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\r\n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.\r\n\r\n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.\r\nLABEL: LVM_IO_FAIL\r\nIDENTIFIER: 613E5F38\r\n\r\nDate/Time: Tue Dec 18 00:18:32 BEIS\r\nSequence Number: 33232\r\nMachine Id: 0050BE4C4C00\r\nNode Id: jlserver2\r\nClass: H\r\nType: PERM\r\nResource Name: LVDD \r\nResource Class: NONE\r\nResource Type: NONE\r\nLocation: \r\n\r\nDescription\r\nI/O ERROR DETECTED BY LVM\r\n\r\nProbable Causes\r\nPOWER, DRIVE, ADAPTER, OR CABLE FAILURE\r\n\r\n Recommended Actions\r\n RUN DIAGNOSTICS AGAINST THE FAILING DEVICE\r\n\r\nDetail Data\r\nPHYSICAL VOLUME DEVICE MAJOR/MINOR\r\n0030 0001 \r\nERROR CODE AS DEFINED IN sys/errno.h\r\n 16\r\nBLOCK NUMBER\r\n 499826968\r\nLOGICAL VOLUME DEVICE MAJOR/MINOR\r\n002F 0003 \r\nPHYSICAL BUFFER TRANSACTION TIME\r\n 128\r\nSENSE DATA\r\n0000 0000 000E E560 0050 B8EC 0000 4C00 0000 0100 789B 2524 0050 B8EC 789B 03D5 \r\n0000 0000 0000 0000 \r\n\r\nLABEL: SC_DISK_ERR2\r\nIDENTIFIER: B6267342\r\n\r\nDate/Time: Tue Dec 18 00:18:32 BEIS\r\nSequence Number: 33227\r\nMachine Id: 0050BE4C4C00\r\nNode Id: jlserver2\r\nClass: H\r\nType: PERM\r\nResource Name: hdisk5 \r\nResource Class: disk\r\nResource Type: IFT\r\nLocation: U0.1-P2-I5/Q1-W220000D023000008-L1000000000000-W220000D023000008-L1000000000000\r\nVPD: \r\n Manufacturer................IFT \r\n Machine Type and Model......F16F-S2A2 \r\n Part Number.................9 Infortrend\r\n ROS Level and ID............33343252\r\n Serial Number...............44F3D81B\r\n EC Level.....................
