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.

You are, of course, correct. I was misremembering how RAID 5 worked.
Two dead drives and it's shot. Degraded has often panned out well for
me, but if this is RAID 5 it's beyond degraded.

The only faint hope that is left is that while I'm assuming that it's
using RAID5, I don't know how to verify that. So there's a miniscule
chance that it's using mirroring (or RAID 1) instead. Said chance is
likely vanishingly small, however.

The work with disks functionality is very limited, when you D IPL to
the DST, so I'm not sure how to look into that.
