You may loose special hardware tuning params that you may have had in your
env when the devices are "rediscovered". For example num_cmd_elems on an
HBA would get reset.

When you recover a mksysb image, at the point where you select the new boot
disk, one of the options is to "Recover Devices", which by default is set
to No.

As a result you lose any customizations that you made, which generally are
ethernet and aio.

This past weekend, I cloned one system (a 7017-S80) to another (a
9133-55A), by making a mksysb DVD of the S80, and restoring it to the
55A.

The process worked wonderfully, and we've now retired our long-
serving but aged S80, but there were a couple of things that I didn't
expect:

* I lost all of the en0 settings. I guess that makes sense, though;
wouldn't want the new system to come up with the same IP addresses as
the old system.

* aio0 came up as "defined", and not "available"; this caused me a
major freak-out, as oracle refused to load. Five minutes of panicked
googling found me the answer, so it wasn't too bad.

I guess my question is, might there be something else that I missed?
The SAN disks have been re-zoned to this new system, the volume
groups imported and mounted, and everything appears to be running
better and faster then it ever had. Just a bit nervous that
something I didn't catch might bite me in the near future.
