一台v240的机器，用iostat -E发现sd0上有Hard Errors，Transport Errors，具体内容如下，是不是第一块硬盘坏了，如果不是，怎样找出是哪块坏了呢，先谢谢大家了

Answer 1

sd0 has several media error and twice "Predictive Failure Analysis" is reported , which should be replaced.

Media Error: 10 Device Not Ready: 0 No Device: 2 Recoverable: 0
Illegal Request: 0 Predictive Failure Analysis: 2

to locate sd0, you need find out sd0's physical address and then decode its physical location.

such as:
# grep sd /etc/path_to_inst | grep 0

"/pci@8,700000/scsi@6/sd@0,0" 0 "sd"

Answer 6

楼上正解啊

Answer 7

不一定，看看format状态，dmesg信息中的这个盘的坏块报错的块是否是同一个，可以用format进行repair，还有就是会是否有用SVM做卷管理，可以看看metstat，metadb的信息！

Answer 8

回楼上的，是不是确定是第一块坏了呢？

Answer 9

坏可能性很大，换吧！
