使用 MegaCLI 检测磁盘状态并更换磁盘 原

之前写了一篇文章介绍如何更换线上服务器磁盘操作流程,当时是把整体机器的磁盘全部不换掉了,但是最近另一台机器部分磁盘损坏,raid类型为10,经检测,只需要更换坏掉的磁盘即可,补充文档如下。

安装MegaCLI

安装包 下载地址

安装过程

# 首先下载获取安装包
# 解压
$ tar -zxf MegaCli8.07.10.tar.gz
$ cd MegaCli8.07.10/Linux/
$ rpm -ivh Lib_Utils-1.00-09.noarch.rpm MegaCli-8.02.21-1.noarch.rpm

# 加入系统环境
$ ln -s /opt/MegaRAID/MegaCli/MegaCli64 /usr/local/bin/MegaCli 
$ MegaCli -v                               
      MegaCLI SAS RAID Management Tool  Ver 8.02.21 Oct 21, 2011

# 安装完成!
  • 冲突处理: $ rpm -ivh Lib_Utils-1.00-09.noarch.rpm MegaCli-8.02.21-1.noarch.rpm 准备中... ################################# [100%] file /opt/lsi/3rdpartylibs/x86_64/libsysfs.so.2.0.2 from install of Lib_Utils-1.00-09.noarch conflicts with file from package srvadmin-storelib-sysfs-9.1.0-2757.12163.el7.x86_64
  • 原因: Lib_Utils和Dell服务器自带的包srvadmin冲突,直接将其卸载,然后安装即可。 rpm -e srvadmin-storelib-sysfs-9.1.0-2757.12163.el7.x86_64 --nodeps

使用指南

基本用法

# 查raid级别
$ megacli -LDInfo -Lall -aALL 

# 查raid卡信息
$ megacli -AdpAllInfo -aALL 

# 查看硬盘信息
$ megacli -PDList -aALL 

# 查看电池信息
$ megacli -AdpBbuCmd -aAll 

# 查看raid卡日志
$ megacli -FwTermLog -Dsply -aALL 

# 显示适配器个数
$ megacli -adpCount 

# 显示适配器时间
$ megacli -AdpGetTime –aALL 

# 显示所有适配器信息
$ megacli -AdpAllInfo -aAll     

# 显示所有逻辑磁盘组信息
$ megacli -LDInfo -LALL -aAll    

# 显示所有的物理信息
$ megacli -PDList -aAll     

# 查看充电状态
$ megacli -AdpBbuCmd -GetBbuStatus -aALL |grep 'Charger Status' 

# 显示BBU状态信息
$ megacli -AdpBbuCmd -GetBbuStatus -aALL 

# 显示BBU容量信息
$ megacli -AdpBbuCmd -GetBbuCapacityInfo -aALL 

# 显示BBU设计参数
$ megacli -AdpBbuCmd -GetBbuDesignInfo -aALL    

# 显示当前BBU属性
$ megacli -AdpBbuCmd -GetBbuProperties -aALL    

# 显示Raid卡型号,Raid设置,Disk相关信息
$ megacli -cfgdsply -aALL    
## 磁带状态的变化,从拔盘,到插盘的过程中。
Device           |Normal |Damage  |Rebuild |Normal
Virtual Drive    |Optimal|Degraded|Degraded|Optimal
Physical Drive   |Online |Failed Unconfigured|Rebuild|Online

# 查看物理磁盘状态:
$ megacli -PDRbld -ShowProg -PhysDrv  [Enclosure Device ID:Slot Number]  -a0
## Rebuild 中的物理磁盘状态中会显示:"Firmware state: Rebuild"

# 查询 Rebuild 进度:
$ megacli -pdrbld -showprog -physdrv[E:S] -aALL
## 返回内容类似于下面这样:
Rebuild Progress on Device at Enclosure 32, Slot 5 Completed 77% in 101 Minutes.

# 以文本进度条样式显示 Rebuild 进度:
$ megacli -pdrbld -progdsply -physdrv[E:S] -aALL
## 屏幕显示类似下面的内容:
Rebuild progress of physical drives...
Enclosure:Slot               Percent Complete                       Time Elps
      032 :05   #######################87 %################*******  01:59:07 
Press key to quit...

# 查看 RAID 卡 Rebuild 参数:
$ megacli -AdpAllinfo -aALL | grep -i rebuild
## 返回结果类似下面这样
Rebuild Rate                     : 30%
Auto Rebuild                     : Enabled
Rebuild Rate                     : YesForce 
Rebuild                    : Yes

# 设置 RAID 卡 Rebuild 比例为60%:
$ megacli -AdpSetProp { RebuildRate -60} -aALL
## 设置成功后返回:
Adapter 0: Set rebuild rate to 60% success.

由以上信息可知该服务器有6块磁盘(Device Id)。

卸载故障硬盘

$ MegaCli -PDOffline -PhysDrv[32:2] -a0
$ MegaCli -PDOffline -PhysDrv[32:0] -a0

上面命令中 322 以及 -a0 的对应关系:

Adapter #0
Enclosure Device ID: 32
Slot Number: 2

替换故障硬盘

此时故障硬盘已经OFFLINE,在服务器现场查看时,故障硬盘闪烁的是黄灯,正常硬盘的绿灯; 拔下故障硬盘,插上好硬盘,硬盘灯闪烁为绿色,并硬盘快速旋转,表示硬盘正在rebuild状态,查看状态如下:

$ MegaCli -PDList -aAll -NoLog
...
Enclosure Device ID: 32
Slot Number: 3
...
Firmware state: Rebuild
...

查看rebuild进度

$ MegaCli -PDRbld -ShowProg -PhysDrv[32:2] -aAll

Rebuild Progress on Device at Enclosure 32, Slot 3 Completed 16% in 94 Minutes.

磁盘更换完成

$ MegaCli -PDList -aAll -NoLog | grep 'Firmware state'
Firmware state: Online, Spun Up
Firmware state: Online, Spun Up
