Test results are displayed in the result log in the bottom right-hand corner of the Test/Utilities
screen and are available in the WebGUI install directory, C:\Program Files (x86)\
Hewlett-Packard\Library and Tape Tools WebGUI\log and it’s there
under LTTOperationLog.log. The log file contains all the previous text results and is a
text file that can be viewed in any text editor or sent by e-mail.
Device-specific utilities
L&TT provides three types of utilities:
• Device-specific utilities are accessed from the Utility screen and operated like the tests. This
section describes the device-specific utilities. See “Using the Test/Utility screen” (page 23) for
information on running the device-specific utilities.
• Device connection independent utilities are accessed from the Utilities > Run Utilities menu.
• SCSI utility scripts are run from the Utilities > Run Script menu.
CAUTION:
Some utilities are destructive to data on the media. When a utility is destructive to data, this is
indicated in the utility description. To prevent data loss, use media that is either new or that contains
unimportant data that can be erased. Do not attempt to perform a utility unless you are thoroughly
familiar with its usage, or have been instructed to do so by HP support personnel.

Compare Statistics utility
Description This utility reads current statistical values from the library (number of
moves and retries, for example) and compares the current values to
values saved previously in this library by this same utility. It can be useful
to run this utility before and after running another L&TT test that exercises
the library to see if there are changes in key statistics that would indicate
a problem. If the utility has never been executed before on the library,
there will be no results to make a comparison with, but the current
statistical values will be displayed and saved for comparisons when the
utility is run in the future. Depending on the library type, results can be
saved in the library for anywhere from one to four executions of the
utility.
When to run This utility is most useful when used in conjunction with tests by running
this utility before and after running a test that exercises the library.
Statistics, such as move retries, can then be compared to determine if
the library is running without error.
Average duration Since no library motion is necessary, this utility completes in just a few
seconds.
Other notes None
Available for This utility is available for MSL2024, MSL4048, MSL8048, MSL8048,
MSL8096, ESL E-Series, and the 1/8 G2 Tape Autoloader.
