We do this all the time.  You can just move the drives over to the other
chassis without any changes or any issues.

The HP RAID controllers are really smart about this - the configuration
is stored on both the RAID controller and the drives - it checks both on
startup and figures out what is right based on what it sees.  If things
don't all match it may prompt you to tell it which is right, but if all
the drives match each other it will go with what the drives say it
should be.  

We take advantage of this in our strategy for handling hardware
failures.  We have hot spare machines sitting in the racks and if a
production server fails for any reason we swap the chassis with a hot
spare - that way we get the server back up and running in the shortest
time possible - we can muck around with the bad chassis later.

Subject: swapping HDs in servers


Been awhile since I done this... any reason this shouldn't work?

I have an HP ML350 G3 server (about 3-4 years ago) that is acting up.  I
think it's hardware related.  I have an unused (retired) HP ML350 G3
server laying around.  I'd like to take the (2) physical hard drives
from the problematic server (configured as RAID1) and install them in
the unused retired server.  

I'm thinking the second server should recongnize a RAID1 configuration
on the drive and boot up without a problem.  

Any problems with this theory?
