TAPEUTILIZATION PERCENT=(pct | NOLIMIT), (UNIT=unit CAPACITYMODE=(EXTENDED | COMPATIBILITY | **NONE**)) | LIBRARYMIGRATION | LIBRARYBACKUP

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.

System action

DFSMShsm processing continues.

Programmer response

Verify that these are the desired settings. If not, reissue the SETSYS TAPEUTILIZATION command with the proper parameters.
