如下Centos的安装

1、先安装Lib_Utils-1.00-09.noarch.rpm,接着安装MegaCli-8.02.21-1.noarch.rpm

rpm -ivh Lib_Utils-1.00-09.noarch.rpm
rpm -ivh MegaCli-8.02.21-1.noarch.rpm

2、安装完成后,产生以下文件夹,有日志信息和可执行命令

/opt/MegaRAID/MegaCli

64位主机产生的可执行文件是:

MegaCli64

3、建立链接,以更方便使用:

ln -s /opt/MegaRAID/MegaCli/MegaCli64 /usr/local/bin/megacli

这样就可以直接执行命令megacli了。

动态加载磁盘(磁盘损坏的更换操作)

查看有几个raid卡,一般都一个

[root@monitor ~]# megacli -PDList -aALL|grep Adapter
Adapter #0
[root@monitor ~]# 
因为只有一个卡,所有执行时参数加 -a0

更换盘后查看带有Unconfigured的盘信息
megacli -PDList -a0|grep Firm
megacli -PDList -a0|grep -B 16 Unconfig

记录Ecclosure Device ID和Slot Number

检查并清除异常状态:

megacli -CfgForeign -Scan -a0
megacli -CfgForeign -Clear -a0
 
清除坏盘的缓存,因为需要将新盘做raid0才能在fdisk可见(Dell/LSILogic PERC 6/ir可直接检测到硬盘,Dell/LSILogic PERC 6/i不能)


megacli -DiscardPreservedCache -l5 -a0 
megacli -cfgldadd -r0 [32:5] WB RA Direct -a0
 
注意上面第一个参数l5,其实就是系统中识别的sdf,就是清除slot number是5的那块盘的缓存。

第二行的参数32:5,就是指定Ecclosure Device ID是32,slot number是5的那块盘(sdf或者面板数字为5的盘)来做raid0

之后格式化和分区操作。

常用查看命令:

megacli -LDInfo -Lall -aALL 查raid级别

megacli -AdpAllInfo -aALL 查raid卡信息

megacli -PDList -aALL 查看硬盘信息

megacli -AdpBbuCmd -aAll 查看电池信息

megacli -FwTermLog -Dsply -aALL 查看raid卡日志

megacli -adpCount 显示适配器个数

megacli -AdpGetTime –aALL 显示适配器时间

megacli -AdpAllInfo -aAll 显示所有适配器信息

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

megacli -PDList -aAll 显示所有的物理信息

megacli -AdpBbuCmd -GetBbuStatus -aALL |grep ‘Charger Status’ 查看充电状态

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

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

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

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

megacli -cfgdsply -aALL 显示Raid卡型号,Raid设置,Disk相关信息
