Adding tape devices to the systems emulated by Charon-HPA emulated HP3000 or HP9000 system PAR is a process consisting of several steps:
- Link the tape container files and/or physical tape devices with the corresponding HP3000 or HP9000 configuration paths in the Charon configuration file and load the devices.
- Enable the tape for use by the guest operating system.
...
The new emulated tape device must be added to the configuration file of the Charon-HPA PAR instance. This requires two commands:
...
The following example adds a SCSI tape device with device path 0/0/1/0.6.0 (controller A, SCSI target ID 6, LUN 0) to the configuration:

Using Tapes on MPE/iX Guest Systems
Displaying Tape Characteristics on MPE/iX Systems
You can use the SYSGEN > IO to display tape characteristics as shown in the following example for LDev 7:
Using :DEVCTRL
in HP3000to Load and Eject a Tape on MPE/iX Systems
:DEVCTRL is an HP-supplied script that allows several aspects of physical tape devices to be controlled: in-drive data compression, tape loading, and automatic tape eject. This script is also used with Charon-HPA PAR to load virtual tape image files. When :DEVCTRL is used to load a virtual tape file, it causes Charon-HPA PAR to create (if necessary) and open the virtual tape file configured in the Charon-HPA PAR configuration file.
The :DEVCTRL syntax is show below:
