Re: [Freeipmi-users] ipmimonitoring: correctable memory error vs. ipmitool: Memory 0 error

[Al Chu]

I totally forgot yesterday.  There is a working around called
"discretereading" in ipmi-sensors specifically for HP systems.  You can
specify it w/ the -W option.  I wrote a small blurb about it here.  

http://www.gnu.org/software/freeipmi/freeipmi-faq.html#Why-is-the-output-from-FreeIPMI-different-than-another-software_003f

Short answer, b/c of the kookiness in HP systems, both FreeIPMI and
ipmitool (by default) output the wrong thing.  I cannot speak to whether
there is a workaround for this in ipmitool.

As for your original question, I'm not sure how to clear the
"Correctable Memory Error".  It appears to be a bug in HP's firmware.
You'll notice that it reports "Correctable Memory Error" and "Presence
Detected".  The event bit notifying the correctable memory error appears
to be stuck (the bit for Presence Detected is uhh "good").  I suppose
it's possible a hard reset (bmc-device --hard-reset or a hard button
push) could clear it??

Sorry, wish there was better news.
