smartmontools.x86_64 : Tools for monitoring SMART capable hard disks
[root@localhost scripts]# yum install smartmontools.x86_64 -y二、参数介绍:
smartctl
-i 指定设备
-d 指定设备类型,例如：ata, scsi, marvell, sat, 3ware,N
-a 或A 显示所有信息
-l 指定日志的类型，例如:TYPE: error, selftest, selective, directory,background, scttemp[sts,hist]
-H 查看硬盘健康状态
-t short 后台检测硬盘，消耗时间短
-t long 后台检测硬盘，消耗时间长
-C -t short 前台检测硬盘，消耗时间短
-C -t long 前台检测硬盘，消耗时间长
-X 中断后台检测硬盘
-l selftest 显示硬盘检测日志三、命令演示介绍：
运行 smartctl --scan 以打印附加设备id和RAID类型的所有设备：

[root@localhost scripts]# smartctl --scan
/dev/sda -d scsi # /dev/sda, SCSI device
/dev/sdb -d scsi # /dev/sdb, SCSI device
/dev/bus/0 -d megaraid,0 # /dev/bus/0 [megaraid_disk_00], SCSI device
/dev/bus/0 -d megaraid,1 # /dev/bus/0 [megaraid_disk_01], SCSI device
在这里，megaraid 是RAID类型，megaraid_disk_00第一个0代表的是raid0 第二个0代表的是硬盘设备 id 0
megaraid 是RAID类型，megaraid_disk_01第一个0代表的是raid1 第二个1代表的是硬盘设备 id 1
[root@localhost scripts]# smartctl -i /dev/sda1

由于演示的服务器是dell的，同时事先给这个机器的2块ssd硬盘做了raid0的
