the historical data into the data table. For this reason, the table
displays a maximum of 1000 rows of data, beginning with the most
recent, even if more data is available. (The chart displays
information for the entire range.) To view all of the data, you need

Reporting Data Files
• 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)
from the tape drive.
• To see the exact values of each item in the displayed chart, move
your mouse so that it "hovers" over the item you wish to see. An
information bubble displays with the values listed in it. If you click
on a bar, point, or slice, the information bubble locks in place and
the hovering feature turns off until you reload the chart. The
hovering feature does not work when the value equals zero.
• Values of zero do not appear in Pie charts.
This report identifies how tape drive resources are utilized in your
library. You can use this report to help you determine the proper work
load distribution between the tape drives in your library.
The following information is collected for each tape drive installed in the
library:
• Drive location (module, row)
• Drive serial number
• Partition
• Megabytes read
• Megabytes written
• Time and date of mount (UTC)
• Time and date of dismount (UTC)
