Compare Statistics utility
Table 33 Compare Statistics utility details
Compare Statistics utility Details/Device Specific utility
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 Description
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.
NOTE: For instructions on how to perform this utility, see “Running tests and
device-specific utilities” (page 29) or “Running the tests (CSI)” (page 50) .
