Hi -
From: Bill Gunshannon <bill(a)cs.scranton.edu>
I am trying to put 2.11 on one of my 11/44's. I picked up the RL02/RK
images from the archive. I put the RL02 images on real RL02's (Yes,
some of us still have and use them!! :-) My intent was to boot this
RL drives were reliable (compared to RA81 and RK06/7 drives) if not
exactly spacious ;)
3 RL02 disks
A CDU/720-TM SCSI Controller with 4 MAXTOR 340M disks and a QIC tape
Now the problem.
The system boots fine. And it will mount /dev/rl1a. But it won't mount
/dev/rl2a. I get "/dev/rl2a on /vol2: No such device or address".
What rev of the kernel do you have? First line in /VERSION should
have the magic number.
I get the same error when I try to do a disklabel.
What's more, I also
get this same error when I try to access any of the RA devices. I am
using the GENERIC Kernel which I assume has all the devices in it.
Anybody have any suggestions??
What I think is happening is that the system is only configured for
2 RL drives - the change from 2 to 4 happened quite late (patch #439
I think).
The RA problem sounds like the MSCP driver either isn't in the
kernel or wasn't probed/attached at boot time. You can see if
MSCP support's present with something like 'nm -g /unix | grep _raintr"
and seeing if you "040364 T _raintr" for the interrupt handler. If
you do get that then check /etc/dtab for a line like:
ra ? 172150 0 5 raintr # uda50, rqdx1/2/3
The '0' for the vector says for the probe/attach logic to assign
a vector and tell the controller what value was used. You could put
anything in there (154 or 150 I think is the assigned value for the
first MSCP controller).
If none of that works then I'm stumped as to why the RA drives can't
be accessed.
Good Luck.
