下载至windows本地桌面,然后在linux命令行用命令:rz -be ,在弹出的窗口中选择刚才下载的压缩包(注意不要勾选已ASCII码方式传送文件)

tar xf megacli-8.02.21-1-mdv2012.0.x86_64.rpm.tar
rpm -ivh megacli-8.02.21-1-mdv2012.0.x86_64.rpm

 

yum install megacli -y 
查看Raid卡信息
megacli -LDInfo -Lall -aALL
查看硬盘信息:
megacli -PDList -aALL

 

备注:

RAID型号对应表信息如下:

RAID Level        : Primary-1, Secondary-0, RAID Level Qualifier-0"         #代表Raid 1

RAID Level        : Primary-0, Secondary-0, RAID Level Qualifier-0"         #代表Raid 0

RAID Level        : Primary-5, Secondary-0, RAID Level Qualifier-3"         #代表Raid 5

RAID Level        : Primary-1, Secondary-3, RAID Level Qualifier-0"         #代表Raid10

 

一、查看Raid卡信息
megacli -LDInfo -Lall -aALL 

[root@ robin]# megacli -LDInfo -Lall -aALL

二、查看硬盘信息:
[root@ robin]# megacli -PDList -aALL

raid卡的数据在硬盘上有一份,在raid卡中有一份,当逻辑有错误的时候,可以重新从硬盘把逻辑数据导入,这个时候会做一些检验和检查

raid卡的盘有4种基本状态。

Failed  基本无救,联系dell保修。

Online  正常装填。

Foreign   逻辑有错误,这个盘未识别,解决方法:从硬盘重新导入raid卡的逻辑数据。

Unconfigd 第一种情况就是这个盘没有配置在raid中,第二种情况就是逻辑有错误,这个盘未识别。解决方法:从硬盘重新导入raid卡的逻辑数据。第一种情况下,重新从硬盘导入逻辑数据也没办法,第二种情况下是可以的。

 

spans值 1,2,3,4做raid0,八块盘做raid1形成1、2、3、4

Drive's position: DiskGroup: 0, Span: 0, Arm: 1

如果盘坏在不同的raid1上,就可以,如果坏在相同的raid1上数据就完了,所以最大可以坏4块盘。

 

PD值 0、1、2、3、4、5、6、7、
