Hi,

It seems that the DAC960 has been a hot topic so I thought i would see
if anyone has had the same problems as me.

I have an AS2000 4/275 (single CPU).

My first problems were with a DAC960PD which i upgraded to the 2.73
firmware as that is all it would take. However when i tried insmod the
DAC960 module it gave me the following (under 2.4.18preXX and 2.2.20):


DAC960: ***** DAC960 RAID Driver Version 2.2.11 of 11 October 2001 *****
DAC960: Copyright 1998-2001 by Leonard N. Zubkoff <l...@dandelion.com>
DAC960#0: Unable to map Controller Register Window for Controller at
DAC960#0: PCI Bus 0 Device 8 Function 0 I/O Address a000 PCI Address 0x0

I have mailed the author and he seemed to think that the problem was
something to do with the null PCI address that the card was getting.

So i have got several more DAC960's from a friend to try, 5 in total, so
i'm hoping i can get one of them to work, however now i'm getting the
following error when i try to insmod the module, this happens on a 3.5
or a 2.73 firmware controller:


DAC960: ***** DAC960 RAID Driver Version 2.2.11 of 11 October 2001 *****
DAC960: Copyright 1998-2001 by Leonard N. Zubkoff <l...@dandelion.com>
DAC960#0: Unknown Initialization Error FB for Controller at
DAC960#0: PCI Bus 0 Device 8 Function 0 I/O Address 0xA000 PCI Address
0x9002000

I have searched around pretty throughly and found 1 other instance of
this error but no fixes or ideas on what caused it...

Any ideas?

I suppose that if i can't get this to work i will have to try and get a
differnent brand of controller, I can get an AMI 466 (i think it is)
Raid controller, anyone had any experience with these under Alpha?

Thanks in advance


Campbell

I don't know about DAC960's, unfortunately, but I do know the AMI
"megaraid" line pretty well (too well, unfortunately). Right now and
probably forever, AMI megaraid-family controllers are unsupported on
Alpha-Linux. I ported the driver when I worked at API, but AMI was
unwilling to release some info that is vital to the card's initialisation
to me (even under NDA). So the driver will see the card, but the card
can't initialise itself into a known state and therefore doesn't work.

The funniest part of the whole thing is that they kept my changes in the
driver that they release, but didn't want to reciprocate by giving me
the last "piece of the puzzle" nor did they really even want to supply
any details on the newer cards (I was trying to get one of their U2W
cards working)...

I tried very hard to change their minds, but in the end it proved a waste
of time, unfortunately.

About the 'only' working RAID driver available at this time
are ICP-VORTEX (GDTH in the kernel). Expensive but very fast.
