scsi2ide adapter not recognized as sd*

[Olaf Schreck <chakl@syscall.de>]

Hi,

I have a Sparc20 with an external SCSI case that has a SCSI2IDE adapter 
and a 40GB IBM IDE drive.  This drive is not recognized as sd*, but as 
uk0 instead.

Snippet from dmesg (3.2 GENERIC plus options SCSIDEBUG DDB_SAFE_CONSOLE, 
full dmesg at the end):

esp0 at dma0 offset 0x800000 pri 4: ESP200, 40MHz, SCSI ID 7
scsibus0 at esp0: 8 targets
scsi_inqmatch: 9/0/0 <IBM, DCAS, >
scsi_inqmatch: 2/0/0 <, , >
sd0 at scsibus0 targ 3 lun 0: <IBM, DCAS-34330W, S65A> SCSI2 0/direct fixed
sd0: 4134MB, 8205 cyl, 6 head, 171 sec, 512 bytes/sec, 8467200 sec total
uk0 at scsibus0 targ 5 lun 0: <SCSIDE, , > SCSI2 3/processor fixed

scsi_inqmatch: 2/5/1 <, , >
cd0 at scsibus0 targ 6 lun 0: <TOSHIBA, XM-4101TASUNSLCD, 1084> SCSI2 5/cdrom removable

>From sd(4) I understand that the drive gets attached to uk0 because the 
probing doesn't recognize it as type "direct".  Any chance of forcing it 
to get recognized as sd1?  I have played with UKC> trying to hardcode the 
sd0/sd1 targ/lun values, no avail.  Maybe I need to specify the drive 
geometry, but how?  Google showed some dmesgs that had SCA drives 
recognized as uk0 ... SCSI2 3/processor as well, but no follow-ups on that.

I had the same device (IDE disk + SCSI2IDE adapter) working with a IRIX 6.5 
box (newfs, mount, copy stuff) without problems, and a friend of mine had 
this adapter working with Linux or Solaris, as well.  I also tried it with 
an OpenBSD 3.2/i386 machine, same result, no go.


Pointers welcome, thanks,
chakl
