I don't have any knowledge on ANS and how to boot from RAID card,
but If I were you, I would make sure installboot is correctly
done on the root device and if it seems to be done right, 
I would type just
  0 > boot /pci1/dac960/sd@8:0
                            ==
But I am afraid wrong partition input (in your case netbsd 
instead of 0), may be ignored and 0 will be used, so, 
your boot command may be fine.

So please do the installboot manually.
Unfortunately (at lease to me) the installboot has been changed
from 1.5 to 1.6, you have to be carefull.

What I did recently, was:
-------------------------------------
# cd to /usr/mdec
# umount /dev/wd0a
# installboot -v -t ffs /dev/rwd0a bootxx /boot
File system:         /dev/rwd0a
File system type:    ffs (blocksize 8192, needswap 0)
Primary bootstrap:   bootxx
Secondary bootstrap: /boot
Bootstrap start sector: 4
Bootstrap byte count:   1764
Bootstrap block table:  118 entries of 8192 bytes available, 8 used: 2128 2144 2160 2176 2192 2208 2224 2106
Writing bootstrap
-------------------------------------
(installboot = /usr/sbin/installboot,
Ok you have not booted yet, just boot from CD and do
the equivalent work of above. probably starting with

mount /dev/sd0a /mnt
mount /dev/sd0d /mnt/usr
cd /mnt/usr/mdec
./installboot ......
