大家有没有碰到DS4300 存储诊断提示该错误呢?
环境: ds4300 接两台交换机 两个arry ,
登陆sm查看,发现所有lun链路都切到A控上了,通过手工可以切到B控上。
从日志查看,有一台交换机掉过电,也就是说发生切换了。起初配置LUN 的时候,默认都配置为B控(是不是和这个有关系)
那现在能否更改preferred path, 让链路更加均衡。存储也不在报错,现在手动更改路径后,recheck后,不管用?
报错依旧,大家看看哪里问题?
Possible causes include:
The controller failed a manually initiated diagnostic test and was placed Offline.
The controller was manually placed Offline using the Advanced >> Recovery >> Place Controller >> Offline menu option.
There are disconnected or faulty cables.
A Hub or Fabric switch is not functioning properly.
A host adapter has failed.
The storage subsystem contains a defective RAID controller
