scsi_bus

Name of the emulated SCSI disk controller: "pka" or "pkb"

scsi_id

A value between 0 and 7. This is the ID number of the emulated SCSI device. The SCSI adapter is preloaded with address 7. If required, set it to another value in the range of 0-7 from the VAX console.

container[N]

N=0…7

Text String

media_type[N]

N=0…7

Text String

Overrides the PRODUCT ID in the default SCSI INQUIRY data.

Valid values may contain uppercase letters, integers and spaces. The length of the string cannot exceed 16 characters.

If not specified, synthetic SCSI INQUIRY data is returned containing a PRODUCT ID selected based on the disk size.

Initially left unspecified.

geometry[N]

N=0…7

Text String

This formatted string value specifies the explicit geometry of the disk storage element

The string format is <X>”/”<Y>[“/”<Z>] where:

• "X" is the number of sectors per track;
• "Y" is the number of tracks per cylinder;
• "Z" (optional) is the number of cylinders on the unit. If omitted, Z is calculated based on X, Y and the total number of sectors on the unit that reflects the size of the disk storage element;

If this parameter is not set, CHARON-VAX will configure the geometry based on the most probable disk type.

use_io_file_buffering[N]

N=0…7

Enables use of the host OS I/O buffering.

Initially set to “false” (buffering disabled).

removable[N]

N=0…7

Initially set to “false” (fixed, non-removable).

media_type[N]

N=0…7

Text String

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"

geometry[N]

N=0…7

Text String

Specifies the size of the tape image and (optionally) the size of the "early-warning" area at the end of the tape image.

Syntax:

where:

• <image-size> is the tape size in MB

• <early-warning-zone-size> is the size (in KB) of the space remaining on the tape when a warning to the OS is issued. If omitted, 64K is assumed.

Example:

container[N]

N=0…7

Text String

A string containing the device name to map to the emulator.

• ISO images
  • [<path-name>"/"]<file-name>[".iso"]
    

    Format: A string containing the full path to an *.iso image.

    If only the name of the *.iso image is specified, CHARON-VAX will look for it in the folder CHARON is running from.
    .

• CD-ROM or DVD drives
  • "/dev/cdrom<X>" or
  • "/dev/sr<X>" where X is 0,1,2...

This parameter is initially not set, thus creating NO storage elements on the controller

media_type[N]

N=0…7

Text String

Overrides the PRODUCT ID in the default SCSI INQUIRY data.

Valid values may contain uppercase letters, integers and spaces. The length of the string cannot exceed 16 characters.

If not specified, synthetic SCSI INQUIRY data is returned containing a PRODUCT ID selected based on the disk size.

Initially left unspecified.

The string format is <X>”/”<Y>[“/”<Z>] where:

• "X" is the number of sectors per track;
• "Y" is the number of tracks per cylinder;
• "Z" (optional) is the number of cylinders on the unit. If omitted, Z is calculated based on X, Y and the total number of sectors on the unit that reflects the size of the disk storage element;

If this parameter is not set, CHARON-VAX will configure the geometry based on the most probable disk type.

use_io_file_buffering[N]

N=0…7

Enables use of the host OS I/O buffering.

Initially set to “false” (buffering disabled).

container[N]

N=0…7

Text String

A string containing the device name to map to the emulator.

• Physical tape drives and other SCSI devices connected to CHARON host including the tape changers
  • "/dev/sg<X>", where X is 0, 1, …

media_type[N]

N=0…7

Text String

Overrides the PRODUCT ID in the default SCSI INQUIRY data.

Valid values may contain uppercase letters, integers and spaces. The length of the string cannot exceed 16 characters.

If not specified, synthetic SCSI INQUIRY data is returned containing a PRODUCT ID selected based on the disk size.

Initially left unspecified.

use_io_file_buffering[N]

boolean

Enables use of the host OS I/O buffering.

Initially set to “false” (buffering disabled).

removable[N]

N=0…7

Initially set to “false” (fixed, non-removable).

disconnect_timeout[N]

N=0…7

Sets logical unit disconnect timeout. This parameter helps if a connected SCSI device performs a given SCSI command for a very long time.

The default value depends on the type of the SCSI device attached. For example for a disk it is 10 seconds, for a tape - an hour. If the type of the device is not known the timeout is 1 hour.

Example with 48 days timeout:
