  /opt/MegaRAID/MegaCli/MegaCli64 AdpSetProp -Enablejbod -0 -aALL
  

• 删除逻辑盘映射关系

  dmsetup remove_all
  

• 清除所有逻辑盘

  /opt/MegaRAID/MegaCli/MegaCli64 -CfgLdDel -LAll -aAll
  

• 修改raid状态(10:槽位号，14:enclosure id, 0: adapter id)

  /opt/MegaRAID/MegaCli/MegaCli64 -PDMakeGood -PhysDrv[14:10] -a0
  
  /opt/MegaRAID/MegaCli/MegaCli64 -PDoffline -PhysDrv[14:10] -a0
  
  

• 创建raid(0,1,5)

  /opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r{}[{}] {} NORA -a{}
  

• 创建raid10

  /opt/MegaRAID/MegaCli/MegaCli64 -CfgSpanAdd -r10 -Array0[32:0,32:1] -Array1[32:2,32:3] -Array2[32:4,32:5] -Array3[32:6,32:7] -Array4[32:8,32:9] -Array5[32:10,32:11] WB NORA -a0
  

• 初始化raid

  /opt/MegaRAID/MegaCli/MegaCli64 -LDInit -Start -LAll -a0
  

• 验证raid

  /opt/MegaRAID/MegaCli/MegaCli64 -LDInfo  -Lall -aAll | grep 'RAID Level'
  

• 打开热备份自动切换

  /opt/MegaRAID/MegaCli/MegaCli64 -AdpAutoRbld -Enbl -aall
