Run the Self Test
Self Test tests sensor input and robotic motion to make sure the system is operational.

Drive Maintenance Test
Drive Maintenance allows you to perform several different drive diagnostic tests.
To better understand these tests, you need to understand the format of the tape. The tape is divided into 4 data sections. Each data section contains 96
tracks (96*4=384 tracks, the number of tracks on a Generation 1 cartridge). On each edge of the tape (2 servo bands), and between the databands (3 servo
bands), there are pre-formatted servo bands (5 in total). A wrap is defined as a trip from logical BOT to logical EOT (a round trip would be 2 wraps).
The drive maintenance options are described in more detail below.
to dismiss.
Selection Description/Result
Step 1 From the Tools menu, highlight
and press .
Runs self test.
Step 2 A status screen will display the
progress of the test. You can press at
any time to cancel the test.
The self test begins.
Step 3 When the test is complete, a
completion message is displayed. Press
to dismiss.
If the Self Test fails, there is probably
something obstructing motion of the picker.
Open the door and pull out the magazines to
verify that all the tapes are pushed into their
slots. Look for anything that appears to be
blocking the path of the picker. Retry the Self
test. If it still fails, contact Technical Support.
NOTE: The Drive Maintenance tests are only supported for libraries with LTO drives. WORM media cannot be used when running diagnostics.
NOTE: Run time records the test time in minutes and seconds (m:ss).
Test Description
Power on self test
(POST) Runs self diagnostics. This test takes approximately 1 minute.
Fast Read/Write The drive reads and writes 2 wraps worth of data (a trip down and
back) in each of the 4 data sections. 10 data patterns are used in this
test. No more than 1.5 % of the tape is used. This test takes
approximately 3 minutes.
Normal
Read/Write The drive reads and writes 96 wraps worth of data (all the tracks) in
each of the 4 data sections. No more than 1.5 % of the tape is used. 10
data patterns are used in this test. This test takes approximately 22
minutes.
Media Read/Write Since media damage usually comes from the edges of tape to the
center of tape, the media test performs a read/write test by writing 2
wraps on each of the two outside data bands, closest to the edge of
tape, on both edges of the tape, for the entire length of tape. This test
takes approximately 20 minutes.
Head Read/Write In this test, the drive performs a resistance check on the recording
head, then it does a read/write test where it writes 2 wraps in each of
the two center data bands of tape to verify the head is performing well.
This test takes approximately 20 minutes.
Wrap This test is used to ensure that the drive is communicating correctly
with the host and the library.
Create FUP The drive loads firmware onto a data cartridge to create a firmware
upgrade (FUP) tape.
Clear FUP The drive erases the firmware from the firmware upgrade (FUP)
