labels, and keep correct inventory. The test will fail immediately
upon the first robotics error.
• No tapes in the selected drives. If there are tapes in any of the
selected drives, the test will move the tapes back to their source
slots at the beginning of the test. A working library should know
the source slots for each tape, as long as the library has not been
rebooted or power-cycled since the tape was loaded into the drive.
If the source slot information is not available in the library, the test
will exit with an error message requesting that the user use the front
panel to replace the tapes in their storage slots.
• Bar code labels are correct. The test uses the bar code labels to
determine whether a tape may be used in a specific drive. The sixth
and seventh characters in the bar code label designate the type of
tape. In addition, cleaning tape bar code labels start with “CLN”,
which is used to exclude any cleaning tapes from the test. The test
chooses which tapes to include based on the bar code labels of
the tapes in the library, along with the option settings for Drive
type, Starting slot, and Number of test tapes.
The requirement for correct bar code labels may be overridden by
setting the [Ignore barcode labels] test option to TRUE.
NOTE: The test will not run with the Ignore barcode labels
test option set to TRUE if the library has mixed drive types because
when the library contains mixed drive types it is more likely that
some of the tapes in the library are not compatible with the chosen
drive type.
• Library is configured to show at least seven bar code characters.
The library must show at least seven bar code characters for the
test to check the bar code labels. The number of bar code characters
shown is a configuration setting that differs between libraries. If the
library is set to show fewer characters, the test will behave as though
none of the tapes in the library are compatible with the chosen tape
drive.
The Library Read Write test keeps a log file containing a list of all tapes
in the library that were identified during previous test runs. This
information is used within the test if the Skip previously
inventoried tapes test option is set. The log files are named
LTTRootDirectory\logs\ProductID_ProductSN_librw.csv.
The list has one entry for each tape, and each entry includes the bar
code, slot, and media ID for SDLT tapes or cartridge SN for LTO tapes.
The bar code and slot information will always be present; the media ID
or cartridge SN will only be present if the tape was loaded during any
run of the Library Read Write test. The log file may be viewed in Excel.
When the Library Read Write test runs, the media ID or cartridge SN
from the log file is combined with any new media information from that
run. The log file is then updated to reflect the new media ID or cartridge
SN information, as well as the current library configuration of tape
locations. If the Library Read Write test is run after a tape is removed
from the library, the information about that tape is discarded from the
log file.
