昨晚,在具体故障尚未定位的情况下,EMC的硬盘坏了2块。链接:https://www.eygle.com/archives/2007/04/emc_disk_failed2.html
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-

万幸,没有丢数据!
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。
