二、下载、安装 MegCli

下载地址：wget

/2014/12/ibm_utl_sraidmr_megacli-8.00.48_linux_

#unzip ibm_utl_sraidmr_megacli-8.00.48_linux_

#cd linux

#rpm -ivh Lib_

#rpm -ivh

#故障硬盘修复（添加新硬盘或阵列）

#-PDMakeGood是改变状态由Unconfigured bad变成Unconfigured good

#-PhysDrv[252:2] 是硬盘信息[]内第一个数字是Enclosure Device ID，第二个数字是Slot Number

#-a0 是Adapter #0

1./opt/MegaRAID/MegaCli/MegaCli64 -PDMakeGood -PhysDrv[252:2] -a0

#硬盘变为Unconfigured good之后加入阵列

2./opt/MegaRAID/MegaCli/MegaCli64 -LDRecon -Start -r5 -Add

-PhysDrv[252:2] -L0 -a0

3.等待重建，大约需要2小时

Reconstruction : Completed 0%, Taken 1 min.

使用/opt/MegaRAID/MegaCli/MegaCli64命令会在当前目录生成日志文件可以加上 -NoLog参数取消日志

三使用命令及参数

3.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

4.查看磁盘缓存策略

5.设置磁盘缓存策略

缓存策略解释：

WT (Write through

WB (Write back)

NORA (No read ahead)

RA (Read ahead)

ADRA (Adaptive read ahead)

Cached

Direct

例子：

#/opt/MegaRAID/MegaCli/MegaCli64 -LDSetProp WT|WB|NORA|RA|ADRA -L0 -a0

#/opt/MegaRAID/MegaCli/MegaCli64 -LDSetProp -Cached|-Direct -L0 -a0

enable / disable disk cache

#/opt/MegaRAID/MegaCli/MegaCli64 -LDSetProp -EnDskCache|-DisDskCache

-L0 -a0

6.创建一个 raid5 阵列，由物理盘 2,3,4 构成，该阵列的热备盘是物理盘 5

#/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct

-Hsp[1:5] -a0

7.创建阵列，不指定热备

#/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct

-a0

8.删除阵列

#/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdDel -L1 -a0

9.在线添加磁盘

#/opt/MegaRAID/MegaCli/MegaCli64 -LDRecon -Start -r5 -Add -PhysDrv[1:4]

-L1 -a0

10.阵列创建完后，会有一个初始化同步块的过程，可以看看其进度。

#/opt/MegaRAID/MegaCli/MegaCli64 -LDInit -ShowProg -LALL -aALL

或者以动态可视化文字界面显示

#/opt/MegaRAID/MegaCli/MegaCli64 -LDInit -ProgDsply -LALL -aALL

11.查看阵列后台初始化进度

#/opt/MegaRAID/MegaCli/MegaCli64 -LDBI -ShowProg -LALL -aALL

或者以动态可视化文字界面显示

#/opt/MegaRAID/MegaCli/MegaCli64 -LDBI -ProgDsply -LALL -aALL

12.指定第 5 块盘作为全局热备

#/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP -Set [-EnclAffinity]

[-nonRevertible] -PhysDrv[1:5] -a0

13.指定为某个阵列的专用热备

#/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP -Set [-Dedicated [-Array1]]

[-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0

14.删除全局热备

#/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP -Rmv -PhysDrv[1:5] -a0

15.将某块物理盘下线/上线

#/opt/MegaRAID/MegaCli/MegaCli64 -PDOffline -PhysDrv [1:4] -a0

#/opt/MegaRAID/MegaCli/MegaCli64 -PDOnline -PhysDrv [1:4] -a0

16.查看物理磁盘重建进度

#/opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ShowProg -PhysDrv [1:5] -a0

或者以动态可视化文字界面显示

#/opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ProgDsply -PhysDrv [1:5] -a0

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

1、查看RAID级别

2、查看RAID卡信息，主要输出RAID卡的一些配置信息

RAID Level : Primary-1, Secondary-0, RAID Level Qualifier-0

Size : 1.086 TB

State : Optimal

Strip Size : 128 KB

Number Of Drives per span:4 //表示每4个物理盘做成一个RAID1盘组

Span Depth : 2 //表示共2个RAID1盘组做成了RAID10

3、查看所有硬盘的信息

/opt/MegaCli64 -pdlist –aALL

4、查看当前raid缓存状态，raid缓存状态设置为wb的话要注意电池放电事宜，设置电池放电模式为自动学习模式

/opt/MegaRAID/MegaCli/MegaCli64 -ldgetprop -dskcache

-lall -aall

5、 raid 电池设置相关

MegaCli -LDSetProp { WT | WB|NORA |RA | ADRA|-Cached|Direct} |

{-RW|RO|Blocked} |

{-Name[string]} |

{-EnDskCache|DisDskCache} –Lx |

-L0,1,2|-Lall -aN|-a0,1,2|-aALL

MegaCli -LDSetProp WT -L0 -a0

Physical Drive |Online|Failed –> Unconfigured|Rebuild|Online

6、通过脚本检测RAID 磁盘状态

#!/bin/bash

#check raid disk status

MEGACLI="/opt/MegaRAID/MegaCli/MegaCli64 "

$MEGACLI -pdlist -aALL | grep "Firmware state" | awk -F : '{print $2}'

| awk -F , '{print $1}' >/tmp/

$MEGACLI -pdlist -aALL | grep -E "Media Error|Other Error" | awk -F :

'{print $2}' >/tmp/

for i in `cat < /tmp/`;do

if [ $i -ne 0 ];then

curl

"/&state=ALARM&description=raid_disk_error"

done

for i in `cat < /tmp/`;do

if [ $i != Online ];then

curl

"/$state=ALARM&description=raid_disk_offline"

done

7、批处理脚本

Windows下脚本用的工具是gnu for windows平台的一些软件，如 bash grep awk cat 通过bash直接调用脚本

G:raid_checkunixtools> G:

#check raid disk status

MEGACLI="//G/raid_check/"

GREP="//G/raid_check/unixtools/"

AWK="//G/raid_check/unixtools/"

CAT="//G/raid_check/unixtools/"

CURL="//G/raid_check/unixtools/"

$MEGACLI -pdlist -aALL | $GREP "Firmware state" |$AWK -F: '{print $2}'

|$AWK -F , '{print $1}' >//c/

$MEGACLI -pdlist -aALL | $GREP -E "Media Error|Other Error" | $AWK -F :

'{print $2}' > //c/

for i in `cat < /tmp/`;do

if [ $i -ne 0 ];then

curl

"/&state=ALARM&description=raid_disk_error"

done

for i in `cat < /tmp/`;do

if [ $i != Online ];then

curl

"/$state=ALARM&description=raid_disk_offline"

done
