1 使用centos 6.
2 等linux系统live cd引导设备。并安装LSI megacli命令包。
2 使用MegaCli 来取得RAID 卡下硬盘的信息:
然后使用下面的命令:
1 /opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL
这样可以查出RAID 卡下面的内容.会显示如下:

Media Error Count: 0
Other Error Count: 1
Predictive Failure Count: 0
Last Predictive Failure Event Seq Number: 0
PD Type: SATA
Raw Size: 119.242 GB [0xee7c2b0 Sectors]
Non Coerced Size: 118.742 GB [0xed7c2b0 Sectors]

Firmware state: Online, Spun Up
SAS Address(0): 0x1e394d57aa996b80
Connected Port Number: 7(path0)
Inquiry Data: 0000000011070303A99EC300-CTFDDAC128MAG 0007 FDE Capable: Not Capable
FDE Enable: Disable
Secured: Unsecured
Locked: Unlocked
Needs EKM Attention: No
Foreign State: None
Device Speed: 6.0Gb/s
Link Speed: 1.5Gb/s
Media Type: Solid State Device
注意上面几个地方,上面会输出很多这样的信息,只有Media Type: Solid State Device .表示这是SSD .其中Device Id: 28 这个需要记下来.这个过一会使用smartctl 查询时会需要.我们可以见到上面都显示了硬盘的型号:Inquiry Data:
0000000011070303A99EC300-CTFDDAC128MAG .另外还有一个标志告诉你这个SSD 是不是正常的Firmware state: Online,Spun Up 这个选项,所以如果你做SSD 的监控报警,直接监控这个参数基本就行了.
接下来使用smartctl 来取得SSD 硬盘的详细信息
smartctl -a -d megaraid,28 /dev/sda1 -s on
这时,可能会显示如下的信息:
