Table 11 Library Read Write test details (continued)

Library Read Write test

Details/Library specific test

sequence will be repeated for each tape/drive combination.

Ignore barcode labels

(default: FALSE) — Specifies whether the test should

use barcode labels to determine which tapes are compatible with a tape drive.

Skip previously inventoried tapes

(default FALSE) — Specifies whether

previously inventoried tapes will be skipped when the test selects the tapes to use
for the test run. The information about previously inventoried tapes is kept in the
log file.

Depending on the library model and test options selected, this test may overwrite data.

Other notes

This test can be stopped before it completes. To abort the test from the GUI, click Abort
Test. To abort the test from the CSI, use the Ctrl-A key combination.

In L&TT 4.5 and later, the test keeps a log file that lists of all tapes in the library that
have bar code labels.

The test will not run with a tape that has been partitioned.

The Library Read Write test has several requirements, some of which can be overridden
with test options:

Library robotics are working. The test assumes that the library robotics are working
well enough to move tapes, read barcode Diagnostic tests 123 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.

Starting with L&TT 4.5, 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
