磁盘错误,请教高手.

Informix 出现下面的错误, 存储设备是阵列A1000, 做的是RAID5, 现在一个盘有告警.
如果换掉的话,会影响数据吗?
用的是裸设备的方式.

onstat -d 看看
如果是rootdbs的话，很严重，用备份来恢复吧。

不行呀,老大.是硬件问题吗?

$ onstat -d
shared memory not initialized for INFORMIXSERVER 'dmadbs'

啊？rootchunk1应该是有问题了。你在'/opt/informix/chunks/目录下用“lc -l rootchunk1”看看是具体链接的是什么盘？该盘的其他分区还能用不？不过估计是硬盘坏了。

idsboy

报的是sanity错误，chunk已经坏了~~~~
raid5换个硬盘数据不会受到影响~~~

看来只好换硬盘了
