Possible Memory Issue on 8420

Possible Memory Issue on 8420

We recently had a memory problem with DIMM 1b on cell 0 which deconfigured. Today we replaced the DIMMS for 1b and 1a.

When we boot the system at BCH all of the memory is reported but when we look at CSTM cell 0 is reporting 1 dimms worth of memory less than it should.

We replaced the dimms a second time and still have the same issue.

Swapinfo also shows less total memory than what is in the system but dmesg shows the correct amount.

I believe BCH but I need to determine why CSTM and swapinfo show the incorrect amount especially CSTM since that is what our team monitors. I'm assuming the stm issue is cached data or a patch issue.

Below is the output showing memory. Any help is greatly appreciated.

>swapinfo also shows less total memory than what is in the system but dmesg shows the correct amount.

swapinfo(1m) only shows pseudo-swap, not memory size.
What HP-UX version are you using?

Re: Possible Memory Issue on 8420

make sure the extended memory tests are enabled at boot..

Re: Possible Memory Issue on 8420

How do I enable extended memory tests?

It would be several months before this system can be rebooted and extended tests ran.

Re: Possible Memory Issue on 8420

On boot the system according to syslog saw the correct amount of memory and looking at parstatus all of the memory is reported. I thought this might be an interleaving issue but there is only partion on this server. Looks like an stm problem to me.

Re: Possible Memory Issue on 8420

Paul,

I would tend to agree with you you that it looks like a Support tools bug.

your version is a few behind, so if you have the time it be worth while looking through the release notes for the later versions and see if anything crops up

http://docs.hp.com/en/diag/stm/stm_upd.htm

Also fi you have a quieter time on the system you could always run the exercise tool or the verify tool on the memory

see what that comes back with.

Andy

Re: Possible Memory Issue on 8420

Still working on getting a maintenance window. I'll post back what I find. Thanks for all the assistance
