virtual_scsi_disk

Use the "virtual_scsi_disk" mapping for disk containers and physical disks. This is the most convenient way of connecting disks to SCSI adapters in CHARON-VAX

...

Warning

Unlike MSCP controlled disk images, a disk image connected to a SCSI controller as a virtual SCSI disk CANNOT be replaced by another disk image unless "removable" parameter is set for this particular disk image.

Example:

set pka_0 container = "/charon/disks/my_removable_disk.vdisk"
set pka_0 removable = true

virtual_scsi_tape

Use "virtual_scsi_tape" for tape containers. This is the most convenient way of connecting tapes to SCSI adapters in CHARON-VAX.

...

Parameter

container[N]

N=0…7

Type

Text String

Value

A string containing the full path to a tape container. If the specified tape image does not exist, CHARON-VAX creates it.

If only the name of the tape container is specified, CHARON-VAX will look for the container in the folder CHARON is running from.

Warning

If the "CHARON Guest Utilities for OpenVMS" (CHARONCP) package is used there is a possibility not to specify the exact tape container on CHARON start since it can be specified later using the package.

In this case the syntax is:

load virtual_scsi_tape/chscsi pka_0 scsi_bus=pka scsi_id=0
set pka_0 container[0] =".vtape"


media_type

Parameter

media_type[N]

N=0…7

Type

Text String

Value

Overrides PRODUCT ID in the default SCSI INQUIRY data.

Valid values may contain uppercase letters, integers and spaces. Length of this string cannot exceed 16 characters.

By default the PRODUCT ID returned is "TLZ04"

...

set pka_0 container = "/charon/tapes/tape1.vtape"
set pka_0 media_type = "TLZ08"

virtual_scsi_cdrom

Use "virtual_scsi_cdrom" to connect IDE or SATA host CD-ROM or *.iso file to CHARON-VAX.

...

This example associates an unallocated CD-ROM drive "/dev/sr0" with virtual_scsi_cdrom "pka_0".

physical_scsi_device

Use "physical_scsi_device" to connect any host "raw" SCSI device to CHARON-VAX. This mapping type is suitable only for tape drives and other specific SCSI devices connected to CHARON host.

...

This example associates a host tape device "/dev/sg3" with physical_scsi_device "pka_0".
