/opt/MegaRAID/MegaCli/libstorelibir-2.so.14.07-0

查看帮助

/opt/MegaRAID/MegaCli/MegaCli64 -h

查看 Raid 控制器数量

/opt/MegaRAID/MegaCli/MegaCli64 -adpCount

查看 Raid 卡详细信息

/opt/MegaRAID/MegaCli/MegaCli64 -AdpAllInfo -aAll

查看连接 Raid 卡的全部硬盘信息

/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aAll  // 其中ALL意思是所有的控制器，此处也可以用0表示
/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aN // N可以根据Adapter #0来确定

获取指定磁盘信息

/opt/MegaRAID/MegaCli/MegaCli64 -pdInfo -PhysDrv[E0:S0,E1:S1,...] -aN|-a0,1,2|-aALL
  • N 表示 raid 卡编号
  • 0 表示第一块 raid 卡
  • ALL 表示所有的 raid 卡
  • E 表示 Enclosure Device
  • S 表示 Slot Number

全局热备

MegaCli64 -PDHSP -set -PhysDrv[E:S] -a0   添加全局热备
MegaCli64 -PDHSP -rmv -PhysDrv[E:S] -a0   删除全局热备
  • E: Enclosure Device ID
  • S: Slot Number

删除 Raid 组

/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdDel -L2 -force -a0

添加新的 Raid 0 磁盘

/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r0[32:5] WB Direct -a0
  • r0: raid0
  • WB Direct： 磁盘Write back

查看磁盘缓存策略

/opt/MegaRAID/MegaCli/MegaCli64 -LDGetProp -Cache
