[parisc-linux] SCSI Disks on a K580 Help Required

[parisc-linux] SCSI Disks on a K580 Help Required

[Steve.Grady]

Hi,

I got my hands on a K580 Quad processors, 4G Ram, CD, DDS3 Tape drive,
2 Fibre Channels on HSC, Dual 100BaseT network connectors on HSC,
FW SCSI on HSC and 2 SCSI interface on HPPB (OK I know the HPPB is not
supported)
but no hard disks.

Previously I have installed PA-Linux on a 735/125.

I am trying to install palinux-2.4.18-pa59-ppc-20020728-netinstall image on
the K580
I am using a variety of SCSI disks I am trying to install to but I am having
problems.

The disks are being installed internally on the K580. I have downloaded the
users guide
from docs.hp.com.

First Try

I installed Tape and CD to Single ended bus of the Disk cage and install a
Maxtor Altas II
4.5G UW to ultra wide bus of Disk Cage and yes the cable was terminated.

The boot process found the CD, DDS3 but not the disk. I could boot from CD
but the installer 
complained about on disk.

Second Try

I installed Tape and CD to Single ended bus of the Disk cage and install a
Seagate
2.1G SE to SE bus of Disk Cage in parallel with the CD and Tape.

The boot process found the CD, DDS3 but not the disk. I could boot from CD
but the installer 
found the disk CD and Tape. I installed to disk and at reboot boot could not
find the disk
only the tape and the CD.

All other trys

I have tried various combinations but have not susceed in get the boot to
recognised the
hard disk. I cannot get Pa-linux to recognised the Ultra Wide bus which
leaves me to question
whether it is supported or do I have a hardware problem.

The Boot reports through its Search for Boot devices function that it finds

The 2 FC devices
the Lan (which I assume is the 10BaseT on the Core IO not the 100BaseT)
a sequential device (Tape Drive)
a random device (CD)

The primary boot device at present seems to me to be set up for the Fibre
Channel
(I think the I am not used to the addressing).

I have thought of Rboot or tftboot the K580 from the the 735 and then the
kernel will
recognise the disk. But this is not usefull in the long term as I may get
rid of the 735
and my Intel box which is my main server as I want to make the K580 my main
server.

Any help or suggestions would be appreciated,


Steve Grady

BTW Thanks for a great port my little 735 just sits there and works (mostly
running SETI)

Possible issues:

"First try." The internal disk drives in the K580 are fast wide 
differential. The differential is high voltage differential, not low 
voltage differential. Could be that the Maxtor 4.5GB UW is the wrong type.

"Second try." The normal cable in the K580 that goes to the tape and CD 
only has two open scsi connections plus the terminator. One connection 
for tape, another for the CD. Did you substitute another cable with a 
third open scsi connection?

Just guessing.

Well I hope I have not damaged the drive

Yes I substituted another cable (It did not come with any cables, they were
removed with the drive)
It was properly terminated by an external terminator. As I said after boot
from the CD a drive on the
single ended bus was detected ( and the CD and Tape) by the kernel but was
not detected by boot.

It has been suggested by someone else (they did not reply to list) that I
boot from CD which seems to me
the easiest work-around.

Thank for the assistance,

HP tested that. The NCR 53cxxx chips "tristate" the bus when
the wrong signaling is used. You can smoke devices by adding/removing
termination will the bus is active (ie disconnect a cable).

RE: [parisc-linux] SCSI Disks on a K580 Help Required

[Derek Engelhaupt]

I have the proper intenal cable for a K-Class in my spare parts case in
my van.  I think I have a couple of them in there for emergencies.  I
could spare one, but I guess you would have to be willing to pay for
shipping to the land of the Aussies.... ;)  Having worked on litterally
thousands of K-Class servers, I have never seen a drive smoke as a
result of the wrong termination or wrong type of bus.  I have however
seen it smoke the interface it was plugged into.  Usually it blows the
fuse on the board for the scsi bus.  Sometimes that fuse is replaceable
sometimes not.  The fuse for the K-Class internal disks is located on
the Core I/O board.  It's got a clear top/black bottom and just pulls
out of it's socket.  It has 2 legs that you should be carefull not to
break.  You can Ohm it with an Ohm meter to see if it's opened up or
not.  I would check with the Maxtor site and reference the model number
of the drive to find out whether or not it's LVD or HVD.  HVD is what
you need.  If the bus speed is 40MB/s than it's HVD.  If it's 80MB/s or
higher it's LVD and not useable unless you connect it to the single
ended bus.  HP does not support 3rd party boot disks as a general rule
and most drives will not boot HP-UX without HP firmware in them.  That
HP firmware is usually on Seagate or IBM disks.  HP has used Quantums
and others in it's workstations and even in that case it is a different
firmware level than in the servers.  Don't know if the drive not having
HP firmware could be an issue too.  If the fuse is blown I could drop
one of those in the box too.....have a bag of those laying around and
we don't replace fuses anymore.  Board swaps only even if it's just the
fuse that is blown.

Hehe.. my 715/64 does the same.. mind you it's also my web server too.
But mostly the only "real" work it does is seti. :)
