Solution 1011116.1 : Sun Fire™ V490/480, V890/880: Associating 'asr-disable cpuX-bankX' to a Physical DIMM Location

Applies to:

Sun Fire V480 Server
Sun Fire V490 Server
Sun Fire V880 Server
Sun Fire V880z Visualization Server
Sun Fire V890 Server
All Platforms

Goal

This document is intended as a quick reference when using the ASR commands to manually enable or disable Memory banks on V480/V880, to associate the cpuX-bankX to physical dimm location. It is also aimed at the V490/V890, to associate the cmpX-bankX to physical dimm location.

Solution

The J-numbers listed notes the physical slot on the CPU/Memory board as reported by Solaris and are not required when issuing the asr-disable or asr-enable command.

Steps to Follow
Each physical bank of four DIMMs contains two logical banks. Solaris does not report which logical bank an error was sourced from. If you are trying to disable memory identified by Solaris you will need to disable both logical banks.

NB: The following are example commands for the V480/V890.
For V490/890 please use cmpX-bankX (eg: cmp0-bank0)

Comment: Hello
Made some small updates including enabling STM and moving the link to another Internal doc to the Internal section.
The other asr-disable docs are Internal Only, it would be useful for the customer to be able to see this doc to allow them to do troubleshooting themselves.
