[Summary] building system on one E250 for another

Just got a couple of replies.

While there were other suggestions, we don't have a lot of servers, 
don't do rebuilds that often, and the overhead of setting up some of the 
alternatives as well as learning how to do them isn't worth it (although 
it might be fun if we had the time to spare).

The information I needed came from Thomas Carter of memc who said he had 
done this numerous times. He said the different prom versions had not 
presented a problem for him and that a reconfiguration reboot should 
take care of differences in graphics and scsi cards.

It will take a while to do this, because we have a couple dozen 
applications that have to be updated, built and configured as well as 
accounting for user data that will come up when the drives are finally 
moved to the intended system. If I come up with any additional 
information that seems important, I will post an addendum to this 
summary after we are done.

I have two E250's. One in production (a), the other available to build 
(b). We need to rebuild both, but minimize the downtime on (a).

We need to update the OS and application configuration on (a) from 
Solaris 7 to 9. We have two new 72G drives to replace the old 9G boot 
drive and another 18G drive. All other slots are full and there is an 
external drive cage that is full as well. Those are all user or 
application data.

My idea is to put the 72G drives in (b) in the exact slots that they 
will replace in (a), build the system on (b), preconfigure /etc/vfstab 
to account for the additional drives on (a), then swap the new drives 
into (a) and do a reconfigure boot. We would also change a few things in 
/etc such as /etc/hostname.hme0 before shutting down and swapping drives 
to account for the identity change into the other system. [Oh, before 
building the new 72G drives on (b), I would remove and label (sticky 
notes) all the existing internal drives on (b), and put them back in 
later for it's own rebuild.]

Is there any reason this wouldn't work?

There are some slight differences between the two machines (bought about 
2 years apart). I put the prtdiag -v at the end of my message for both. 
The memory is different, which shouldn't matter. The video cards look to 
be different, and the PCI SCSI cards are different. We will be 
rebuilding the external drive cage to be LVD to match the newer PCI SCSI 
card which will also get installed into (a). Also, the System PROM 
revisions are slightly different. All this shows in the prtdiag.

TIA
