raid6arrays中哪个磁盘坏了

服务器：Ubuntu Lucid
RAID控制器：Adaptec 3805
HP Proliant DL180 G5硬件上的RAID6中有8个磁盘

我的kern.log告诉我在sdb上有一个错误，如下所示：

[2740390.344436] sd 4:0:1:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [2740390.344439] sd 4:0:1:0: [sdb] Sense Key : Hardware Error [current] [2740390.344442] sd 4:0:1:0: [sdb] Add.

arcconf命令告诉我所有的磁盘状态都在线＆条带失败：是的

我怎样才能确定哪个磁盘坏了8磁盘raid6arrays？

• mdadm raid6恢复从一个驱动器读取更多？
• RAID6设置 – 添加额外的驱动器
• 如何诊断间歇性缓慢的RAID数据传输速率？
• 从第一次失败重新同步期间删除第二个RAID6驱动器？
• 恢复高度降级的RAIDarrays

修正： 2012年5月2日 – 添加如下：

/ usr / local / sbin / arcconf getconfig 1 AL
