192.168.85.7上面有两个Raid
一个Raid1, 500G，应该是两块盘，现在丢了一块，正确的槽位不知道是哪一个 另一个是Raid0，4TB，运行正常
现在在一个新槽位上插了一块硬盘，但是槽位不对，没有自动rebuild，状态是unconfiged good.
首先查一下丢失的盘
/opt/MegaRAID/MegaCli/MegaCli64 -Pdgetmissing -a0
得到参数Array 0，Row 1
首先进行替换，新盘的id是32:2，替换掉Array0 Row1的盘
/opt/MegaRAID/MegaCli/MegaCli64 -PdReplaceMissing -PhysDrv [32:2] -Array0 -row1 -a0
然后强制这块新盘开始重建
/opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -Start -PhysDrv [32:2] -a0
随时查看一下进度
/opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ShowProg -PhysDrv [32:2] -a0
上面已经走了5%了，走完就ok了。
