1、megaraid硬RAID卡命令管理手册二、下载、安装MegCli下载地址：wget http:/ -ivh MegaCli-8.00.48-1。i386。rpm故障硬盘修复（添加新硬盘或阵列)#-PDMakeGood是改变状态由Unconfigured bad变成Unconfigured good-PhysDrv252:2 是硬盘信息内第一个数字是Enclosure Device ID，第二个数字是Slot Number#-a0 是Adapter #01. /opt/MegaRAID/MegaCli/MegaCli64 -PDMakeGood -PhysDrv252：2 a0硬盘变为Unco
2、nfigured good之后加入阵列2. /opt/MegaRAID/MegaCli/MegaCli64 LDRecon Start r5 -Add -PhysDrv252:2 L0 a03. 等待重建，大约需要2小时Reconstruction : Completed 0, Taken 1 min.使用/opt/MegaRAID/MegaCli/MegaCli64命令会在当前目录生成日志文件可以加上 NoLog参数取消日志三使用命令及参数命令使用：/opt/MegaRAID/MegaCli/MegaCli64 LDInfo Lall -aALL 查raid级别#/opt/MegaRAID/
