# Explanation of Raid Levels:
['Primary-0, Secondary-0, RAID Level Qualifier-0'] = RAID-0
['Primary-1, Secondary-0, RAID Level Qualifier-0'] = RAID-1
['Primary-5, Secondary-0, RAID Level Qualifier-3'] = RAID-5
['Primary-6, Secondary-0, RAID Level Qualifier-3'] = RAID-6
['Primary-1, Secondary-3, RAID Level Qualifier-0'] = RAID-10
E jogo:
$ sudo /opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -Lall -aALL | grep RAID
RAID Level : Primary-1, Secondary-0, RAID Level Qualifier-0
RAID Level : Primary-1, Secondary-3, RAID Level Qualifier-0
$ sudo ./megasasctl
a0d0 136GiB RAID 1 1x2 optimal
a0d1 272GiB RAID 10 2x2 optimal
