裸机维护

进入BIOS

ipmitool chassis bootdev bios  

ipmitool chassis power reset 

浪潮禁用板载网卡图示如下

 

 点亮/关闭硬盘灯

例如我想给Enclosure Device ID: 134，Slot Number: 10的硬盘点灯。 那么只需要执行如下命令：

[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
