• The reports are built according to data in the log files, not your
current library configuration. For this reason, your library may
contain tape drives or cartridges that do not show up in the report.
Similarly, the report may contain tape drives and cartridges that no
longer reside in the library.
• Information about a tape drive, cartridge, or operation is not
recorded in the Drive Resource Utilization log file until after a tape
cartridge has been mounted (loaded) and unmounted (unloaded)
from the tape drive.
