This section describes how to migrate your HP Alpha system to CHARON-AXP. We will use a sample HP AlphaServer ES40 system running OpenVMS to demonstrate the migration procedure. The process is similar for all CHARON-AXP models.

The source HP Alpha peripheral configuration in this example is:

Controller	Devices on controller	Description
KZPBA	-DKA0 (

Info

In case of Tru64 UNIX V5 running on the host system it is recommended to use the following commands to get information on the host configuration:

Command	Description
`#/sbin/hwmgr view devices`	Get detailed information about the host hardware configuration
`#/sbin/hwmgr show scsi`	Get specific information about the host SCSI controllers and attached disks
`#/sbin/hwmgr view hierarchy`	Get information about the host controllers

Please reference to the Tru64 UNIX User's Guide for more details.

Info

In some particular situations it is also important to know the exact placement of all the peripheral devices on HP Alpha PCI bus. To get that information issue "show config" command in at ">>>" prompt of HP Alpha console, for example:

>>>show config

...

PCI Bus

Bus 00 Slot 03: DECchip 21142 Network Controller
ewa0.0.0.3.0 00-00-F8-03-9A-6D

Bus 00 Slot 07: Function 1: PCI IDE

Bus 00 Slot 07: Function 2: PCI IDE

The "show config" command allows to collect collects the following information of placement of peripheral devices on PCI bus:

Making disk images

In our example, possible mappings of KZPBA SCSI controller include disk and tape images. Tape images should have not to be manually created , whereas you have to provision disk images, as described below.

...

...> cd C:

\
C:\> mkdir "My disks"

C:\> mkdir "My tapes"

This operation can also be done using Windows Explorer.Next, create disk images using the "MkDisk" utility.

Start the "MkDisk" utility from the "Start" menu to create disk images:

Div

class	pagebreak

The main dialog of the utility will appear:

...

Select "Alpha AXP" in the "Select System" drop-down menu, "SCSI" in the "All Controllers" drop-down menu and "RZ24" (for example) in the "Select Disk Type" drop-down menu, then press "Create Disk Image" button:Image Removed.

Div

class	pagebreak

Press then the "Create Disk Image" button:

Image Added

Div

class	pagebreak

The utility will ask you to specify the output file name. Select the "C:\My disks" directory created just before (or create it directly in the dialog) and press "Save" button:

...

Repeat this sequence for the disks "RZ28.vdisk", "RZ22.vdisk" and "RZ23.vdisk". Put Place them in the same "C:\My disks" folder.

Installation of HP Alpha operating system

...

Run CHARON-AXP and boot from the CDROM named "dqa0" ("migration.cfg" is the configuration file we use in this example):

...

The use of the "SHOW DEVICE /FILES" command would be of help to know files opened on a disk

Issue (letLet's assume that the CHARON-AXP system is node 1.400 in this example). Issue then the following commands from the source HP Alpha . Let's assume it's login is whose prompt is set to "source$ "

source$ BACKUP/IMAGE/IGNORE=INTERLOCK DKA0: 1.400::DKA300:[000000]DKA0.BCK/SAVE
source$BACKUP/IMAGE/IGNORE=INTERLOCK DKA100: 1.400::DKA300:[000000]DKA100.BCK/SAVEsource$ BACKUP/IMAGE/IGNORE=INTERLOCK DKA200: 1.400::DKA300:[000000]DKA200.BCK/SAVE

...

If you are going to have CHARON-AXP and the original physical HP Alpha on the network at the same time, you must change the network identity of one (usually the CHARON-AXP).

The easiest way is to boot the CHARON-AXP virtualized system on the restored system disk with the network Disabled and configure new addresses, as needed. The NIC can be disabled with a "connection:disabled" statement in the CHARON cfg configuration file.

Then Enable the network and reboot.
