The drive exits Maintenance Mode automatically after it completes a
maintenance function or after 10 minutes if no action has occurred.
Function Code 1: Run
Drive Diagnostics
Approximate Run Time = 5 minutes per loop
Total Number of Loops = 1
Function Code 1 runs tests that determine whether the drive can
properly load and unload cartridges and read and write data.
Record the time it takes for the test to complete. Compare the recorded
time with the “Approximate Run Time” above. If the test runs
successfully but the execution time is significantly longer than the
“Approximate Run Time”, run Function Code F: Write Performance Test
on page 58. If the Write Performance Test fails, replace the media and
exit maintenance mode.
Caution: For this test, insert only a scratch (blank) data cartridge or a
cartridge that may be overwritten. During the test, the
drive overwrites the data on the cartridge.
Note:
If you inserted an invalid tape cartridge (e.g. Gen1 or WORM
media), error code
J
or
7
appears in the SCD. If you inserted a
write-protected cartridge, or the media has read-only
compatibility (e.g., Gen2 media), error code P appears in the
SCD. In either case, the tape drive unloads the cartridge and
exits Maintenance Mode after the cartridge is removed.
Steps to Execute Run Drive Diagnostics:
1 Place the drive in Maintenance Mode. For instructions, see Entering
Maintenance Mode on page 47.
2 Press the Unload button once per second until 1 appears in the
SCD. (If you cycle past the desired code, press the Unload button
once per second until the code reappears.)
3 Press and hold the Unload button for three or more seconds, then
release it to select function 1 . Wait for the SCD to change to a
flashing C.
