Re: Red Hat and Proliant lock up's
What runlevel do you run these servers at?
If these are real servers make sure you have
id:3:initdefault:
in /etc/inittab. This way you eliminate X alltogether.
Also make sure that you have the latest firmware and PSP.
Can you login through the iLO/RILO card when these lock-ups happen? Is there anything to indicate problems in the IML?
Regards,
Ross

Re: Red Hat and Proliant lock up's
They are being run at run level 3.
Not sure how to connect using the iLO/RILO card. No connection through network or kvm, and all logs stop at time hard lock appears to happen.
When talking to HP they had us install the insight manager agents. This changed the behaviour from lockups to rebooting. We were able to get some dumps, but they have now come back and said it is a software issue. No problem with the hardware.
We are now talking with Red Hat and have sent them a vmcore dump, and they have requested another dump to do some comparisons but we have not got another successful dump yet.
Do your servers run with the smp kernel. Have you tried to run them with the non-smp kernel? Have you tried disabling the hyper-threading?
Thanks.
Dan

Re: Red Hat and Proliant lock up's
Are all the machines that are locking up running Oracle ? What version ? App Server or Database ?
We've seen similar issues on a number of DL380 G3's all running RHEL 3, and Oracle Application Server 10g (9.0.4.0.0)
Every now and then the machines will just lock up - they'll normally drop off the network, but occasionally they'll stay on the network but they can't be logged into, either on the console or via SSH.
If I use iLO to look at the X console, I see the time at which the lock up happened, but there's no response from the keyboard or mouse.
Its very frustrating to say the least !
Cheers,
Rob

Re: Red Hat and Proliant lock up's
Some of them are running Oracle Database Server (8.1.7) but others only run Apache or Amavis/Spamassasin, some are connected to a MSA1000 SAN others just DAS, so for us there is no clear lead. When a hang-up occurs, the console is totaly black and there is no network connectivity (no ssh, sometimes a ping is possible).
Thanks and cheers,
Andre

Re: Red Hat and Proliant lock up's
The problem turned out to be the HP Insight Manager agents causing this. I disabled the agents and haven't had a lockup since.
I have an open case with HP for the past 3 months but the technician basically gave up trying to figure out the problem..
