点亮/关闭硬盘灯
[root@idc-center009 ~]# /opt/MegaRAID/MegaCli/MegaCli64 PdLocate start physdrv[134:10] -a0 Adapter: 0: Device at EnclId-134 SlotId-10 -- PD Locate Start Command was successfully sent to Firmware Exit Code: 0x00
判断硬盘 槽位和盘符/dev/sdxxxx的关系
/opt/MegaRAID/MegaCli/MegaCli64 cfgdsply aall | grep -Ei 'Target Id|Slot|Device ID|Error|Inquiry'
看 Target Id 与 lsscsi | grep disk 输出中第一列第二个:后面的ID做对比。 相同为同一块盘
系统内模拟踢掉硬盘 (删除某个RAID)

MegaCli64 -CfgLdDel -LX -a0
X是第几个阵列(VD号:Virtual Drive: X);0表示第一个阵列。
例如:
/opt/MegaCli/MegaCli64 -CfgLdDel -L1 -a0 删除第一个逻辑盘
将物理盘下线和上线
# MegaCli64 -PDOffline/PDOnline -PhysDrv [E:S] -a0
下线(failed状态的盘可以下线)
# MegaCli64 -PDOffline -PhysDrv[252:7] -a0
上线
# MegaCli64 -PDOnline -PhysDrv[252:6] -a0
13.在线添加磁盘
# MegaCli64 -LDRecon -Start -r5 -Add -PhysDrv[252:7] -L0-a0
查看扩容的进度
# MegaCli64 -LDRecon -progdsply -L0 –a0
