帮忙看看是scsi总线问题还是磁盘问题

2台v490 通过scsi线连接到 sun jbod磁盘阵列
前段时间系统一直正常.这几天突然2台系统都在晚上报一些scsi的错误  但通过format看磁盘状态正常,磁盘阵列上指示灯正常,业务运行正常

按理说同时坏这么多硬盘的可能性很低. 可SCSI线连接又很紧 不可能松动  大家说说这会是什么原因??

JBOD的，等着高人回答
同时坏这么多盘的可能性很小，是什么存储？什么版本的系统？

You can check the speed to each scsi target with:

  # prtpicl -v | egrep "NAME=|sync-speed" | grep -v spindle
