of tape drives, tape cartridges, and TapeAlert flags. This information
can help you determine if a problem is due to a specific tape drive
or tape cartridge.
Media Security
Media Security enables you to be notified if media is removed from
the library without the administrators' knowledge or without
direction from the backup application.
Details about using Advanced Reporting include:
v The data for these reports is collected in log files that are located under
the Service Library menu tree on the IBM UI. When the log files reach
their maximum size, the oldest information is deleted as new information
is added. This can affect how much historical data you can access.
v The on-screen report contains a chart and a data table. When the log files
are large, it can take a long time to load all the historical data into the
data table. Therefore, the table only contains data for the previous seven
days, even if you select a range longer than seven days. The graph,
however, displays information for the entire range. To view all of the data,
you must save or email the data file. For more information on saving and
emailing the data file, see "Saving and Emailing Advanced Reporting
Reports and Logs" on page 2-18.
v The reports are built according to data in the log files, not data in the
current library configuration. Therefore, 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.
v Information about a tape drive, cartridge, or operation is not recorded in
the Drive Utilization log file until after a tape cartridge has been mounted
(loaded) and unmounted (unloaded) from the tape drive.
Drive Utilization Reporting:
The Drive Utilization function records drive, read, and write history which can be
used to identify drives or groups of drives that are nearing 100% utilization. It also
identifies drive resources that are not being fully utilized. These reports provide
the customer with information necessary to determine if, and when, additional
drives are necessary.
Data collected and saved for these reports include the following:
v Drive location (module, row)
v Drive serial number
v Logical library
v Megabytes read
v Megabytes written
v Time and date of mount (in GMT)
v Time and date of dismount (in GMT)
v Media motion time (in seconds)
v Media barcode
You can only access this report from the web client. The path to open the report is
Monitor System → Advanced Reporting → Drive Utilization.
