/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -Hsp[1:5] -a0
创建阵列，不指定热备
/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -a0
创建一个raid10阵列，由物理盘2,3和4,5分别做raid1，在将两组raid1做raid0
/opt/MegaRAID/MegaCli/MegaCli64 –CfgSpanAdd –r10 –Array0[1:2,1:3] –Array1[1:4,1:5] WB Direct -a0
