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.

Creating CHARON Virtual Machine

...

Specify the HP Alpha model to be emulated and the name of the VM then press the "Create" button:

The VM will be created:

Making disk images

In our example, possible mappings the mapping of the KZPBA SCSI controller include disk and tape images. The tape images have not to be manually created whereas the disk images have to be created 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 larger disks to get extra storage space.

Create special directories for storing the disk and tape images. Created The created directories are referenced in the sample configuration file above.

...

Start the "MkDisk" utility by pressing the "Virtual Disk Tool" button in the "Host Information & Utilities" tab of the CHARON Virtual Machines Manager:

The following dialog 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.

Press then the "Create Disk Image" button:

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

Repeat this sequence for the disks "RZ28.vdisk", "RZ22.vdisk" and "RZ23.vdisk". Place them in the same folder.

Installation of HP Alpha operating system

...

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

...

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

P00>>>boot dqa0

Install HP Alpha/VMS including DECnet on "dka400". The DECnet address must belong to the same area as the source HP Alpha system.

...

newvms$ INIT DKA300: SCRATCH
newvms$ MOUNT/SYSTEM/NOASSIST DKA300: SCRATCH

Making remote backups

Now we are ready to create the disk backups of the source HP Alpha system on the CHARON VM.

...

Login to the source HP Alpha system. Stop all the batch queues, kick off the users, stop all the applications and close the databases if there are. The commands listed in SYS$MANAGER:SYSHUTDWN.COM may be helpful. The goal is to close as many files as possible. The system disk will have several files opened (pagefile, swapfile, etc.) but and this is a normal situation.

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

In this example, the CHARON VM system is node 1.400.

Issue the following commands from the source HP Alpha. Let's assume its prompt is "source$ ":

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

Once When the backup procedure completesoperation will be completed, the disk "DKA300" of the CHARON VM will contain 3 savesets: "DKA0.BCK", "DKA100.BCK" and "DKA200.BCK"

Restore backups to CHARON-AXP disks

The NIC can be disabled with a interface="(disabled)" statement in the CHARON VM configuration file.

Alternative ways of data transfer

...

Connect a SCSI tape drive to the CHARON-AXP host via a PCI card
- Map the tape drive in the CHARON VM configuration file
  a. Restore the source HP Alpha system backups from tape to disk images via OpenVMS running on the CHARON VM.
  b. Boot from standalone backups and restore the content to the CHARON VM virtual disks
- Dump the source HP Alpha system backups to tape images with using the "mtd" utility and:
  a. Boot from the freshly installed OpenVMS system and restore the tape images to the CHARON VM virtual disks
  b. Boot from the standalone backups backup and restore the content to the CHARON VM virtual disks
Create a network cluster between the source HP Alpha system and the CHARON VM (it is possible to use the source system as a boot server); then perform simple backup backups from one disk to another:
$ BACKUP/IMAGE/IGNORE=INTERLOCK REAL$DKA0: DKA0:
