Link device with tape container file

or

physical tape device

MKXnnn.image="/path/to/tape-container-file"

 The path can point to an existing tape container file, but this is not mandatory. The emulator can create the container file if required.

MKXnnn.image="/dev/stXN"

You can identify the Linux tape device name using the command dmesg |grep -i tape.
X N stands for the device number, e.g., /dev/st0.

MKXnnn.autoload=yes

 Multi-volume backup does not work correctly when autoload is enabled. If a new tape is requested by the software, it will not wait for a new tape to load but overwrite the existing file. If data is must be written to several tapes, this needs to be configured manually, e.g., by a customized script.

 Without autoload enabled, MPE/iX can load a tape using the DEVCTRL command. There is no such option for HP-UX guest systems. The autoload command can help to overcome this deficiency. Please note the note above!
