小机主板微码升级过程

1、本人亲历的升级微码详细过程（一头汗啊）先介绍一下背景信息： 客户是西安市内的一家大型连锁商场，有一台Power550小型机，出现报错。 IBM POWER6 550 型号：8204-E8A；序列号：XXXXXXX 设备情况：2C，3.5GHz Power550,4G内存，146x4硬盘；AIX版本：6100-03-01-0921； 微码版本号:EL340_075； 用途：POS机数据备份。分析过程： 1、 机器前面板显示报错B181F126，当前的FW是340-075。从错误日志上看是一个未知的系统平台错误。 2、联系IBM工程师被告知可能是微码问题或机器主板问题，建议先升级系统微码，然后观察

2、，如果继续报错就的更换主板了。 3、经过IBM工程师确认，“建议您升级机器的fw到340的最新版即可解决，该错误属于fw误报，不会对机器运行产生任何影响。”操作过程 我先去IBM网站下载合适的微码版本(/support.fixcentral/) 发现有2个版本：Power6 System Firmware EL340_122、Power6 System Firmware EL340_132，都下载下来，计划安装132版本。经过和客户交流，发现前面板无HMC的连接，在服务器上没有保留与HMC连接的记录信息，OK，升级变简单了。一、首先查看目前微码的版本A
