Re: ML370G3 Hanging Problem
Server has now been running for 24 hours.
I need to wait until it next hangs.

Re: ML370G3 Hanging Problem
However, in response to a support request, HP have suggested clearing the CMOS on thhe server:
"Let clear cmos on the server.
Clearing CMOS
Down the server to clear nvram.
Access the cover when the server is powered down. See the cover for the location of the maintenance switch. Switch #6 on the system maintenance switch from a default position of off to on.
Then apply power to the server.
When you see video, then turn the server off.
Place the switch # 6 back to the default position and apply power. Select F9 at post and then save to reconfigure with the correct controller order and exit. "
We have done this today and rebooted.
If this has nay impact, I'll update this thread.

Re: ML370G3 Hanging Problem
One of our ML370s hung last Monday having been up for 32 days.
We updated both servers with RedHat up2date, latest version of PSP and BIOS last Thursday.
They then both hung during the weekend.
We have now been advised to disable Hyperthreading on the processors, so this has been done and the machines rebooted.

Re: ML370G3 Hanging Problem
Yes our ML370s are running on Smart Array 641 Raid Controllers.
How do we tell which firmware version is running?
What version should we upgrade to and where can it be downloaded?+
Incidentally, our two ML530s installed at the same time, with the same versions of Red Hat Linux, PSP etc have Smart Array 6402 Raid Controllers and these two servers have never exhibited the 'hanging' problem.

I bet it's the firmware on your Smart Array 641 controller....
I recently experienced a problem with the SA641 controller on ML350 and ML370 servers that caused the system load to rise very rapidly (> 40), halting most network services. It appeared as though the controller would shutdown and that processes that depended upon Disk I/O would go into STAT D (uninterruptible sleep), forcing the load up by one unit per process. Programs loaded into memory (the kernel, top, etc.) were unaffected. This always occured after 3-7 days of uptime (usually when physical memory was cached and swapping occurred).
This problem was fixed by replacing the 641 with a 6400 or 5300 series controller... OR downgrading the firmware (to the last revision from 2003) on the 641. The new firmware on the 641 was just released last week, and seems to have corrected the issue.
I spoke with several HP techs, as I have about 100 systems around to country to support. They told me to simply stop selling that raid controller until they released a new firmware. Messy. All of my systems are RedHat 8.0, run the 6.40 hpasm and cmastor drivers and use 5300, 6400 or 64x series raid controllers with custom vanilla 2.4.21 or 2.4.26 kernels. I experienced this in a repeatable fashion on a new ML350, but a coworker had the same issues with RHEL 3.0 on a 641-equipped ML370 and the 7.0 agents.
The bad firmware is the March 2004 Smart Array 1.92A. The good ones seem to be 2.26B or 1.30.
http://h18000.www1.hp.com/support/files/server/us/download/21214.html
So in this case, try downloading the new firmware for the 640 and see if it stops the crashes. To test, you may want to leave a console running top open on the server and watch the load rise. Most services will stop responding after the load hits 40+.

Re: ML370G3 Hanging Problem
This is looking promising.
The Smart Array is currently running firmware 1.92.
I'll install 2.26B and see if it sorts it out.
Thanks for your help.
