Unloading Cartridges
The tape drive must be powered on to unload a cartridge tape. Normally, the cartridge
is unloaded by the unload command from the system. If the tape is positioned at EOT,
a 5190 tape drive takes approximately 60 seconds to rewind the tape and unload the
cartridge and a 5194 tape drive takes approximately 1 second or less. To unload a
cartridge using the drive front-panel controls, use the following procedure:
1. Press the RESET button. The message panel shows NT RDYU or NT RDYF.
These are the NOT READY drive states. See NOT READY States on page 4-30
for more information.
2. Press the UNLOAD button to eject the cartridge. During unloading, the
UNLOADNG message appears on the message panel. If the tape needs
rewinding, the drive automatically begins rewinding the tape and the REWINDNG
message appears. When the tape is unloaded, the AUTO MODE WAS
INTERRUPTED message appears.
3. Press RESET to clear the message.
When a cartridge cannot be unloaded successfully, the message panel returns an error
code or message. If this happens, press RESET and then UNLOAD. When the drive
has recovered from the error state, the cartridge is ejected. If power is removed from
