Re: 8203-E4A RAID5 vs. ASP protection

Isn't another option to IPL into DST, turn off RAID, then turn RAID back on
and just leave off the offending disk?

Yup, the asterisks just show the drive is not added to an ASP (of any

type). In order to remove that drive from the RAID set, you would need to
manual IPL into DST.

That's what I want to try out next.

I’m not sure which controller you have but back in the day the minimum

number of drive units was four, so I doubt it will let you remove that
drive from the RAID set.

SST says, it's a 57B3-001. If I remember right that was some E4A
speciality together with a special backplane.

Hope not being a strategy is an axiom, but here’s hoping your system

does not go castors up until after it’s no longer needed…

I know and I'm aware. This is a deliberate decision carefully considering
the relative importance of the system. I promise I will not complain if
things break. ;-)

:wq! PoC
