If the cartridge is in the drive at power-on, portions of POST are not executed.
If possible (doesn’t apply to power off), the drive responds with CHECK CONDITION status
(sense = Not Ready – Logical Unit has not Self-Configured) until all tests have completed
successfully.
If an error condition occurs and if possible (as above), an error code (reference the “Error Codes
Table” on page 62 ) is displayed on the SCD and is transferred through the Fibre Channel or
SAS bus in response to the next command.
Maintenance Mode Diagnostics
This section provides a summary of the Maintenance mode options.
Display Code Maintenance Function
None Normal Mode
0 Function Code 0: Maintenance Mode : Causes the drive to become available for
reading and writing data.
1 Function Code 1: Run Drive Diagnostics : Runs tests to determine whether the drive
can properly load and eject cartridges, and read and write data.
2 Function Code 2: Update Drive Firmware from FMR Tape : Loads updated firmware
from a field microcode replacement (FMR) tape.
3 Function Code 3: Create FMR Tape : Copies its field microcode replacement (FMR)
data to a customer-supplied scratch (blank) data cartridge.
4 Function Code 4: Force a Drive Dump : Same as Eject button pressed for 10 or
more seconds, except it doesn’t cause a Reset.
5 Function Code 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.
6 Function Code 6: Run Host Interface Wrap Test : Performs a check of the circuitry
from and to the connector.
7 Function Code 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.
8 Function Code 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.

time (the codes are ordered; the most recent is presented first and the oldest
(tenth) is presented last).
A Function Code A: Clear Error Code Log : Erases the contents of the error code log.
C Function Code 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.
E Function Code E: Test Cartridge and Media : Performs tests to ensure that a
suspect cartridge and its magnetic tape are acceptable.
F Function Code F: Write Performance Test : Performs tests to ensure that the drive
can read from and write to tape.
