When restoring mksysb images, I've seen a "estore

the 1, 2 & 3 prompt (#2 is to review & change
install/restore options, with 3 you go to maintenance
state), I've always chosen "No" but I bet this will
restore the system to its "precise" state as when the
backup was performed, along with tcpip aliases and
static routes defined on the ODM.

As of the aio0 getting in the defined state, same
thing happens to the iocp0 device (required by Lotus
Notes).

already - but I don't think you have any cause for
concern.

Subject: Cloning a system via mksysb ...


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.
