昨晚，在具体故障尚未定位的情况下，EMC的硬盘坏了2块。
首先是一块RAID 5的硬盘坏了一块，然后一块Hot Spare硬盘顶上。

未几，Hot Spare盘又挂掉了，然后数据开始向原来坏掉的硬盘Equalizing。
这个Equalizing能否正确完成显然是个未知数:

马上Call EMC，喊人连夜换掉了两块硬盘。
坏掉的硬盘和并不属于前几日故障LUN，但是同在一个Storage Group之中，与先前的故障应该没有直接的关联。
目前发现一台主机的PowerPath存在问题，这个问题导致一路光纤通道出现问题，这个故障导致部分LUN的Trespass。
-The End-

碰到过EMC CX600频繁坏盘，半年中一个月1个，尽是Softmedia error .现在似乎好了,有可能升级firmware解决一些问题。
