Attention: Maintenance functions cannot be performed concurrently with read or
write operations. While in maintenance mode, the tape drive does not accept SCSI
commands from the server. The tape drive accepts LDI or RS-422 commands.
Table 8 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. 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.
Note:
During normal operation the fan runs only when cooling is required. The
fan will be turned on and off during the POST and Run Drive Diagnostics to
demonstrate that the fan is operational.
Table 8. Diagnostic and maintenance functions
Function code Diagnostic or maintenance function Instructions location
Exit Maintenance Mode: Causes the drive to become
available for reading and writing data.
“Function code 0: Maintenance mode”
on page 28
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 28
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 29
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 30
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 30
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 31
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 32
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 33
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 33
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 is presented
last.
“Function code 9: Display error code
log” on page 34
Clear Error Code Log: Erases the contents of the
error code log.

log” on page 34
