Explanation
Here are the values that are specified by the
SETSYS TAPEUTILIZATION command:
- pct
- This is the amount of the tape volume that will be written until DFSMShsm forces
the end of volume.
- NOLIMIT
- DFSMShsm will
write to the tapes until the actual end of volume is reached.
- UNIT
- This is the unit type that the settings pertain to.
- CAPACITYMODE
- This pertains exclusively to user-defined esoterics that contain
only IBM® 3590 tape drives that
emulate 3490 and are capable of CAPACITYMODE switching.
- EXTENDED
- The tapes can be filled more fully, but with a loss of compatibility
with emulated 3490 drives that are not capable of CAPACITYMODE switching.
- COMPATIBILITY
- The tapes will be filled only as far as emulated 3490 drives can
fill them (without CAPACITYMODE switching support).
- **NONE**
- The drives in the esoteric do not support CAPACITYMODE switching.
- LIBRARYMIGRATION
- This value represents the percent utilized for migration tapes
that are stored in a tape library.
- LIBRARYBACKUP
- This value represents the percent utilized for backup tapes that
are stored in a tape library.
