Everything works except the M8061. Jumpers are set to Factory default.
I did add the Q22 jumper just in case. There is always a chance its a bad
controller card.
The drive will come on line but that's about it. If I try to boot from it. i
get
an
error, 'no controller' . If its running under RT11, booted off the RX02 , I
get
'cant read directory '
Any words of wisdom out there
Thanks, Jerry
What are the CSR's for the RX02 controllers? Any chance you have two set the
same? I assume you have a drive # >plug in the front of the RL02 drive?
Not to sure how the RX02 card is set right now, would have to look
tonight. I will try the system with out the RX02 card also.
The Drive ID Plug is set to drive 0
Also, do you have another RL02 drive to test as
well?
Yes, thats on my list. Does the system consider the RL02 drive and
M8029 controller card as one ??? Or does 'controller not found" mean
much.
The M8029 and the M8061 are totally separate devices and do NOT interact
with each other. The standard CSR,VECTOR for each are totally different.
If both are working correctly, you can remove one or the other and still
operate.
IMPORTANT!!!!!!!!!
A BA23 has the top 3 slots ABCD. The other 5 slots are ABAB and must be
filled to provide bus continuity up to that point in the chain. An
RQDX1 MUST
be the last board in the chain since it does not provide bus
continuity. Unused
slots at the end of the bus grant chain are not a problem and can remain
empty.
If you remove the M8029, move up the M8061 and the M8639 boards one slot
since you can't leave the 3rd slot empty.
BUT, if you place the M8061 in the 3rd slot, on a BA23, the M8029 will
require
a bus grant card in the dual slot beside it in the 4th quad slot or the
M8639 below
it will not work. If the M8639 in an RQDX2 (an RQDX2 is an M8639-YB),
then you can place the M8639-YB in the 4th slot and the M8029 in the far
right of the 5th slot - otherwise you will require an M9047 in the far
right of the
5th slot if the M8029 is in the far left of the 5th slot.
The configuration you have right now with slot 2 and slot 3 half filled
is correct.
Each of the dual boards in slot 2 and slot 3 are on the extreme left
which is correct.
If the boards were not in the correct place, you could not boot with the
RX02.
Since you have
an RQDX1 or RQDX2, you may be using a BA23 box.
Otherwise, how have you connected your hard drive? And can you use
your hard drive on the M8639 controller?
Even with a BA23, since the M8029 is in the third slot, there should not
be a problem with the M8061, especially if the M8639 is working.
Yes it is a BA23 box and the M8639 does boot the RX50 and Hard drive.
It also boots from the RX02
Since the RX02, RX50 and Hard drive all boot, I would suggest
that the RL02 hardware seems to have an isolated problem. After
you boot RT-11, perform:
SHOW DEVICE
command and see if the M8061 controller has been recognized.
Since you have strapped the M8061 as the factory setting, it
should be at the standard CSR and VECTOR. RT-11 will display:
"Not installed"
if the M8061 is not recognized (something is not working). If:
"Installed"
is displayed, then the M8061 is being recognized, although that
does not mean the M8061 is working correctly. Which you
obviously realize, but are asking for help in determining what
exactly is the problem:
(a) M8061 controller
(b) RL02 drive
(c) Cables
(d) Rl02 pack
While cables may be OK, it is possible to connect them backwards.
If I remember correctly, when that happens, the RL02 RED fault
light is on - unless it is burned out. Of course, one of the cables
could have a broken wire. At this point, it seems like you have the
RL02 isolated as the problem, but you will need help from a hardware
individual to figure out the best way to solve the problem. BUT, be
very careful since a bad pack can damage a drive which then damages
other packs.
