What kind of FC storage devices are they? Plain FC disks, or some kind
of RAID, "array controller", or enclosure device?

Open-source OSes do a pretty poor job at handling anything but bare
disks. Even for bare disks, they typically fail to probe all the
potential IDs of a "modern" FC topology, and may fail to probe high
LUN numbers (exact limit depending on OS.

Still, NetBSD is about as good as Linux or FreeBSD of the same vintage.
