How to Initiate the Function
Press the Unload Button once. The Ready light flashes while the drive is rewinding
and unloading.
Note: During a rewind and eject operation, the drive does not accept host interface
commands.
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.
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 3-6), press and hold the Unload Button for three seconds.
Press the Unload Button once per second to increment the display character until
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.
Attention: 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:
v 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
3-11.
v 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 5-1).
Press and hold the Unload Button until the drive begins the reset procedure (Fault
light will turn On when reset starts).
Note: If a tape cartridge is loaded in the drive the drive will unload the tape. Repeat
the "Reset the drive" procedure after the tape is unloaded. The drive saves a dump of
the current drive state, then reboots to allow communication. Do not cycle power as
this will erase the contents of the dump.
