Physical Disks on Controllers

[Michael Blinn]

Hold that thought - It looks like OMSA is reporting incorrectly. In the
BIOS, the physical and virtual drives are defined correctly, with 2
disks in a virtual drive, and the remaining 5 on the second controller
in a virtual drive at RAID5.

Is this a problem that others have seen, where drives appear to be
misreported in the incorrect enclosure?
