Hello Managers:

Just for experimental purposes, I have taken a dump of /root and /usr of an
ES-40 server which disks are from an HSZ80 array controller and restored the
dumps to another server that did not have an array controller. Obviously
different hardware; the disks were of the same size of both servers.
Obviously, restoring a dump from one server to another server with different
hardware can cause obstacles. My question is, is this possible and what are
the preliminary steps that I need to do if I want to do this in the near
future?

With the following steps below, it restored the root.dump however when I
rebooted the server into single user mode to start restoring the /usr, it
went to an infinite loop of trying to boot. Below are the steps and messages
upon booting.
----------------------------------------------------------------------------
--------------------------
boot with the cdrom
mount a advfs file system to /mnt
copy the root.dump and the usr.dump to /mnt/dump directory.
cd /mnt
vrestore -xvf /mnt/dmp/root.dump
it restores.
umount /mnt
sync
sync
shutdown -h now
>>set boot_osflags -s
>> boot
----------------------------------------------------------------------------
-------------------------

What happens here that it will start to boot into a loop with the following
error:

bootdevice_parser: unknown protocol name 'SCSI'
setconf: Bootdevice parser failed to translate bootdevice SCSI 1 1 0 0 0 0
0.
panic (cpu 0): setconf: bootdevice_parser failed

DUMP: No primary swap, no explicit dumpdev.
          Nowhere to put header, giving up.

halted CPU 0

halt code = 5
