使用MegaCli和Smartctl获取普通磁盘信息

[root@localhost ~]# cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 02 Id: 00 Lun: 00 Vendor: DELL Model: PERC H330 Mini Rev: 4.27 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi0 Channel: 02 Id: 01 Lun: 00 Vendor: DELL Model: PERC H330 Mini Rev: 4.27 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi10 Channel: 00 Id: 00 Lun: 00 Vendor: HL-DT-ST Model: DVD+-RW GU90N Rev: A3C0 Type: CD-ROM ANSI SCSI revision: 05

运行出错：

[root@localhost ~]# smartctl -i /dev/sda smartctl 5.43 2012-06-30 r3573 [x86_64-linux-2.6.32-642.el6.x86_64] (local build) Copyright (C) 2002-12 by Bruce Allen, 

Smartctl open device: /dev/sda failed: DELL or MegaRaid controller, please try adding '-d megaraid,N'

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

下载：

wget 

[root@localhost ~]# rpm -ivh MegaCli-8.00.46-1.i386.rpm 

error: Failed dependencies: Lib_Utils is needed by MegaCli-8.00.46-1.i386

解决：

[root@localhost ~]# wget  [root@localhost ~]# rpm -ivh Lib_Utils-1.00-08.noarch.rpm  Preparing... ########################################### [100%] Installing.... 1:Lib_Utils ########################################### [100%] [root@localhost ~]# rpm -ivh MegaCli-8.00.46-1.i386.rpm  Preparing... ########################################### [100%] 1:MegaCli ########################################### [100%] [root@localhost ~]# ls -al /opt/MegaRAID/MegaCli/MegaCli64 -rwxr-xr-x. 1 root root 2247688 Feb 3 2011 /opt/MegaRAID/MegaCli/MegaCli64

查看RAID级别：

[root@localhost ~]# /opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -Lall -aALL
