Dell Powervault 120T / ADIC FastStor DLT D116

[Brian A. Seklecki]

I just connected a Dell Powervault 120T to an Adaptec AHA-2944 HVD ("High 
Voltage Differential") controller and the resulting dmesg indicates what 
is probed by my RELENG_5_3 kernel:

ahc0: <Adaptec 2944 Ultra SCSI adapter> port 0xe400-0xe4ff mem 
0xe9001000-0xe9001fff irq 5 at device 11.0 on pci0

sa1 at ahc1 bus 0 target 4 lun 0
sa1: <ARCHIVE Python 06240-XXX 8040> Removable Sequential Access SCSI-3 
device
sa1: 40.000MB/s transfers (40.000MHz, offset 32)
pass0 at ahc0 bus 0 target 0 lun 0
pass0: <ADIC FastStor DLT D116> Removable Changer SCSI-2 device
pass0: 3.300MB/s transfers


For some reason, the tape changer is probing as pass(4) instead of ch(4).


Any ideas why?  SCSI devices have a "device class" designation, IIRC. 
However, I can't get useful debugging out of camcontrol(8) w/ recompiling 
the kernel w/ DEBUG options.

I'm going to do that now, but any ideas would be appreciated.
