Unload button
The Unload button completes several functions.
The Unload button ( 1 in
) is used to rewind cartridges, utilize Maintenance mode, force a memory dump, or reset the drive.
Table 1. Functions that the Unload button completes
Unload Button Function
How to Initiate the Function
Rewind the tape into the
cartridge and eject the
cartridge from the drive
Press Unload. 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.
Place the drive in
Maintenance mode
Ensure that the drive is unloaded. Then, within 2 seconds, press Unload three times. The drive is in Maintenance mode when the Ready
light is flashing and displays in the SCD.
Notes:
While in Maintenance mode, the drive does not accept host interface commands.
If you attempt to enter Maintenance mode with a cartridge in the drive, the drive rewinds and ejects the cartridge. Remove the
cartridge and repeat the steps for entering Maintenance mode.
Scroll through the
Maintenance functions
While in Maintenance mode, press Unload 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
), press and hold Unload for 3
seconds.
Exit Maintenance mode Press Unload once per second to increment the display character until displays. Then, press and hold Unload for 3 seconds.
Maintenance mode is exited when the Ready light is On and the SCD becomes blank.
Force a drive memory
dump (part of the
Maintenance mode)
Attention: If the drive detects a permanent error and displays an error code, it automatically forces a drive memory dump (also known
as a save of the firmware trace). If you force a drive memory dump, the existing memory dump is overwritten and data is lost. After you
force a drive memory dump, do not turn off the power to the drive or you might lose the memory dump data.
Choose one of these procedures:
If the drive is in operating mode (Ready light is On or flashing), press and hold Unload for 10 seconds.
If captured memory dump data exists, the drive places it into a memory dump area (for information about retrieving the data, see
Procedure 1: Determining firmware level and capturing drive dump
).
Reset the drive
Press and hold Unload until the drive begins the reset procedure (Fault light turns On when reset starts).
Note: If a tape cartridge is loaded in the drive, it unloads the tape.
Repeat the "Reset the drive" procedure after the tape is unloaded. The drive saves a memory dump of the current drive state, then
reboots to allow communication. Do not cycle power as this action erases the contents of the memory dump.
Inserting a tape cartridge
To insert a tape cartridge:
1. Ensure that the drive is powered-on.
2. Ensure that the write-protect switch on the tape cartridge is properly set (see
).
