linux查看RAID信息

linux查看RAID信息

发表于2013 年 12 月 22 日

RAID分为软RAID和硬RAID

软RAID查看

cat /proc/mdstat

硬RAID查看

在启动画面进raid卡查看

IM(RAID1)、IME(RAID1E)、IS(RAID0)

在系统中查看

# dmesg |grep -i raid

[ 6.346983] megaraid_sas 0000:03:00.0: PCI INT A -> GSI 33 (level, low) -> IRQ 33
[ 6.346992] megaraid_sas 0000:03:00.0: setting latency timer to 64
[ 6.470380] scsi0 : LSI SAS based MegaRAID driver
[ 25.827254] md: Autodetecting RAID arrays.

proc中的RAID信息

# cat /proc/scsi/scsi

查看RAID卡型号

# lspci | grep RAID
03:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 1078 (rev 04)

可以发现上面这台服务器的RAID卡是LSI的，服务器是DELL的，要查看更详尽的信息就需要针对RAID卡在系统里面装驱动了，如去LSI,或DELL网站可以找到对应的驱动。

搜到megaCLI可以试一下

通过DELL对应驱动查看

网上还有通用工具，如megasasctl，很久没有更新了，也可以试一下
