I use commands on 2 machines to view:

DELL R710 Server: 4 SAS hard Drive 500GB, Total 2TB, after RAID10, left 1TB of capacity hard disk space.

[root@jxq-01 raid]#/opt/megaraid/megacli/megacli64-cfgdsply-aall|grep "RAID level" |tail-1|awk-f: ' {print $ ': "$}"

Raid Level:primary-1, Secondary-3, RAID level Qualifier-0

DELL R720 Server: A SAS hard drive 300GB

[Root@web opt]#/opt/megaraid/megacli/megacli64-cfgdsply-aall|grep "RAID level" |tail-1|awk-f: ' {print $ ': ' $} '

Raid level:primary-0, Secondary-0, RAID level Qualifier-0 #我这台主机是RAID 0

The RAID model corresponding table information is as follows:

Raid Level:primary-1, Secondary-0, RAID level Qualifier-0 "#代表Raid 1

Raid level:primary-0, Secondary-0, RAID level Qualifier-0 "#代表Raid 0

Raid Level:primary-5, Secondary-0, RAID level Qualifier-3 "#代表Raid 5

Raid Level:primary-1, Secondary-3, RAID level Qualifier-0 "#代表Raid10
