Function Code 0:
Maintenance Mode
Function Code 0 makes the drive available for running drive diagnostics
or maintenance functions.
1 Place the drive in Maintenance Mode. For instructions, see Entering
Maintenance Mode on page 45.
2 To exit Maintenance Mode, see Exiting Maintenance Mode on
page 45.
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 56. 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. Gen2 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., Gen3 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 45.
