SUN M8000主機 IOU板卡硬件更換

一、故障現象

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)

通過showstatus命令可以看到IOU#0已為降級狀態，IOU上裝有硬盤、HBA卡以及網卡等備件，IOU#0為降級狀態則運行不穩定，存在再次異常宕機隱患，一旦發生故障會影響操作系統正常運行，需要及時更換IOU#0模塊。

2.故障部件示意圖

IOU#0在M8000服務器上的安裝位置如下圖(紅色方框中的部件)：

二、實施過程

1.確定故障件Domain

當前M8000服務器Domain劃分如下表：DomainCMUIOU備注

0CMU#0、CMU#1IOU#0

1CMU#2、CMU#3IOU#2

從Domain劃分可見，發生故障的CMU#1和IOU#0都屬于Domain 0。

2.確定版本

XSCF>? version -c xcp

XSCF#0 (Active )

XCP0 (Current): 1121

XCP1 (Reserve): 1121

XSCF#1 (Standby)

XCP0 (Current): 1121

XCP1 (Reserve): 1121
