After the cartridge is partially inserted, the drive mechanism automatically
completes the cartridge insertion process and properly positions the tape within
the drive.
The yellow and green rectangular LEDs on the front panel turn ON as the drive
checks the cartridge to determine its state (blank, write-protected, prerecorded
audio, firmware update, etc.) and then positions to the data area, which typically
takes about 10–12 seconds.
2. Start the software application and issue a command.
For example, if you want to back up a file, issue the appropriate command or
make the appropriate menu selections from the backup application software.
The drive begins initializing the tape before completing the backup (WRITE)
operation.
3. After completing the backup and the yellow rectangular LED on the front panel
is OFF, push the eject (tape unload) button on the front panel to remove the
cartridge.
The drive buffer then empties to tape, the tape rewinds and the system log is
updated.
After being ejected, the cartridge rests in the cartridge insertion slot in a half-
way position for easy removal.
The sequence for writing a cartridge that already contains data is virtually the same
as the blank cartridge sequence with the exception that the cartridge initialization
process is not necessary.
A brief delay occurs as the cartridge is inserted while the drive identifies the
cartridge type and state, and then positions to the data area.
Another technological advancement incorporated into the Scorpion 24 drive is flash
memory, which is useful if the drive's SCSI firmware needs to be upgraded. With the
permanently installed, electrically upgradeable flash memory, revised SCSI firmware
for the drive can be loaded using any one of three methods: 1) Seagate OEM
firmware cartridges (see Chapter 4); 2) through the host SCSI bus; and 3) through
the drive serial port (see Chapter 8).
The flash memory feature enables qualified OEMs who need to revise Scorpion 24
SCSI firmware to do so quickly and easily. Flash memory also prolongs the life cycle
of a drive because many new techniques—such as increasing the capacity of the
drive through support for longer tapes—may require only a firmware upgrade.
