instructions for performing the function. It is recommended that you use a customer-supplied scratch
(blank) data cartridge for diagnostic testing. The diagnostic and maintenance functions are not supported
on the WORM and partitioned data tape cartridges.

Function
Code
Diagnostic or Maintenance Function Instructions Location
0
Exit Maintenance Mode: Causes the drive to become
available for reading and writing data.
“Function code 0: Maintenance mode” on
page 23
1
Run Drive Diagnostics: Runs tests to determine whether
the drive can properly load and unload cartridges, and
read and write data.
“Function code 1: Run drive diagnostics”
on page 24
8
Update Tape Drive Firmware from FMR Tape:
Loads
updated firmware from a field microcode replacement
(FMR) tape.
“Function code 2: Update drive firmware
from FMR tape” on page 24
3
Create FMR Tape: Copies its field microcode
replacement (FMR) data to a customer-supplied scratch
(blank) data cartridge.
“Function code 3: Create FMR tape” on
page 25
8
Force a Drive Dump: Performs a dump of data (also
known as saving a microcode trace).
“Function code 4: Force a drive dump”
on page 25
5
Copy Drive Dump: Copies data from a drive dump
(captured by using Function Code 4) to the beginning of
a customer-supplied scratch (blank) data cartridge,
copies a drive dump to flash memory, or erases a dump
from flash memory.
“Function code 5: Copy drive dump” on
page 26
6
Run Host Interface Wrap Test: Performs a check of the
circuitry from and to the connector.
“Function code 6: Run host interface
wrap test” on page 27
7
Run RS-422 Wrap Test: This test causes the drive to
perform a check of the circuitry and connector for the
RS-422 interface.
“Function code 7: Run RS-422 wrap test”
on page 28
8
Unmake FMR Tape: Erases the FMR data on a
customer-supplied scratch (blank) data cartridge and
rewrite the cartridge memory on the tape. This turns the
cartridge into a valid customer-supplied scratch data
cartridge.
“Function code 8: Unmake FMR tape” on
page 28
9
Display Error Code Log:
Displays the last 10 error
codes, one at a time (the codes are ordered; the most
recent is presented first and the oldest (tenth) is
presented last).
“Function code 9: Display error code log”
on page 29
A
Clear Error Code Log: Erases the contents of the error
code log.
“Function code A: Clear error code log”
on page 29
C
Insert Cartridge into Tape Drive: This function cannot
be selected by itself, but is a part of other maintenance
functions (such as Run Tape Drive Diagnostics and
Create FMR Tape) that require a tape cartridge to be
loaded.
“Function code C: Insert cartridge into
tape drive” on page 29
E
Test Cartridge & Media: Performs tests to ensure that a
suspect cartridge and its magnetic tape are acceptable.
“Function code E: Test cartridge &
media” on page 29
F
Write Performance Test: Performs tests to ensure that
the drive can read from and write to tape.
“Function code F: Write performance test”
on page 30
H
Test Head: Performs tests to ensure that the tape drive's
head and tape-carriage mechanics are working correctly.
“Function code H: Test head” on page 31
