itanium rx2620 error mca

[Homsan]

We are getting error logs (from dmesg) in a few of our itanium rx2620. I
would like to know if the error is a 2-bit ECC error or 1-bit and which is
the faulty DIMM. I did look at various manuals of intel and i believe it is
a 1-bit error but I am not certian. And I do not know how to decifer the
card and module etc to find which is the faulty DIMM so as to replace it.

Thanks very much in advance! Stelios

Here is the error log:

The command was for hp-ux, but you can try this from efi:

> pdt
> info mem
> info warning

Within running OS environment, you can run "salinfo" to decode the SAL information. If this utility is not installed, you can download it from RedHat website.

In the offline mode, you can use IPF ODE CD ,E-diag tool "memdiag.efi"
From EFI shell prompt shell> errdump cpe
