Is there any difference in manually upgrading a system with raid drives from a system with single drive ? Does one drive have to be rebuilt manually and the second one imaged ?

not really an answer to the question but some useless info on the topic:
A collegue of mine swears that if he manually loads software onto 3300 with dual drives, without mirroring before hand the system installs on both drives.
I've never checked this but have queried him on this on several occasions and every time he swears he does this often and works.

I have observed that if both drives are installed into a brand new system and you load the software before mirroring it will load to both drives and they will be mirrored at the end of the exersize.
That being said, the process in the Tech Handbook specifically says to Mirror BEFORE loading the software.
I compromise by running the system initially (During Setup) on a single drive and Mirror at the end of the work day.
To Answer the original question again:
For systems where downtime absolutely must be minimized. I remove the Mirrored Drive just prior to upgrading the system. I upgrade the Primary drive and if everything goes well, I re-install the Mirror. If everything does not go well and I need to restore back to original I remove the primary and boot up on the backup Mirrored drive.

Ofcourse very logic but who does it.
