scanning for bad ram

[Nick_Parrott at Dell.com]

Hi Paul,

There are no diags within OMSA, you need to boot off some diagnostics
media and run the MPmemory diagnostic. 

Clear the ESM/SEL log first, then run the test to see if anything fails,
if it does, you need to pop the lid and swap the faulty DIMM with a good
DIMM, clear the log again, run the diagnostic and confirm that the fault
follows the DIMM or the slot, then call support to get parts replaced if
under warranty.

MPmemory shows the SEL events, so clearing the log is a good idea as to
avoid confusion..

Regards,

Nick

Nick, thanks for the information. 

The reason I'm asking is because we have 3 1900's bought refurbished and
one
application is exiting with status 11 (SIGSEGV) on two of the servers.
The
provider of the software tells me it's probably due to hardware or ram
failure.

Can run osma and test the ram hardware while the server is up, will it
affect data stored in memory. I can always take one of the servers I'm
testing offline if it does.

It will indeed, both Single Bit errors and Multi Bit errors

Single bit's are ECC recoverable - so you won't see effect on
applications,
multi-bit you'll probably know about..

Any fault that the BMC (Baseboard Management Controller) logs will be
displayed in OMSA under "Logs" > "BMC/SEL"

Use Dell MPmemory to test DIMMs offline, it's on the 32-bit Diagnostics
CD's. It's a modified memtest86, however memtest86 will fail immediately
as
the system BIOS reserves a very small portion of memory space upon boot

I have yet to install osma on my 1950's I know it will monitor disks but
will it monitor and report problems with ram.
