Message-Id: <200110080912.LAA07746@noefs.ping.de> Date: Mon, 8 Oct 2001 11:12:09 +0200 (MEST) From: Wolfgang Wegner <wolfgang@noefs.ping.de> Subject: [suse-axp] [OT] AS600 5/333 HW question
Hi list,
sorry I am asking this quite off-topic question, but first I did not
find any better suited place to ask and second it seem to be somewhat
linux-related problems...
I have problems with the SCSI bus(es) of our old AS600 5/333 after
upgrading the old RedHat 5.0 to SuSE 7.1 I had to re-use the old
MILO, so maybe it has nothing to do with the software, but I am not
aware of what I might have changed in hardware...
The problem is that the machine hangs with messages like
Detected scsi disk sdg at scsi1, channel 0, id 2, lun 0
scsi1 channel 0 : resetting for second half of retries.
SCSI bus is being reset for host 1 channel 0.
while booting or - if it manages to boot about once every 20 tries -
after coming up. This did never happen before upgrading, it happens
when connecting only 2 devices (internal disk and CD) or 10 devices,
and it happens on both channels of the internal dual-wide-scsi-10mb-
ethernet-combo-card.
I already changed all cables and terminators, I normally know what I
am doing when installing SCSI devices (termination, IDs and so on), and
I really do not know what else I could look for. At the moment, the
machines *seems* to accept the "first" channel (channel 1 in the ARC
console), but does not like the second channel (channel 0 in the ARC
console, only external connection).
Is there any known incompatibility of this controller, or any known
issues (fuses, switches I could look for)? Or, at least, is there any
documentation available for this card?
Here's what "display hardware configuration" says:

And here comes MILO output:

...and there it sits forever.
As mentioned above, it is not necessarily a problem of the DGHS, just
at the moment the machine decided not to like this particular disk. Tomorrow
it might be another one... :(
Any help is appreciated! (Even if it is "throw out this crap card and
buy an el-cheapo NCR810" - I am not far away from doing so...)
Regards,
Wolfgang
