[parisc-linux] 712/80 - 7cdroms - scsi prbl

[Sorin Ghinescu]

Hi guys,
I'm trying to install parisc-linux on 712/80.
I don't know if this is actually an OS problem or a hardware problem but
you may have experienced it and could help me.
I'm booting from my external cd-rom but it seems that the kernel is
fooled by something because it creates 7 cd-rom devices for all the scsi
targets available leaving no room for the hd. If I switch the cd-rom off
then I get 7 hds!
Has anyone experienced this?
Thanks
Sorin

Check and make sure that none of your scsi ids are conflicting, don't
forget the controller is at id 7. Also check your cables and termination.
If it still doesn't work try a different hard drive.

I've had this happen too, but it was on a Sun Ultra 30. The problem was
that the computer didn't recognize the CDROM correctly. Trying a different
cdrom may fix the problem... It did for me.

This typically means the HD is set to the same SCSI ID as the
interface controller (NCR 53c710 logic on LASI). Host ID is
7 by default. Verify the HD is set to something else.

It's possible the lasi scsi driver is broken and setting the
initiator to 0 (or something other than 7).

Perhaps ---

This is a classic symptom of a SCSI device set with the same address as the
SCSI controller - normally 7 in a narrow SCSI environment.
Change the address of the CDROM to 4
You need to identify the CDROM SCSI address jumpers. (usually 3 pairs of
adjacent pins with plastic shorting jumpers on. If all three have jumpers
then it is likely the device is set to address 7. remove the middle jumper -
this will change it to address 4. There may still be a conflict with another
device , but the seven drives should "go away"

Oops,

"will change it to address 5"
