Table 4. Functions that the unload button performs (continued)
Unload button function How to initiate the function
Exit Maintenance Mode
Press the unload button once per second until
0
displays. Then, press and hold the
unload button for three seconds. Maintenance Mode is exited when the status LED
becomes solid green and the SCD becomes blank.
Force a drive dump (part of
the Maintenance Mode)
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 might
lose the dump data.
Choose one of the following procedures:
v
If the drive is in Maintenance Mode (status LED is solid amber), refer to “Function
Code 4: Force a drive dump” on page 24.
v If the drive is in Operating Mode (status LED is solid or flashing green), 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 “Obtaining a drive dump” on page 52).
Reset the drive Press and hold the unload button until the drive begins the reset procedure (SCD will
display random patterns and the status LED will be amber).
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.
Inserting a tape cartridge
Before you begin
Attention: Do not leave the tape cartridge in the drive when the drive is inactive
or when the power is off. Otherwise, the tape cartridge might be damaged.
About this task
To insert a tape cartridge:
Procedure
1. Ensure that the drive is powered-on.
2. Ensure that the write-protect switch on the tape cartridge is properly set.
3.
Grasp the cartridge so that the write-protect switch faces you (see
1
in
Figure 6 on page 15).
4. Slide the cartridge into the tape load compartment.
Note:
a. If the cartridge is already in an ejected position and you want to
reinsert it, remove the cartridge then insert it again.
b. If the cartridge is already loaded and you cycle the power (turn it off,
then on), the tape will reload.
c. Do not attempt to load a cartridge when the drive is in Maintenance
Mode until the drive requests it.
