Hi Scott. I am grateful for and honored by your response. I am pretty much stuck with the asr device for now, but I would love a list of quality hardware raid devices and related management utilities that can be used with freebsd/linux. I can get raidutil (sysutils/asr-utils) to recognize a tape drive that was not present during boot by direct inquiry (raidutil -I d0b1t6d0). Unfortunately, camcontrol rescan all will not see the device unless it was present at boot. If I boot with one tape drive attached, power it down, camcontrol rescan all (and confirm that it is gone), attach a different tape drive (use the appropriate raidutil -I d0b1t#d0 command to tell the asr0 where the tape drive can be found), a camcontrol rescan of the bus with the tape drive never returns nor can it be killed. If anyone wants more data or testing on that, I'll be happy to do what I can. I can accept that the issue is the vendor/hardware (asr) and not the software (freebsd). Thanks for pointing me in the right direction.
