In response to the HP Netserver LXe Pro lockup issue I had before,
and with the responses I've gotten so far, here is my current
plan of attack. Any further input or suggestions are as always
welcome:
1. I'm compiling without SMP support as we speak. The most this
thing has made it is 3 full days without locking up solid,
so if it runs for a week I'll blame it on 2.2.11 SMP, I guess.
NOTE: I can't go newer then 2.2.11 at this time due to the fact
the latest released raid0145 patch is for 2.2.11. RAID
people, I haven't tried it yet: Will it patch 2.2.12 without
too much hassle?
2. If still getting lockups without SMP, I'm going to try pulling
the Intel EEPro and let a 3c905B have a whack at it.
3. I just thought of this, but the 78xx firmware is probably still
the original from when the machine was purchased in 1996. I
guess I could broach the firmware-update route. I feel stupid
for not having done this yet.
4. If still no luck, I could possibly wheel a different SCSI
controller out there. Admittedly, I've never used anything but
IDE or 2940UWs in Linux boxes; what other cards are fairly well-
supported and reliable? I'll try disabling onboard and going
with a different controller if we get all the way down here to
the fourth point. [grin]
Thank you for all who have assisted so far, and in the future.

:
: I must say I've never seen this in my entire life, so
: I wanted to get some input. This is sent to both the
: linux-admin and linux-raid lists.
:
: I have a customer/friend (yes, the two-in-one combo that
: is often noted for being dangerous =) who recently upgraded
: an old SCO setup they had to SCO Openserver 5.0.5. This
: included selling him new hardware and the works. This meant
: that his old HP Netserver LXe Pro (which is a gorgeous machine)
: became a spare server for us to utilize.
:
: Being the avid Linux geek I am, I immediately dumped Linux
: on there. The Mylex DAC960 was not supported (the card
: is the old 2.x firmware variety, and HP wanted money to upgrade
: us to the 3.x series) so I could not utilize the hardware
: RAID. Instead, I went with software.
:
: It is a dual-processored machine (capable of 4, only utilizing
: two PPro 200's at this time, 512k cache each), so I have
: SMP compiled it. So at the current time, it basically is:
: linux-2.2.11-SMP with raid0145-990824 with four 2gb drives
: in a RAID-5. The SCSI bus is onboard Adaptec 78xx. The
: network card is an Intel Etherexpress PRO.
:
: The problem? It locks up. Solid. I've never in my life
: seen a Linux box just lock up, with no hints anywhere in
: logfiles. On the other hand, I've never gotten my hands on
: hardware this "big" (This sucker was $31k retail when they
: bought it). The machine is currently virutally unused (other
: then qpopper for POP mail); SAMBA is setup on it, but is
: currently completely unutilized at this time.
:
: It seems to lock hard every few days. Maybe 3 or 4? I see
: no coorelation of activity (ie, users doing something) and
: lockups, but am willing to dig a little deeper if someone has
: an idea.
:
: I was wondering two things:
: A. Are there any known incompatibilities with any of this
: hardware? I've seen some mentions of aix78xx, SMP, and
: raid causing problem. Is this what I'm bumping in to?
: B. Is there anything I can do to figure out WHAT is causing
: the hard lockups? Again, no hints in /var/log/messages or
: anywhere else. Possibly a serial cable to a dumb terminal
: constantly dumping system information?
:
: Any information or clues would be more then appreciated. Replies
: directly to the list are more then fine; I subscribe to both.
:
: Thanks.
