I bought a couple IBM DFHS-31080 drives from ONSALE a few weeks ago
and I've been unable to talk to them as anything but the whole-drive.
Here is the dmesg description from an ss20 running 1.4:

  probe(esp0:4:0): max sync rate 10.00Mb/s
  sd1 at scsibus0 targ 4 lun 0: <IBM, DFHS, 18> SCSI2 0/direct fixed
  sd1: 1074MB, 4385 cyl, 4 head, 125 sec, 512 bytes/sect x 2199878 sectors

and here is my label:

  # /dev/rsd1c:
  type: SCSI
  disk: DFHSS1F
  label: 
  flags:
  bytes/sector: 512
  sectors/track: 125
  tracks/cylinder: 4
  sectors/cylinder: 500
  cylinders: 4385
  total sectors: 2192500
  rpm: 7200
  interleave: 1
  trackskew: 0
  cylinderskew: 0
  headswitch: 0		# milliseconds
  track-to-track seek: 1	# milliseconds
  drivedata: 0 

  8 partitions:
  #        size   offset     fstype   [fsize bsize   cpg]
  a:   134000        0     unused        0     0         # (Cyl.    0 - 267)
  b:   268000   134000       swap                        # (Cyl.  268 - 803)
  c:  2192500        0     unused        0     0         # (Cyl.    0 - 4384)
  d:  1790500   402000     unused        0     0         # (Cyl.  804 - 4384)

Yet I can only "newfs" the "c" partition (i.e. full-drive) and I get this
for say the "a" partition:

  ss20# newfs /dev/rsd1a
  newfs: /dev/rsd1a: open: Device not configured

Ditto for partition "d".  I saw the same behavior on an Alpha box with
a "bha" controller also running 1.4.

Is the drive doing something funky or am I doing something stupid?
