一、工具安装

cd /tmp;unzip 8-07-06_MegaCLI.zip
cd /tmp/Linux;rpm -ivh MegaCli-8.07.06-1.noarch.rpm
ln -s /opt/MegaRAID/MegaCli/MegaCli64 /bin/MegaCli64;ln -s /opt/MegaRAID/MegaCli/MegaCli64 /sbin/MegaCli64

查看阵列级别

/opt/MegaRAID/MegaCli/MegaCli64

二、工具使用

1、导出日志

sudo /opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL >/tmp/mega_`date +"%Y%m%d"`.log
cat /tmp/mega_`date +"%Y%m%d"`.log |grep -i 'Media Error Count|Slot Number'|awk '{tmp=$0;getline;print tmp"\t"$0}' >> /tmp/mega.format
cat /tmp/mega_`date +"%Y%m%d"`.log |grep -i 'Other Error Count|Slot Number'|awk '{tmp=$0;getline;print tmp"\t"$0}' >> /tmp/mega.format

2、查error count（media报错影响较大重点关注）

cat /tmp/mega.format|grep -v 'Error Count: 0'|sort -u|sort -n -k7|tail -3

3、查磁盘状态（Spun Up属于正常，其他状态需要核查）

cat /tmp/mega_date +"%Y%m%d".log|grep 'Slot Number|Firmware state'|awk '{tmp=$0;getline;print tmp"\t"$0}'

三、rebuild进度（65为Enclosure Device ID、18为Slot number）

1、先排查哪个磁盘在rebuild和 Enclosure Device ID、和磁盘id

sudo /opt/MegaRAID/MegaCli/MegaCli64  -PDList -aAll -NoLog|egrep 'Enclosure Device ID|Slot Number|Firmware state'

2、查看Rebuild进度

sudo /opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ShowProg -PhysDrv[65:18] -aALL

四、热备盘操作

/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP -Set [-EnclAffinity] [-nonRevertible] -PhysDrv[32:7] -a0

指定第1张阵列卡的第8块盘作为全局热备（默认从0开始计数）
为指定第1张阵列卡的第5块盘作为局部阵列（raid5)的热备

/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP -Set [-Dedicated [-Array1]] [-EnclAffinity] [-nonRevertible] -PhysDrv[64:4] -a0
