1.顯示Rebuid進度
/opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ShowProg -physdrv[20:2] -aALL
2.查看E S
/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aAll -NoLog | grep -Ei "(enclosure|slot)"
3.查看所有硬盤的狀態
/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aAll -NoLog
4.查看所有Virtual Disk的狀態
/opt/MegaRAID/MegaCli/MegaCli64 -LdPdInfo -aAll -NoLog
RAID Level對應關系：
| RAID Level : Primary-1, Secondary-0, RAID Level Qualifier-0 | RAID 1 |
| RAID Level : Primary-0, Secondary-0, RAID Level Qualifier-0 | RAID 0 |
| RAID Level : Primary-5, Secondary-0, RAID Level Qualifier-3 | RAID 5 |
| RAID Level : Primary-1, Secondary-3, RAID Level Qualifier-0 | RAID 10 |
5.在線做Raid
/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r0[0:11] WB NORA Direct CachedBadBBU -strpsz64 -a0 -NoLog /opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r5 [12:2,12:3,12:4,12:5,12:6,12:7] WB Direct -a0
6.點亮指定硬盤（定位）
/opt/MegaRAID/MegaCli/MegaCli64 -PdLocate -start -physdrv[252:2] -a0
7.清除Foreign狀態
/opt/MegaRAID/MegaCli/MegaCli64 -CfgForeign -Clear -a0
8.查看RAID陣列中掉線的盤
/opt/MegaRAID/MegaCli/MegaCli64 -pdgetmissing -a0
9.替換壞掉的模塊
/opt/MegaRAID/MegaCli/MegaCli64 -pdreplacemissing -physdrv[12:10] -Array5 -row0 -a0
10.手動開啟rebuid
/opt/MegaRAID/MegaCli/MegaCli64 -pdrbld -start -physdrv[12:10] -a0
11.查看Megacli的log
/opt/MegaRAID/MegaCli/MegaCli64 -FwTermLog dsply -a0 > adp2.log
12.設置HotSpare
/opt/MegaRAID/MegaCli/MegaCli64 -pdhsp -set [-Dedicated [-Array2]] [-EnclAffinity] [-nonRevertible] -PhysDrv[4:11] -a0 /opt/MegaRAID/MegaCli/MegaCli64 -pdhsp -set [-EnclAffinity] [-nonRevertible] -PhysDrv[32：1}] -a0
13.關閉Rebuild
/opt/MegaRAID/MegaCli/MegaCli64 -AdpAutoRbld -Dsbl -a0
14.設置rebuild的速率
/opt/MegaRAID/MegaCli/MegaCli64 -AdpSetProp RebuildRate -30 -a0
