Description
This document describes the memory mapping for Sun Fire[TM] T1000/T2000 and helps to identify the physical memory modules (DIMMs) installed and configured in the system.


Steps to Follow
The 'prtdiag -v' command on T1000 and T2000 reports only the total memory size in the system and does no longer provide information about the physical memory that is installed and configured. You can get the information for the configured memory from the output of the ALOM command 'showcomponent' in the following format:

MB/CMP0/<channel#>/<rank#>/<dimm#>

Example for Sun Fire T2000 with 16x DIMMs installed:
MB/CMP0/CH0/R0/D0
MB/CMP0/CH0/R0/D1
MB/CMP0/CH0/R1/D0
MB/CMP0/CH0/R1/D1
MB/CMP0/CH1/R0/D0
MB/CMP0/CH1/R0/D1
MB/CMP0/CH1/R1/D0
MB/CMP0/CH1/R1/D1
MB/CMP0/CH2/R0/D0
MB/CMP0/CH2/R0/D1
MB/CMP0/CH2/R1/D0
MB/CMP0/CH2/R1/D1
MB/CMP0/CH3/R0/D0
MB/CMP0/CH3/R0/D1
MB/CMP0/CH3/R1/D0
MB/CMP0/CH3/R1/D1

To collect the ALOM data ('showcomponent', etc.) for T1000/T2000 with explorer, you need to run explorer 5.2 (or later) with the Tx000 option (see troubleshooting doc 83612). Sun[TM] Explorer 5.5 and later will collect this data automatically.

Once you have the configured memory from 'showcomponent' ('showfru' will also output information regarding the installed memory), you can reference the T1000/T2000 memory layout, to map DIMM names that are displayed to DIMM socket numbers (Jxxxx) that identify the location of the DIMM on the motherboard. Attached are the memory layout maps for T1000 and T2000:

Comment: Hi NIta,
As requested, I replaced the attachments (images) with the links you provided for the customer to access the external memory pages:

https://support.oracle.com/handbook_private/Devices/Memory/MEM_SunFireT2000.html

The links (images) that are internal to Sun are moved to the Internal section. We need them for internal use, as this document was initially not part of the Normalization project.

Let me know if the updated links work on the external sunsolve.

Thanks,
Dencho

Comment: Hi T1000/T2000 Normalization team:

A customer pointed out a problem with some attachments in doc ID 87942 that
slipped right by us. Let me explain. It slipped by because inside SWAN they
work, even on external sunsolve within SWAN. But if a customer outside SWAN tries to
connect to these files, they cannot see them. Here is the customer feedback about
the attachments. I tested it outside SWAN and the customer is correct.

Subject: General Link Problem
Comments: Broken links to key images in this page:
http://sunsolve.sun.com/search/document.do?assetkey=1-9-87942-1

Links are as follows, and appear to be internal to Sun:
https://support.oracle.com/handbook_private/Devices/Memory/images/MEM_SunFireT2000.02.gif

https://support.oracle.com/handbook_private/Devices/Memory/images/MEM_SunFireT2000.03.gif

--------------------------------------
I think what you can do is remove the attachments and instead, link the customers to these external memory pages as follows:

https://support.oracle.com/handbook_private/Devices/Memory/MEM_SunFireT2000.html

https://support.oracle.com/handbook_private/Devices/Memory/MEM_SunFireT2000.html

I had to unpublish the doc temporarily. I'm moving it over to Dencho's
queue now..hope that's the right person to move it to. If not, let me
know and I can transfer it to someone elses queue. Once you look it over
and add the links instead of the attachments or, maybe decide upon something
different? You can submit the corrected doc back to me.

Thanks,
-nita
