The source VAX configuration in this example is:

To find out the exact types of controllers please refer to documentation on the source VAX system.

...

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]="/my_disks/rz23.vdisk"

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.

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

$ mkdir /my_disks
$ mkdir /my_tapes

Next, create disk images using the "mkdskcmd" utility:

$ mkdskcmd -d rz24 -o /my_disks/rz24.vdisk
Please wait...
100% done
Success.
$ mkdskcmd -d rz25 -o /my_disks/rz25.vdisk
Please wait...
100% done
Success.
$ mkdskcmd -d rz26 -o /my_disks/rz26.vdisk
Please wait...
100% done
Success.
$ mkdskcmd -d rz27 -o /my_disks/rz27.vdisk
Please wait...
100% done
Success.

The example configures the CHARON-VAX MicroVAX 3600 system for installation of VAX/VMS from a distribution CD-ROM:

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

Create an empty disk image for installation of VAX/VMS and another one for storing backups from the source VAX system:

$ mkdskcmd -d rz27 -o /my_disks/new_vms_system.vdisk
Please wait...
100% done
Success. $ mkdskcmd -d rz59 -o /my_disks/backup_storage.vdisk Please wait... 100% done Success.

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

$ mv3k6 migration.cfg
KA650-A V5.3, VMB 2.7
Performing normal system tests.
40..39..38..37..36..35..34..33..32..31..30..29..28..27..26..25..
24..23..22..21..20..19..18..17..16..15..14..13..12..11..10..09..
08..07..06..05..04..03..
Tests completed.
>>>boot dua4

Install VAX/VMS including DECnet on "dua2". DECnet address must belong to the same area as the source VAX system.

Initialize the disk intended for backups storage:

$ INIT DUA300: SCRATCH
$ MOUNT/SYS/NOASSIST DUA300: SCRATCH

Issue (let's assume that the CHARON-VAX system is node 1.400 in this example):

$ BACKUP/IMAGE/IGNORE=INTER DUA0: 1.400"username password"::DUA3:[000000]DUA0.BCK/SAVE
$ BACKUP/IMAGE/IGNORE=INTER DUA1: 1.400"username password"::DUA3:[000000]DUA1.BCK/SAVE
$ BACKUP/IMAGE/IGNORE=INTER DUB0: 1.400"username password"::DUA3:[000000]DUB0.BCK/SAVE
$ BACKUP/IMAGE/IGNORE=INTER DUB1: 1.400"username password"::DUA3:[000000]DUB1.BCK/SAVE

Once the backup procedure completes the disk "DUA3" of CHARON-VAX will contain 4 savesets: "DUA0.BCK", "DUA1.BCK", "DUB0.BCK" and "DUB1.BCK"

...

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

$ MOUNT/FOR DUA0:
$ BACKUP/IMAGE DUA3:[000000]DUA0.BCK/SAVE DUA0:
$ DISMOUNT DUA0:

$ MOUNT/FOR DUA1:
$ BACKUP/IMAGE DUA3:[000000]DUA1.BCK/SAVE DUA1:
$ DISMOUNT DUA1:

$ MOUNT/FOR DUB0:
$ BACKUP/IMAGE DUA3:[000000]DUB0.BCK/SAVE DUB0:
$ DISMOUNT DUB0:

$ MOUNT/FOR DUB1: $ BACKUP/IMAGE DUA3:[000000]DUB1.BCK/SAVE DUB1: $ DISMOUNT DUB1:

Now reboot CHARON-VAX and boot from the same boot disk as you do on the source VAX system.

...

Connect SCSI tape drive to CHARON-VAX host via PCI card
- Map the tape drive in CHARON-VAX configuration file
  a. Restore source VAX system backups from tape to disk images via VAX/VMS running on CHARON-VAX
  b. Boot from standalone backups and restore its content to CHARON-VAX virtual disks
- Dump source VAX system backups to tape images with "mtd" utility and:
  a. Boot from freshly installed VAX/VMS system and restore the tape images to CHARON-VAX virtual disks
  b. Boot from standalone backups and restore its content to CHARON-VAX virtual disks
Create a network cluster between the source VAX system and CHARON-VAX (it is possible to use the source system as boot server); then simple backup from one disk to another:
$ BACKUP/IMAGE/IGNORE=INTER REAL$DUA0: DUA0:
