[parisc-linux] soft power and power light on 712/60

[parisc-linux] soft power and power light on 712/60

[Derek Ellis]

Hello,

I have sort of a weird problem.  I installed Debian 3.0 on Sunday and it =
came up great on my 712/60.  The only problem is the soft-power switch do=
esn't work and the power light flashes while searching for the boot devic=
e and then goes off once it starts booting. =20

Output of uname -a:
Linux gecko 2.4.20-32 #1 Sat Mar 22 14:03:22 CET 2003 parisc unknown
and /proc/sys/kernel/soft-power =3D 1

The only thing unusual about the setup is that I replaced the old 500mb H=
P hard drive with a 4.5gig IBM drive with a 68pin-50pin converter.

Is the drive and converter causing the problem, or is there something I c=
an do software wise to fix this?

Thanks,
Derek Ellis

Hmm it is highly probable.

Four years ago, for a project of upgrade 712 workstation, we asked to HP
if it was possible to put internal (SE) 4Gb disk. HP said that it was only
supported on 712/100.

Later, I had the opportunity to test Linux on a old 4Gb (SE) external disk
with an old 712/60. (Even thought it was the very begining, it still works
fine and help me a lot). Then I remember that 'not supported' didn' t means
that it would not works. So I removed this disk from its enclosure and put
it into the workstation. Well it works but not for a long time: apparently
it warmed too much  but fortunately not too long time (so I can put it back
in its original enclosure and continu to work). So there are an actual problem
of heat exchange in this small box?

For above mentioned project, we also use external SE 4Gb disk with wide (68
pins) connector without pb. Is your 4.5Gb IBM disk is well of SE type?

I have had no heat problems.  The IBM drive is a 68-pin SE drive from '98=
.  It runs very cool and never gets too hot to touch.  I  put it internal=
ly since that was easier than finding an unused external enclosure.

Did the soft power & light work with the external enclosure?

Thanks,
Derek

Well, that is nice 4u.

I well understand.

Sorry, could not help you right now: my only linux boot disk (a Seagate)
is running a 64bits N (and it spend long time to reboot) and the rest are
only data disk used on hpux :(.

The very last stuff I foreseen that you could check is the symbios driver
compile into your kernel.
I personaly use the rev2 one (the only way I know to check this is by looking
into your kernel config file which stand normaly into your /boot dir).

hope this will help you anyway,
    Joel

The only reason I can imagine it should not work is addressing the
boot-image from the boot-prom.

Or else, it should not be called scsi...

When you look inside a 712, you should expect heat problems with the drive.
Its mounted in polysterene foam, also known for its perfect heat
insulation...

Hence, if you expect or experience heat problems in a 712, you can remove
the insulation and create real mounting brackets.


btw: all my ideas, not physically tested.

I don't know about the light, but a kernel upgrade might help the
switch.  Earlier kernels did not enable the power switch.  Not sure
which version made it work (although I thought the kernel on the Debian
3.0 CDs supported it.)  I haven't had a chance to run parisc linux for a
while, unfortunately, and the D270 I was using did nothing when the
power switch was switched, although the kernel I was running was
supposed to enable it, so maybe the kernel doesn't enable it for all
parisc machines?  (The switch did work in HPUX and I think it even
worked at some point in Linux and later stopped.)

Re: [parisc-linux] soft power and power light on 712/60

[Derek Ellis]

I wonder if the problem is with the precompiled 2.4.20-pa32 kernel, since=
=20that is what I am using.

Last night I also put my old 500MB HP drive back in and the light & power=
=20switch worked correctly with the 2.4.18 kernel.  I then used the netwo=
rk install CD (with kernel 2.4.20-pa32) to reinstall that drive.  After t=
he install the light & power didn't work, so this leads me to believe the=
re is something with that kernel.

You are mixing up marketing, implementation, and "supported".
HP decided the older box wasn't worth supporting.
I'l hazard a guess the "upgrade" would not generate enough revenue
to offset the additional qualification/inventory/support burden.

And SCSI implementations are not always compatible because they
don't implement all the same features. Delayed spinup and
Target-Initiated Syncronous Negotiation are two SCSI disk features
that early host controller firmware typically have trouble with.

I had a similar problem a while ago. The following URL should lead you to
the discussion I had that time:
http://lists.parisc-linux.org/hypermail/parisc-linux/8454.html
So eventually, the soft power worked, and is still working on my 712/60 even
with the latest kernel. Please note that I build the kernels myself, I never
use prebuilt ones (unless for installing ;) ). You should find my working
.config as an attachment
(http://lists.parisc-linux.org/hypermail/parisc-linux/att-8454/02-.config).
You can use this one, or do a diff with your .config to see what you're
missing.

Hope this helps.

Ahhh, thanks.  Now I just need to get one of the parisc boxen back from
the dark side ;)
