Re: AS/400e 170 IPL failure

In this case minuscule is indeed approaching zero. :-(

With IBM i and it's predecessors RAID 1 is referred to as Mirroring. So 
because he is seeing RAID sets it's RAID 5. (Recall RAID 6 showed up 
with MUCH newer hardware than this old 170!) With Mirroring the drives 
on their own appear unprotected but the ASP itself is flagged Mirrored. 
There will also be two drives #1 and two #2 etc.

I honestly think the previous owner pulled a couple drives as spares or 
to repair another machine and the system ASP is a gonner.
