following sections describe the file's organization, list
the data elements maintained, and provide usage hints.
