Place the drive in maintenance
mode
Ensure that the drive is unloaded. Then, within two seconds,
press the Unload button three times. The drive is in
maintenance mode when the Ready light is flashing and 0
appears in the SCD.
Note: While in maintenance mode, the drive does not accept
host interface commands.
Note: If you attempt to enter Maintenance Mode with a
cartridge in the drive, the drive will rewind and eject the
cartridge. Remove the cartridge and repeat the steps for
entering Maintenance Mode.
Scroll through the maintenance
functions
While in maintenance mode, press the Unload button once per
second to increment the display characters by one. When you
reach the character of the diagnostic or maintenance function
that you want (see Diagnostic and Maintenance Functions
on
page 44), press and hold the Unload button for three seconds.
Exit maintenance mode Press the Unload button once per second to increment the
display character until 0 displays. Then press and hold the
Unload button for three seconds. Maintenance mode is exited
when the Ready light is On and the SCD becomes blank.
Force a drive dump (part of the
maintenance mode)
Caution: If the drive detects a permanent error and displays an
error code, it automatically forces a drive dump (also
known as a save of the firmware trace). If you force a
drive dump, the existing dump will be overwritten
and data will be lost. After you force a drive dump,
do not turn off the power to the drive or you may
lose the dump data.
Choose one of the following procedures:
• If the drive is in maintenance mode (Ready light is flashing
and Fault light is On for Maintenance mode), refer to
Function Code 4: Force a Drive Dump
on page 52.
• If the drive is in operating mode (Ready light is On or
flashing), press and hold the Unload button for ten seconds.
If captured dump data exists, the drive places it into a dump
area (for information about retrieving the data, see Procedure
1: Determining Firmware Level and Capturing Drive Dump on
page 81).
