| Type of mapping | Description |
|---|
| "<file-name>.vdisk" | Mapping to files representing physical disks of the VAX system (disk images).
These files can be created from scratch with "mkdskcmd" utility. Data and OS disk backups are transferred from the original system via tapes or network and restored into these container files.
Mapping may also include the full path, for example: "/my_disks/my_boot_disk.vdisk" |
| "/dev/sdNL" | Mapping to physical disks. "L" is letter here. Be careful not to destroy all the information from the disk dedicated to CHARON-VAX by mistake! These disks can not be formatted by the host OS. It is also possible to use not a whole disk, but previously created partitions on it. In this case the syntax is the following: "/dev/sdLN" where N is the number of partition to be used. |
| "/dev/srN" | Mapping to CD-ROMs. There are some variants of this mapping: "/dev/cdrom<N>" or "/dev/cdrom" |
| "<file-name>.iso" | Mapping to an ISO file for reading distribution CD-ROM images. |

SCSI controller NCR53C94
The VAX 4000 and MicroVAX 3100 have an NCR53C94 SCSI controller onboard for support of different types of SCSI devices including disks and tapes. Optionally a second controller can be added.

| Mapping Object | Description |
|---|
| virtual_scsi_disk | Mapping to a file representing VAX disk (disk image) on the host physical disk: - "<file-name>.vdisk"
These files can be created from scratch with "mkdskcmd" utility. Data and OS disk backups are transferred from the original system via tapes or network and restored into these container files. Mapping may also include the full path, for example: "/my_disks/my_boot_disk.vdisk"
- "/dev/sdL" - name of a physical disk. Be "L" is letter here. Be careful not to destroy all the information from the disk dedicated to CHARON-VAX by mistake! These disks can not be formatted by the host OS.
It is also possible to use not a whole disk, but previously created partitions on it. In this case the syntax is the following: "/dev/sdLN" where N is the number of partition to be used.
|
| physical_scsi_device | Mapping to a host SCSI device: - "/dev/sgN" - name of the SCSI device for direct mapping, for example, a SCSI disk or tape reader.
|
| virtual_scsi_cdrom | Mapping to a host CD-ROM (not only SCSI) or to ISO image: - "/dev/sr<N>", "/dev/cdrom", "/dev/cdrom<N>" - name of host CD-ROM drive
- "<file-name>.iso" - name of ISO image. It may contain the full path, for example: "/my_disks/vms_distributive.iso"
|
| virtual_scsi_tape | Mapping to a file representing tape (tape image). It may contain a path, for example: "/my_tapes/backup.vtape" |
