安装

Centos
wget https://docs.broadcom.com/docs-and-downloads/raid-controllers/raid-controllers-common-files/8-07-14_MegaCLI.zip
uzip 8-07-14_MegaCLI.zip
rpm -ivh MegaCli-8.07.14-1.noarch.rpm

Ubuntu

在线

修改 /etc/apt/sources.list 在末尾添加

deb http://hwraid.le-vert.net/ubuntu precise main

wget -O - http://hwraid.le-vert.net/debian/hwraid.le-vert.net.gpg.key | sudo apt-key add -

apt-get install megacli megactl megaraid-status

离线

wget http://hwraid.le-vert.net/debian/pool-stretch/megacli/megacli_8.07.14-2%2BDebian.stretch.9.9_amd64.deb

dpkg -i megacli_8.07.14-2+Debian.stretch.9.9_amd64.deb

apt-get install libncurses5 libtinfo5

apt --fix-broken install

查看

1.查看阵列卡信息
/opt/MegaRAID/MegaCli/MegaCli64 -AdpAllInfo -aALL

2.查看物理磁盘信息

/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL|egrep 

"Slot Number|PD Type|Raw Size|Firmware state|Media Type"|sed 's/Slot/\nSlot/g'

Adapter#0   -----raid卡控制器编号
Enclosure Device ID: 64  -----外壳设备ID，也就是raid卡的ID号
Slot Number: 6			------磁盘槽位号
PD Type: SAS			------磁盘类型
Raw Size: 3.638 TB [0x1d1c0beb0 Sectors]  	------大小
Firmware state: Online, Spun Up				------磁盘状态

3.查看RAID组信息：
/opt/MegaRAID/MegaCli/MegaCli64 -LdPdInfo -aALL|egrep \
"RAID Level|^Size|Slot Number|Virtual Drive"|sed 's/Virtual/\nVirtual/g'

4.查看物理磁盘个数

/opt/MegaRAID/MegaCli/MegaCli64 -PDGetNum -aALL

5.查看磁盘温度

/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL | egrep </span>

"Drive Temperature" | awk -F ":" '{print $2}'

6.扫描外来配置的个数：

/opt/MegaRAID/MegaCli/MegaCli64 -cfgforeign -scan -a0

/opt/MegaRAID/MegaCli/MegaCli64 -cfgforeign -preview -a0 查看当前的磁盘在normal时的位置

/opt/MegaRAID/MegaCli/MegaCli64 -cfgforeign -import -a0   来导入配置，恢复虚拟磁盘组

/opt/MegaRAID/MegaCli/MegaCli64 -cfgforeign -dsply -a0

7.删除外来配置

/opt/MegaRAID/MegaCli/MegaCli64 -cfgforeign -clear -a0

** 此命令慎用 **

MegaCli64 -cfgforeign -clear -a0 //这里的a0表示第一个raid卡控制器上的外来配置

8.查看磁盘错误

/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL|grep Error

Medai Error Count 表示磁盘可能错误，可能是磁盘有坏道，

这个值不为0值得注意，数值越大，危险系数越高

Other Error Count 表示磁盘可能存在松动，可能需要重新再插入

9.将某块物理盘下线/上线

/opt/MegaRAID/MegaCli/MegaCli64 -PDOffline -PhysDrv [32:4] -a0

/opt/MegaRAID/MegaCli/MegaCli64 -PDOnline -PhysDrv [32:4] -a0

10.查看raid陈列中掉线的硬盘：

/opt/MegaRAID/MegaCli/MegaCli64 -pdgetmissing -a0

11.查看，开启或关闭jbod模式（硬盘直通功能）

查看：MegaCli -AdpGetProp -enablejbod -aALL

打开：MegaCli -AdpSetProp -EnableJBOD -1 -aALL

关闭：MegaCli -AdpSetProp -EnableJBOD -0 -aALL

创建

1.用slot2号的盘创建raid0
/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r0[32:2] WB Direct -a0

2.用slot3,4号盘创建raid1

/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r1 [32:3,32:4] -a0

3.用slot5,6,7号盘创建raid5

/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r5 [32:5,32:6,32:7] -a0

4.用slot9,10,11,12号，创建一个raid10

/opt/MegaRAID/MegaCli/MegaCli64 -CfgSpanAdd -r10 -Array0[32:8,32:9] -Array1[32:10,32:11] -a0

5.如果创建报错

Exit Code: 0x26

/opt/MegaRAID/MegaCli/MegaCli64 -PDMakeGOOD -Physdrv [32:8] -force -aALL #将磁盘格式转换一下

删除

1.删除raid组0的raid组
/opt/MegaRAID/MegaCli/MegaCli64 -cfglddel  -L0 -a0

案例

/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL|egrep \
"Slot Number|PD Type|Raw Size|Firmware state|Media Type"|sed 's/Slot/\nSlot/g'

/opt/MegaRAID/MegaCli/MegaCli64 -LdPdInfo -aALL|egrep </span>

"Enclosure Device|RAID Level|^Size|Slot Number|Virtual Drive"|sed 's/Virtual/\nVirtual/g'

1.查看磁盘raid后的虚拟磁盘，和系统的盘符对应关系,根据对应关系，删除raid并重组raid

/opt/MegaRAID/perccli/perccli64 /c0/vall show

udevadm info -q path -n /dev/sdb

ll /dev/disk/by-path

##仅限DELL服务器

第一条命令结果中VD号，和第二条命令结果中block前的字符串中的第三位，

一一对应，确认系统盘符和raid盘的对应关系

2.确认并删除raid

确认要删除raid前，对应的物理盘槽位号

/opt/MegaRAID/MegaCli/MegaCli64 -LdPdInfo -aALL|egrep </span>

"RAID Level|^Size|Slot Number|Virtual Drive"|sed 's/Virtual/\nVirtual/g'

删除vd1,(L1)

/opt/MegaRAID/MegaCli/MegaCli64 -cfglddel  -L1 -a0

3.重组raid

/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r0[32:2] WB Direct -a0

4.格式化

mkfs.xfs

5.挂载

mount

blkid
