Attention: Maintenance functions cannot be performed concurrently with read or
write operations. While in maintenance mode, the tape drive does not accept host
interface commands from the server.
Table 3-3 describes each diagnostic and maintenance function that the drive can
perform, gives the function code which appears on the Single-character Display
(SCD), and directs you to the instructions for performing the function. It is
recommended that you use a customer-supplied scratch (blank) data cartridge for
diagnostic testing.
Note: During normal operation the fan only runs when cooling is required. The
fan will be turned on/off during the POST and Run Drive Diagnostics to
demonstrate the fan is operational.

1
Run Drive Diagnostics: Runs tests to determine whether
the drive can properly load and unload cartridges, and
read and write data.

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 3-10
3
Create FMR Tape: Copies its field microcode
replacement (FMR) data to a customer-supplied scratch
(blank) data cartridge.

page 3-11
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 3-11
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.

page 3-12
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 3-13
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 3-14
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.

on page 3-15
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).
