About this task
Note: If the cartridge in the drive is an INPUT tape that contains ACTIVE or 'ONLY COPY' data (there is
no backup), eject commands that are issued at the host fail to unload the tape, and power-cycling the
drive fails to eject the cartridge, make no further attempts to unload this tape. Call Technical Support
and open a PMR if one is not already open, to initiate the process of sending the drive with the loaded
cartridge in for recovery.
