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:

Domain

CMU

IOU

备注

0

CMU#0、CMU#1

IOU#0

1

CMU#2、CMU#3

IOU#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

XSCF> showstatus 

*   IOU#0 Status:Degraded;

XSCF> replacefru
