Creation of CHARON-AXP configuration file

Using the above info, the following configuration can be created:

...

#
# First RQDX3 controller on address 772150
#
load RQDX3/RQDX3 DUA address=017772150
set DUA container[0]="C:\My disks\rz23.vdisk"
set DUA container[1]="C:\My disks\rz24.vdisk"

#
# Second RQDX3 controller on address 760334
#
load RQDX3/RQDX3 DUB address=017760334
set DUB container[2]="C:\My disks\rz25.vdisk"
set DUB container[3]="C:\My disks\rz26.vdisk"

#
# First TQK50 controller on address 774500
#
load TQK50/TQK50 MUA address=017774500
set MUA container[0]="C:\My tapes\tape1.vtape"

#
# Second TQK50 controller on address 760444
#
load TQK50/TQK50 MUB address=017760444
set MUB container[3]="C:\My tapes\tape2.vtape"

#
# First DHQ11 controller on address 760500

load virtual_serial_line/chserial TXA0 port=10010
set TXA line[0]=TXA0

#
# Second DHQ11 controller on address 760520
#
load DHQ11/DHV11 TXB address=017760520
load virtual_serial_line/chserial TXB0 port=10011
set TXB line[0]=TXB0

#
# DESQA controller on address 774440
#
load DESQA/DEQNA XQA address=017774440 interface=XQA0 load packet_port/chnetwrk XQA0 interface="connection:Charon"

...

Note the Qbus addresses specification: The number is prefixed with "0", meaning it is an octal value. The number of digits reflects the 22 bit Qbus architecture.

Additional DHQ11 serial lines can be mapped later. For now, only 2 lines are configured. They are mapped to IP ports 10010 and 10011.

DESQA is mapped to a network interface having the name "Charon". This interface will be used for CHARON-AXP (see the Installation section for more details) on this particular host.

Making disk images

In our example, possible mappings of RQDX3 and TQK50 tapes include physical devices and disk and tape images. Tape images should not be manually created, whereas you have to provision disk images, as described below.

Our example creates disk images of the original physical type. In reality, this step is the best opportunity in the migration to provision bigger disks to get extra storage space.

Create special directories for storing disk and tape images, as needed. Created directories are referenced in the sample configuration file above.

...> 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:

Image Removed

The main dialog of the utility will appear:

Image Removed

Select "HP Alpha" in the "Select System" drop-down menu, "MSCP" 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

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:

Image Removed

The "MkDisk" utility will create the requested disk image:

Image Removed

Repeat this sequence for the disks "RZ23.vdisk", "RZ25.vdisk" and "RZ26.vdisk". Put them in the same "C:\My disks" folder.

Installation of HP Alpha operating system

The next step is to transfer the data from the source HP Alpha system to CHARON-AXP. The easiest way to do this is via backup over the network. But for this operation we need a bootable, network-enabled operating system on a CHARON-AXP disk image or physical disk.

The example configures the CHARON-AXP MicroHP Alpha 3600 system for installation of HP Alpha/VMS from a distribution CD-ROM (usually it is "\\.\CdRom0" if the host has only one CD-ROM drive):

#
# First RQDX3 controller on address 772150 with addition of 3 units: a disk for HP Alpha/VMS, storage disk and CD-ROM drive
#
load RQDX3/RQDX3 DUA address=017772150
set DUA container[0]="C:\My disks\rz23.vdisk"
set DUA container[1]="C:\My disks\rz24.vdisk"set DUA container[2]="C:\My disks\new_vms_system.vdisk"
set DUA container[3]="C:\My disks\backup_storage.vdisk"
set DUA container[4]="\\.\CdRom0"

DUA3 will be the disk where all the source disks will be copied, so its size needs to be big enough to store all the disk backup images

Create an empty disk image for installation of HP Alpha/VMS and another one for storing backups from the source HP Alpha system as it is shown in the section above.

Run CHARON-AXP and boot from "dua4" ("migration.cfg" is the configuration file we use in this example):

Installation of HP Alpha operating system

The next step is to transfer the data from the source HP Alpha system to CHARON-AXP. The easiest way to do this is via backup over the network. But for this operation we need a bootable, network-enabled operating system on a CHARON-AXP disk image or physical disk.

The example configures the CHARON-AXP AlphaServer ES40 system for installation of HP OpenVMS from a distribution CD-ROM (usually it is "\\.\CdRom0" if the host has only one CD-ROM drive):

# # DEC-KZPBA SCSI controller is mapped to 5 disk containers; one of them (DKA300) - for migration purposes; # another one (DKA400) - for installation of fresh HP OpenVMS system from distributive
#

load KZPBA PKA scsi_id = 7

set PKA container[0] = "C:\My disks\bootable.vdisk"
set PKA container[100] = "C:\My disks\RZ22.vdisk"
set PKA container[200] = "C:\My disks\RZ23.vdisk" set PKA container[300] = "C:\My disks\migration.vdisk" set PKA container[400] = "C:\My disks\fresh_openvms.vdisk"

#
# CD-ROM for HP OpenVMS installation (DQA0)
#

set ide container="\\.\CdRom0"

DKA300 will be the disk where all the source disks will be copied, so its size needs to be big enough to store all the disk backup images

Create an empty disk image for installation of HP OpenVMS and another one for storing backups from the source HP Alpha system as it is shown in the section above.

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

...>es40.exe migration.cfg

P00>>>boot dqa0

Install HP Alpha/VMS including DECnet on "dua2dka400". DECnet address must belong to the same area as the source HP Alpha system.

Login to the newly installed VMS OpenVMS system and initialize the disk intended for backups storage. Let's assume it's prompt is "newvms$ "

newvms$ INIT DUA3DKA300: SCRATCH
newvms$ MOUNT/SYSTEM/NOASSIST DUA3DKA300: SCRATCH

Back to Table of Contents

...

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 "source$ "

...

HP Alpha whose prompt is set to "source$ "

source$ BACKUP/IMAGE/IGNORE=INTERLOCK DKA0: 1.400::DKA300:[000000]DKA0.BCK/SAVE
source$BACKUP/IMAGE/IGNORE=INTERLOCK DUA0INTERLOCK DKA100: 1.400::DUA3DKA300:[000000]DUA0DKA100.BCK/SAVEsource$ BACKUP/IMAGE/IGNORE=INTERLOCK DUA1 DKA200: 1.400::DUA3DKA300:[000000]DUA1DKA200.BCK/SAVE SAVE

Once the backup procedure completes, the disk "DUA3DKA300" of CHARON-AXP will contain 2 3 savesets: "DUA0"DKA0.BCK", "DKA100.BCK" and and "DUA1DKA200.BCK"

Back to Table of Contents

...

Next, restore the new savesets to their corresponding virtual disks. Login to CHARON-AXP and issue this sequence of commands to restore all the savesets created on the previous step:

newvms$ MOUNT/FOREIGN DUA0DKA0:
newvms$ BACKUP/IMAGE DUA3DKA300:[000000]DUA0DKA0.BCK/SAVE DUA0DKA0:
newvms$ DISMOUNT DUA0DKA0:

newvms$ MOUNT/FOREIGN DKA100:
newvms$ BACKUP/IMAGE DKA300:[000000]DKA100.BCK/SAVE DKA100:
newvms$ DISMOUNT DKA100:

newvms$ MOUNT/FOREIGN DUA1 DKA200:
newvms$ BACKUP/IMAGE DUA3DKA300:[000000]DUA1DKA200.BCK/SAVE DUA1DKA200:
newvms$ DISMOUNT DUA1DKA200:

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 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.
