SUMMARY: RAID 410 host adapter driver not loading !!

I had problems loading the RAID Host adapter file ptisp.o on boot up.
Actually it turned out that the problem was with the actual adapter card.
Apparently there are 2 different types of host adapter cards. The
difference is seen when:

ok, show-sbus

command is issued. The output for the 2 cards are different.

one says:

        slot 1 ptisp

the good card should say:

        slot1 PTI, ptisp

I think it has to do with the level of operating system too. We are still
on SunOS 4.1.4.

The DEC Hardware Engineer who swapped the card fortunately knew this.


My many thanks to the following helpful souls who responded to my post:
