SUN M8000主机 IOU板卡硬件更换
一、故障现象
1.日志分析
XSCF> showstatus
*IOU#0 Status:Degraded;
XSCF> showlogs -v error
Date: May 24 20:44:22 CST 2019 Code: 80002000-33010000-0167058a00000000
Status: Alarm Occurred: May 24 20:44:20.367 CST 2019
FRU: /IOU#0
Msg: DDC configuration error. DDC wrongly installed(detector=5)
Date: May 25 19:09:03 CST 2019 Code: 80006000-33010000-0167058a00000000
Status: Alarm Occurred: May 25 19:08:38.909 CST 2019
FRU: /IOU#0
Msg: DDC configuratin error. DDC wrongly installed(detector=5)
通过showstatus命令可以看到IOU#0已为降级状态，IOU上装有硬盘、HBA卡以及网卡等备件，IOU#0为降级状态则运行不稳定，存在再次异常宕机隐患，一旦发生故障会影响操作系统正常运行，需要及时更换IOU#0模块。
2.故障部件示意图
IOU#0在M8000服务器上的安装位置如下图(红色方框中的部件)：
二、实施过程
1.确定故障件Domain
当前M8000服务器Domain划分如下表：DomainCMUIOU备注
0CMU#0、CMU#1IOU#0
1CMU#2、CMU#3IOU#2
从Domain划分可见，发生故障的CMU#1和IOU#0都属于Domain 0。
2.确定版本
XSCF> version -c xcp
XSCF#0 (Active )
XCP0 (Current): 1121
XCP1 (Reserve): 1121
XSCF#1 (Standby)
XCP0 (Current): 1121
XCP1 (Reserve): 1121
3.硬件更换
