“五分钟学命令系列”之三十四《MegaCli命令》

这边要介绍一个很强大的软件MegaCli，是一款管理维护硬件RAID软件,可以查看当前RAID卡的所有信息。本文以系统盘两块做RAID1，其他三块数据盘做RAID0为例。

1、查询有几块物理磁盘

结果为数字几就是有几块物理磁盘

$ /opt/MegaRAID/MegaCli/MegaCli64 -PDGetNum -aALL | egrep "Physical Drives" | awk -F " " '{print $8}' 

3

2、查询RAID

结果为数字几就是有做了RAID几，下面命令的结果可以看出有两块盘做了RAID1，其他的是RAID0

$ /opt/MegaRAID/MegaCli/MegaCli64 -LdPdInfo  -aALL | egrep "RAID Level" | awk -F " " '{print $4}' 

Primary-1,

Primary-0,

3、查询驱动器位置，结果为磁盘组ID

$ /opt/MegaRAID/MegaCli/MegaCli64 -LdPdInfo  -aALL | egrep "Drive's position" | awk -F " " '{print $4}'

0

1

4、查询插槽ID

$ /opt/MegaRAID/MegaCli/MegaCli64 -LdPdInfo  -aALL | egrep "Slot Number" | awk -F " " '{print $3}'

0

5、查询设备ID

$ /opt/MegaRAID/MegaCli/MegaCli64 -LdPdInfo  -aALL | egrep "Device Id" | awk -F " " '{print $3}'

6、查询硬盘状态

$ /opt/MegaRAID/MegaCli/MegaCli64 -LdPdInfo  -aALL | egrep "Firmware state" | awk -F ":" '{print $2}'

7、查询磁盘大小

$ /opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL | egrep "Raw Size" | awk -F " " '{print $3}' | awk -F "." '{print $1}'

8、查询磁盘温度

$ /opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL | egrep "Drive Temperature" | awk -F ":" '{print $2}'

27C (80.60 F)

28C (82.40 F)

28C (82.40 F)

9、查询磁盘速度

$ /opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL | egrep "Device Speed" | awk -F " " '{print $3}'

6.0Gb/s

6.0Gb/s

3.0Gb/s

10、查询磁盘编码

每一个字母表示4位的二进制，因此是64位

$ /opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL | egrep "Inquiry Data" | awk -F ":" '{print $2}'

11、查询磁盘唯一标识

$ /opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL | egrep "WWN" | awk -F " " '{print $2}'

12、查看Rebuild进度

两种显示方式

$ /opt/MegaRAID/MegaCli/MegaCli64 -pdrbld -progdsply -physdrv[252:1] -aALL

$ /opt/MegaRAID/MegaCli/MegaCli64 -pdrbld -showprog -physdrv[252:1] -aALL

physdrv后面跟的是Enclosure Device ID和Slot Number
