Many thanks to Thomas Blinn for his explanation of what's going on.
It turns out that devices that report WWID capability but do not ensure
WWID uniqueness violate relevant SCSI standards. The reason CAM fails
is simply because it was designed to be used with Working disks.
Generally running LSM & AdvFS on such devices is not recommended,
since they both rely heavily on WWID.
However, with this newfound knowledge I managed to google a solution
posted two years ago by Jay Nash. This is perfectly fine for me since
it is a testbed system.
# Add this to /etc/ddr.dbase, run ddr_config -c
# Force CAM to use BTL WWID.

Type = disk
Name = "CSC" # Your nasty vendor goes here.
