linux查看RAID信息
RAID分為軟RAID和硬RAID
軟RAID查看
cat /proc/mdstat
硬RAID查看
在啟動畫面進raid卡查看
IM(RAID1)、IME(RAID1E)、IS(RAID0)
在系統中查看
# 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 Attached devices: Host: scsi0 Channel: 00 Id: 32 Lun: 00 Vendor: DP Model: BACKPLANE Rev: 1.07 Type: Enclosure ANSI SCSI revision: 05 Host: scsi0 Channel: 02 Id: 00 Lun: 00 Vendor: DELL Model: PERC 6/i Rev: 1.22 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi0 Channel: 02 Id: 01 Lun: 00 Vendor: DELL Model: PERC 6/i Rev: 1.22 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: TEAC Model: DVD-ROM DV-28SW Rev: R.2A Type: CD-ROM ANSI SCSI revision: 05
查看RAID卡型號
# lspci | grep RAID 03:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 1078 (rev 04)
可以發現上面這台服務器的RAID卡是LSI的，服務器是DELL的，要查看更詳盡的信息就需要針對RAID卡在系統里面裝驅動了，如去LSI,或DELL網站可以找到對應的驅動。

搜到megaCLI可以試一下

通過DELL對應驅動查看

網上還有通用工具，如megasasctl，很久沒有更新了，也可以試一下
