The sdo/sdn devices are the local scsi disks (there are some more multipathed FC disks) the md devices were installed on.

RHEL 7.6, kernel 4.14.0-115.17.1.el7a.ppc64le

Hi Peter, no worries! I've CC'd in the Petitboot mailing list too to add some extra eyes.

What Petitboot version are your servers running? (Usually located at the top of the screen). It's possible Petitboot is being a bit simplistic in its RAID detection and you're helping it along with the extra mdadm call.
Also if you run the pb-sos tool from the command line it will collect up a bunch of relevant logs which we can have a look at.

Cheers,
Sam
