p650双机,通过两台brocade交换机连接共享存储,用cambex做路径冗余.正常情况下a机接管阵列上的共享卷组.当b机接管共享卷组后,a机重启动会遇到不能识别共享阵列的问题,机器停在检测fc卡不能完成启动.拔掉光纤线后重启动,插线执行cfgmgr,有时顺利检测到共享阵列的磁盘,有时检测不到.基本环境和问题如上
突发问题:共享卷组已接管到b机.卷组用做db2数据库的裸设备表空间容器.下午突然出现系统高io等待,系统错误日志如下,持续短时间后数据库崩溃.检查表空间状态发现共享卷组上属于数据库用户的lv属主被更改为root用户.更改属主后备份数据库,开始读写速度正常,20分钟后出现数据基本不读写的情况,持续30分钟后又恢复正常读写速度.此时未注意cambex活动路径.数据备份完成后重新启动阵列和b机,cambex只识别到一条路径.到目前为止数据读写正常.
请问该采取哪些测试以确定问题发生的原因.或者从此错误日志可以判断出哪些问题,请高手指教,晚上好做测试.阵列为netstor9210,本身没有报任何错误信息.
