Hi All--

I'm trying to clone a V210 to a V100--I've ufsdumped the root partition,
installed the bootblock successfully, but it's locking up after displaying
the spinning cursor:

Sun Fire V100 (UltraSPARC-IIe 500MHz), No Keyboard
OpenBoot 4.0, 2048 MB memory installed, Serial #51591265.
Ethernet address 0:3:ba:13:38:61, Host ID: 83133861.

Executing last command: boot -s

SunOS Release 5.9 Version Generic_117171-02 64-bit
Copyright 1983-2003 Sun Microsystems, Inc. All rights reserved.
Use is subject to license terms.
/

From what I understand, at this point the bootblk and ufsboot have
successfully loaded. /sbin/rcS hasn't loaded yet (I modified it to echo a
startup message) so I think that means there's a problem loading the kernel
or starting init. /etc/system and vfstab are correct as well.

Any idea why this isn't working, between two machines with the same
architecture? Is there anything I can do to debug this startup?

At this stage, the system is loading device drivers. You might try
using a -v boot to see which drivers have loaded.

Ah thank you, that's helpful. It appears to be freezing just before it
enumerates (?) the processors. On a V100 I would get:

...
su0 at ebus0: offset 0,3f8

su1 at ebus0: offset 0,2e8

cpu0: UltraSPARC-IIe (portid 0 impl 0x13 ver 0x14 clock 500 MHz)
...

On the cloned system it locks up just before this:

...
su2 at ebus1: offset 0,3f8

su3 at ebus1: offset 0,2e8

(freeze)

A real V210 has UltraSPARC-IIIi's whereas the V100 uses UltraSPARC-IIe's. I
didn't think there was anything processor-specific in a particular
installation, am I wrong?

Thanks,

Yes. "Cloning" systems this way, unless the models are pretty
much identcal, is a recipie for disaster at worst, or a waste
of time at best.

You probably copied /etc/path_to_inst.

If you want to clone to different systems, the only supported
way to do so is "flarcreate" (and install the other system from
the flash archive created)

I wouldn't have thought so, and the processors don't generally have the
device specific files required by other drivers.

Nonetheless, it appears that such is possible with a Solaris
installation. Have you tried using flash archives?

That was the problem, thanks! I will look into flash archives for future
non-emergency restores.

Thanks Casper and Darren for the helpful info!
