MegaCli是一款管理维护硬件RAID软件,可以通过它来了解当前raid卡的所有信息,包括
raid卡的型号,raid的阵列类型,raid
上各磁盘状态,等等。


通常,我们对硬盘当前的状态不太好确定,一般通过机房人员巡检来完成,有没有通过软件的方式来检查确定这个问题呢。


MegaCli就
可以做到,一般通过 MegaCli 的

下面使用smartctl透过Raid卡获取磁盘更详细的信息:

# smartctl manual 摘录..
              Under Linux , to look at SCSI/SAS disks behind LSI MegaRAID controllers, use syntax such as:
              smartctl -a -d megaraid,2 /dev/sda
              smartctl -a -d megaraid,0 /dev/sdb
             
where in the argument megaraid,N, the integer N is the physical disk
number within the MegaRAID controller.  This  interface  will
             
also work for Dell PERC controllers.  The following /dev/XXX entry must
exist:                 # 经测试只要存在即可,对应关系搞错确也仍可正常显示
              For PERC2/3/4 controllers: /dev/megadev0
              For PERC5/6 controllers: /dev/megaraid_sas_ioctl_node

[root@DB232 MegaCli]# smartctl -a -d megaraid,0 /dev/sda1
