简介

将一块硬盘做成单盘raid0，关机拔掉硬盘，将服务器重启后，将硬盘插入

操作环境

首先用fdisk看看能否看到硬盘，看不到，然后用MegaCli64看物理盘是否存在

通过以下命令看到物理硬盘是在的，但状态是Foreign

执行状态检测命令：

[root@meetbill ~]# /opt/MegaRAID/MegaCli/MegaCli64 -pdlist -aall |grep 'Firmware state'

执行导入命令

[root@meetbill ~]# /opt/MegaRAID/MegaCli/MegaCli64 -CfgForeign -Import -aall

再次执行状态检测命令：

[root@meetbill ~]# /opt/MegaRAID/MegaCli/MegaCli64 -pdlist -aall |grep 'Firmware state'
