errpt报DISK OPERATION ERROR，但使用正常，需要怎样处理？

sygdwg

AIX5。2操作系统，POWERPATH4。2，CX700存储，最近在对LUN从一个storage group移动到另一个storage group后，在系统中做importvg等对磁盘的系统级操作时，errpt中会报DISK OPERATION ERROR的错误。有时候有几行错误，有时候有几十行错误，但是应用的运行一点问题没有，请问这是否为严重问题，该如何操作，可以使系统中不再报错？\r\nerrpt\r\nDCB47997   0710093106 T H hdisk21        DISK OPERATION ERROR\r\nDCB47997   0707155506 T H hdisk55        DISK OPERATION ERROR\r\n\r\nerrpt -a\r\n---------------------------------------------------------------------------\r\nLABEL:                SC_DISK_ERR4\r\nIDENTIFIER:        DCB47997\r\n\r\nDate/Time:       Mon Jul 10 09:31:12 BEIS\r\nSequence Number: 523\r\nMachine Id:      \r\nNode Id:         \r\nClass:           H\r\nType:            TEMP\r\nResource Name:   hdisk21         \r\nResource Class:  disk\r\nResource Type:   CLAR_FC_raid10\r\nLocation:        U1.5-P1-I5/Q1-W5006016110602717-L11000000000000\r\nVPD:             \r\n        Manufacturer................DGC     \r\n        Machine Type and Model......RAID 10         \r\n        ROS Level and ID............0207\r\n        Serial Number...............\r\n        Device Specific.(SI)........CX700\r\n        Device Specific.(PQ)........00\r\n        Device Specific.(VS)........32000045D9CL\r\n        Device Specific.(UI)........60060160F95411000D1F64532E48D911\r\n        Device Specific.(FL)........0032\r\n        Device Specific.(Z0)........10\r\n        Device Specific.(Z1)........10\r\n\r\nDescription\r\nDISK OPERATION ERROR\r\n\r\nProbable Causes\r\nMEDIA\r\nDASD DEVICE\r\n\r\nUser Causes\r\nMEDIA DEFECTIVE\r\n\r\n        Recommended Actions\r\n        FOR REMOVABLE MEDIA, CHANGE MEDIA AND RETRY\r\n        PERFORM PROBLEM DETERMINATION PROCEDURES\r\n\r\nFailure Causes\r\nMEDIA\r\nDISK DRIVE\r\n\r\n        Recommended Actions\r\n        FOR REMOVABLE MEDIA, CHANGE MEDIA AND RETRY\r\n        PERFORM PROBLEM DETERMINATION PROCEDURES\r\n\r\nDetail Data\r\nPATH ID\r\n           0\r\nSENSE DATA\r\n0A00 2A00 01EB E020 0000 1004 0000 0000 0000 0000 0000 0000 0200 0300 0000 0000 \r\n0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 \r\n0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 \r\n0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 \r\n0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 \r\n0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 \r\n0000 0000 0000 0001 D9AE 0008 A080 0000 0006 0000 0000 0000 0000 0000 0000 0000 \r\n0000 0035 001D \r\n---------------------------------------------------------------------------\r\nLABEL:                SC_DISK_ERR4\r\nIDENTIFIER:        DCB47997\r\n\r\nDate/Time:       Fri Jul  7 15:55:07 BEIS\r\nSequence Number: 522\r\nMachine Id:      \r\nNode Id:         \r\nClass:           H\r\nType:            TEMP\r\nResource Name:   hdisk55         \r\nResource Class:  disk\r\nResource Type:   CLAR_FC_raid10\r\nLocation:        U1.5-P2-I8/Q1-W5006016010602717-LF000000000000\r\nVPD:             \r\n        Manufacturer................DGC     \r\n        Machine Type and Model......RAID 10         \r\n        ROS Level and ID............0207\r\n        Serial Number...............\r\n        Device Specific.(SI)........CX700\r\n        Device Specific.(PQ)........00\r\n        Device Specific.(VS)........30000045C8CL\r\n        Device Specific.(UI)........60060160F95411000B1F64532E48D911\r\n        Device Specific.(FL)........0030\r\n        Device Specific.(Z0)........10\r\n        Device Specific.(Z1)........10\r\n\r\nDescription\r\nDISK OPERATION ERROR\r\n\r\nProbable Causes\r\nMEDIA\r\nDASD DEVICE\r\n\r\nUser Causes\r\nMEDIA DEFECTIVE\r\n\r\n        Recommended Actions\r\n        FOR REMOVABLE MEDIA, CHANGE MEDIA AND RETRY\r\n        PERFORM PROBLEM DETERMINATION PROCEDURES\r\n\r\nFailure Causes\r\nMEDIA\r\nDISK DRIVE\r\n\r\n        Recommended Actions\r\n        FOR REMOVABLE MEDIA, CHANGE MEDIA AND RETRY\r\n        PERFORM PROBLEM DETERMINATION PROCEDURES\r\n\r\nDetail Data\r\nPATH ID\r\n           0\r\nSENSE DATA\r\n0A00 2A00 00B8 74E8 0000 1004 0000 0000 0000 0000 0000 0000 0200 0300 0000 0000 \r\n0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 \r\n0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 \r\n0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 \r\n0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 \r\n0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 \r\n0000 0000 0000 0000 6471 0006 F9C0 0000 0006 0000 0000 0000 0000 0000 0000 0000 \r\n0000 0035 001D

去问EMC的工程师，你得到的答复肯定是“不用管它，这是误报”

mygod1997

是用raid做的吗？最好连根线进去看看

yddll

我们这儿从开始安装到现在,一直就有这个问题,EMC的人说是正常,不用管它.\r\n\r\n我一直比较担心的是,如果有一天我们习惯这些报错了,真有一天真的有问题了,却以为是正常的,那就麻烦了.......

hgh25emus

我也遇到同样的问题，开始emc的工程师来，做了下修改，后来好了，最近又有这种报错，但对应用是不影响。\r\n的。其实你会发现不一定importvg 会引发这种出错，我重启ha或数据库都会出这种错的。\r\n我有个他们当初的处理文档给你不知道你敢不敢用？

这个问题最后的处理结果，希望能告知大家。

hgh25emus

Problem: \r\nWhy do LUNZ devices appear on an AIX host even though storage is attached?\r\nProblem: \r\nLUNZ devices appear after running cfgmgr, but were not there previously.\r\nChange: \r\nThe ALU (Array LUN Unit) associated with HLU (Host LUN Unit) 0 was removed from the Storage Group.\r\nChange: \r\nCLARiiON LUNs attached to host.\r\n这个就是问题产生的原因，所以要消除LUNZ devices

正常现象，但host中出现lunz设备本身就说明有问题

我这边用fix 1 这种方法是不好用的， 用的是第二种方法，bind一个小lun。
