Re: Removing (unconfigured) disks from RAID-5 array?

First of all "unconfigured" and "in the System ASP" are incompatible
terms. If they are unconfigured they should appear in:
STRSST
3. Work with disk units
1. Display disk configuration
4. Display non-configured units

Are you sure they are in the same parity set?

If they are only two drives of this size then I suspect they are not in a
raid set. They might be mirrored. On some units you can put a few drives
in the CEC. I've seen two drives, mirrored, this way and the rest of the
drives were in one or more raid sets.
Let's look at another of our lpars on a different rack:
