Re: CACHE MEMORY alert from BMC

Shalom,

I think the error message is not referring to system memory which you have checked and found to be okay.

cache may refer to CPU cache, which is a little area of very fast memory designed to speed up CPU operations.

Use cstm,mstm or xstm to test the CPU's. Contact hardware support and see if the message is important or I am wrong.

Re: CACHE MEMORY alert from BMC

I'm not sure from where you get this message, but in case of a cache error there should be a log entry in MP system logs.

Check this.

Hope this helps!

Torsten.

Re: CACHE MEMORY alert from BMC

Perhaps you should ask your BMC support to explain, exactly, what this alert means - and how (what procedure is used) it is detected.

Re: CACHE MEMORY alert from BMC

BMC is the baseboard management controller - its a part of server hardware.

For exactly this reason the MP should log related events.

Hope this helps!

>Torsten: BMC is the baseboard management controller

Are you sure this message is from that BMC?
google finds "create_new_parameter: MEMRCache" hiding away in some bmc.com page.
The two hits on hp.com refer to bmc.com too.

Re: CACHE MEMORY alert from BMC

A google search turned up this:

MEMRCache: Displays the percentage of read misses in the buffer cache.

Found in this doc here:

http://www.scribd.com/doc/24178426/Bmc-Patrol-Unix

So this is nothing to do with physical memory - it's related to the number of hits in the file system buffer cache for reads. This sounds like one of those arbitrary settings that BMC Patrol has - I would look at the thresholds you have set and adjust them appropriately.
