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 a "show config" command 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: Cypress PCI Peripheral Controller

Bus 00 Slot 07: Function 1: PCI IDE

Bus 00 Slot 07: Function 2: PCI IDE

Bus 00 Slot 07: PCI USB

Bus 00 Slot 08: DECchip 21052 PCI to PCI Bridge

Bus 01 Slot 08: ISP1040 Scsi Controller
pka0.7.0.1008.0 SCSI Bus ID 7
dka0.0.0.1008.0 RZ2DD-KS
dka400.4.0.1008.0 RRD45

>>>

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

Bus number
Slot number
Function number

...

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

$ mkdskcmd -d rz24 -o /my_disks/rz24.vdisk
Please wait...
100% done
Success.
$ mkdskcmd -d rz23 -o /my_disks/rz23.vdisk
Please wait...
100% done
Success.
$ mkdskcmd -d rz22 -o /my_disks/rz22.vdisk
Please wait...
100% done
Success.
$ mkdskcmd -d rz28 -o /my_disks/bootable.vdisk
Please wait... 100% done
Success.

Login to the source HP Alpha system. Stop all the batch queues, kick off the users, stop all application applications and close databases if any. 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 this is normal.

...

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 DKA0:
newvms$ BACKUP BACKUP/IMAGE DKA300:[000000]DKA0.BCK/SAVE DKA0:
newvms$ DISMOUNT DISMOUNT DKA0:
newvms$ MOUNT/FOREIGN FOREIGN DKA100:
newvms$ BACKUP/IMAGE DKA300:[000000]DKA100.BCK/SAVE DKA100:
newvms$ DISMOUNT DKA100:
newvms$ MOUNT/FOREIGN FOREIGN DKA200:
newvms$ BACKUP/IMAGE DKA300:[000000]DKA200.BCK/SAVE DKA200:
newvms$ DISMOUNT DKA200:

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).
