描述：对于RAID卡识别到磁盘损坏，但实际磁盘未损坏的情况，可使用此方法重新导入。

1.查看磁盘状态：

/opt/MegaRAID/MegaCli/MegaCli64-PDList -a0|grep "Firmware state"

状态为：Firmware state: Unconfigured(bad)

2.将磁盘设置为good

/opt/MegaRAID/MegaCli/MegaCli64 -PDMakeGood -PhysDrv[8:9] -a0

3.再次查看此磁盘状态

/opt/MegaRAID/MegaCli/MegaCli64 -PDList -a0|grep "Firmware state"

Firmwarestate: Unconfigured(good), Spun Up

有两种业务场景进行修复 一个是执行外来盘导入进行自我修复，第二个是变成热备盘

执行进行外来盘导入

/opt/MegaRAID/MegaCli/MegaCli64-CfgForeign -Import -aall

第二种 可以看到该盘状态已经变成good了，现在就可以在线将该硬盘设置成热备盘了。

/opt/MegaRAID/MegaCli/MegaCli64-PDHSP -Set -PhysDrv[ 0:4] -a0

最后再查看硬盘状态，发现状态异常的盘已经修复成功了。

/opt/MegaRAID/MegaCli/MegaCli64  -PDList -aALL|grep "Firmware state"

查看磁盘重构状态:

/opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ShowProg -PhysDrv [1:5] -a0

Hotspare, Spun down状态修复UP步骤

某次远程时用MegaCli工具发现热备盘处理Hotspare, Spun down状态，如下图

解决方法：把这个hotspare删除了，再添加一次。注意物理设备和槽位id，如下8为EnclosureDevice ID，11为Slot Number

/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP rmv PhysDrv[8:11] -a0Adapter: 0: Remove PhysicalDrive at EnclId-8 SlotId-11 as Hot Spare Success.Exit Code: 0x00

/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP  Set PhysDrv[8:11] -a0Adapter: 0: Set Physical Driveat EnclId-8 SlotId-11 as Hot Spare Success.Exit Code: 0x00

添加后再查看，发现已经 Spun Up了

/opt/MegaRAID/MegaCli/MegaCli64 -AdpSetProp -AlarmSilence –a0
