Need help booting Sun 3/160 from SCSI disk

[DOUG O'NEAL]

I am just now starting to manage a Sun 3/160 and am having some problems.
We just got a SCSI disk (equivalent to a a SUN0669) and we want to change
the boot device from xy0 (Fujitsu-M2333) to sd0.  I did the following:

1) dump 0f - /dev/xy0a | (mount /dev/sd0a /mnt; cd /mnt; restore -r -)
2) cd /usr/mdec; installboot -vlt /boot bootsd /dev/sd0a
3) sync; sync; shutdown -h now
4) b sd() -s

The response from the boot command is a SCSI device timeout.  I can boot
from xy() with the -a flag and place the root partition on sd0a with no
problems.  Is it possible to have the SCSI disk as the boot device?  If
so, what am I doing wrong?

Thanks in advance,
