The "ncu" ("Network Control Utility") is used to dedicate a host interface to CHARON-AXP, to release it back to the host and to manage CHARON virtual interfaces (TAPs).

The utility allocates chosen network interfaces (both physical and virtual) and configures the offload parameters.

Dedication of a host physical interface to CHARON

Login as root and enter "ncu". The following menu will appear:

:> 8

The utility lists available network interfaces (both physical and virtual) and indicates whether they are dedicated to the host or to CHARON and whether they are currently in use by host operating system.

"ncu" offers several options:

  1. Dedicate interface to CHARON
  2. Release interface to host
  3. Create a bridge between a chosen physical network interface and the Linux virtual network and create a number of virtual network interfaces 
  4. Remove the Linux virtual network and all the created virtual network interfaces 
  5. Add VLAN interface
  6. Remove VLAN interface
  7. Print status  - use it to display status of network interfaces and the menu shown above
  8. Exit

In the example above we see 2 network interfaces - "eth0" and "eth1", both of them are dedicated to host, but host uses only the interface "eth0".

Let's dedicate the interface "eth1" to CHARON-AXP.

Enter "1", then type "eth1" and press Enter:

...

Specify the interface to dedicate to CHARON:eth1
Turning off offloading for eth1.. Please wait

select action:

1 - Dedicate to CHARON 
2 - Release to host
3 - Create Bridge with TAPs
4 - Remove Bridge
5 - Add VLAN
6 - Remove VLAN
7 - Print status
8 - Exit

:> 7

Now the interface "eth1" is dedicated to CHARON-AXP:

Enter "8" to return to console prompt.

Now "eth1" can be used by CHARON-AXP.

In the example above we see 2 virtual network Interfaces "tap0" and "tap1" connected to the created bridge. The physical network interface "eth1" is used for the bridge to the virtual network interfaces.

The interfaces "tap0" and "tap1" are ready to be used in CHARON configurations - they do not need to be additionally dedicated to CHARON.

The "CHARON Guest Utilities for OpenVMS" (CHARONCP) package contains several utilities for managing virtual tapes, changing the emulator speed and creating useful definitions for that operations.

This set of utilities is located in the "charoncp011.vdisk" disk file in the "/opt/charon/disks".

Back to Table of Contents

Installation

Specify this image in the CHARON configuration file, boot from the system disk and mount the disk with the following OpenVMS command:

...

* Are you satisfied with the backup of your system disk [YES]? YES
* Where will the distribution volumes be mounted: <device name>:[000000.CHARONCP011.KIT]

Enter the products to be processed from the first distribution volume set.
* Products: CHARONCP011

Select all the components included to the package:

...

Component Selection

Select the CHARONCP components you wish to install from the menu below.
An asterisk appears next to the packages that have already been
selected. You can remove a package from the list by selecting it
again. You may enter more than one selection by separating your
choices with commas.

1. [*] CHARONCP Guest Utility (REQUIRED)
2. [*] Compatability Utilities
3. [*] Install DCL Commands & Help

4. Exit

* Your choice [4]: 4

Proceed with installation using all the default options.

Once the installation is completed, add the following line to the "SYS$STARTUP:SYSTARTUP_VMS.COM" ("SYS$STARTUP:SYSTARTUP_V5.COM" for VMS 5.5) file for the package to be loaded automatically at system startup:

...

After that the package will be loaded automatically on startup.

Performance optimization

CHARON takes 100% of host CPU even in case of idle state of guest OpenVMS operating system. To get rid of such resources consumption there is a specific option provided by CHARON Guest Utilities - "idle" mode.

...

Loads the OpenVMS idle loop detection software. This allows CHARON to detect when the emulated CPU(s) are idle and use the host power saving instructions to reduce power usage.

...

Virtual tapes management

Specify mapping to tape container in the following way in the CHARON configuration file:

...

Example:

...

Once it is done using the following commands it is possible to manage virtual tapes attached to CHARON:

...

Create the specified host-file (if it does not already exist) and attach it to the specified virtual tape device.

Example:

$ CHARONCP SET MAGTAPE MKA600: /LOAD="backup_01.vtape"

...

Detach any file currently attached to te specified virtual tape device.

Example:

$ CHARONCP SET MAGTAPE MKA600: /UNLOAD

Possible errors:

...

The filename specified as a value to the qualifier /LOAD was either too long or does not have a file extension of ".vtape".

...

Attempting to execute a SET MAGTAPE/LOAD when a file is already attached.

Perform a SET MAGTAPE/UNLOAD first. If a SET MAGTAPE/LOAD command has not previously been executed, then the CHARON configuration container specification for the tape device may contain a full path. Doing this will create and attach and initial tape container file. To avoid this, remove the file name from the specification (leaving only a fileextension of ".vtape" and optional directory).

(info) If some tape container has been already specified in the CHARON configuratioon file use the command "CHARONCP SET MAGTAPE <device> /UNLOAD" to unload it first.

Defining keys

It is possible to define certain keys on the terminal keyboard for fast access to the CHARONCP functionalilty while you are in CHARONCP:

...

$ CHARONCP
CHARONCP> DEFINE /KEY <key-name> <equivalence-string>

...

Defines an equivalence string and a set of attributes with a key on the terminal keyboard.

You can have a set of keys defined automatically for use with the CHARONCP utility by placing DEFINE/KEY commands in the file SYS$LOGIN:CHARONCP_KEYDEFS.INI

Example:

$CHARONCP
CHARONCP> DEFINE /KEY F1 "SET MAGTAPE MKA600: /UNLOAD"

...

Displays key definitions created with the DEFINE/KEY command. Refer to the DCL help entry for SHOW KEY for further information.

Example:

$CHARONCP
CHARONCP> SHOW KEY F1
DEFAULT key state definitions:
F1 = "set magtape mka600: /unload"
CHARONCP>

(info) For more information refer to the OpenVMS DCL Dictionary (DEFINE/KEY section).

Displaying version

...

Displays the CHARONCP package version number and architecture. This can be useful for customers reporting issues with the CHARONCP software.

Example:
