Summary

Original Question:

Lads,

I have an Ultra1 that I need to dump across to a 220R.  What command do I
use to detect and display the hardware version of the source (Ultra1),  I
know that Hardware version 5/98 has the required PCI drivers, but prior
versions do not.  Any help or suggestions would be great.

There where a couple, but Thorfinn Rasmussen and Casper Dik nailed it.   The
info I needed
was in the /etc/release file.

Some said try uname, and man uname, but that gives patch versions, and
processor type,  but
not the info I needed.  prtvconf, dmesg and sysdef where also recommended,
but did
not bear the fruit as I needed the X/XX number of hardware (month / year)

I was advised by a someone from Sun, that dumping from an Ultra1 to a 220R
may not work, and their official position is not to recommend it.  But I
like to cheat so oh well :)

Thanks to all that answerd,  To many to list.  Casper made a couple
additional points so his mail is attached below.

For your information this is how I intend on rebuilding the device tree.
Comments are welcome.

# cd /mnt/devices ; rm -r *
# cd /mnt/dev/dsk ; rm *
# cd /mnt/dev/rdsk ; rm *
# cd /mnt/dev/rmt ; rm *
# rm /mnt/etc/path_to_inst

The above destroys the device tree restored from dump

# drvconfig -r /mnt/devices -p /mnt/etc/path_to_inst
# cd /devices
# find . -print | cpio -pdum /mnt/devices
# disks -r /mnt
# devlinks -r /mnt
# ports -r /mnt
# tapes -r /mnt

cat /etc/release

However, be aware that the /dev* trees and /etc/path_to_inst and others
do not match and need to be chanegd also.

If you need to copy the system over, you can copy the disk image over,
nuke /etc/path_to_inst and even possibly parts of /devices (all except
pseudo) and then run *upgrade* which will put most things right.
