AIX系统错误之--添加磁盘错误

AIX系统错误之--磁盘错误

系统环境：

操作系统：AIX 5.3.8

Oracle: Oracle 10gR2

案例分析：

在阵列上划分lun后，AIX系统识别后磁盘状态为defined状态：

[root@aix214:/]#lsdev -c disk

hdisk0 defined 06-08-02 Other FC SCSI Disk Drive

hdisk1 Available 08-08-00-3,0 16 Bit LVD SCSI Disk Drive

hdisk2 Available 06-08-02 Other FC SCSI Disk Drive

hdisk3 Available 06-08-02 Other FC SCSI Disk Drive

转换"Available"时报错：

[root@aix214:/]#mkdev -l hdisk0

Method error (/usr/lib/methods/cfgscsidisk):

0514-040 Error initializing a device into the kernel.

通过ODM库查询磁盘信息：

[root@aix214:/]#odmget -q"name=hdisk0" CuDv

CuDv:        name = "hdisk0"        status = 0         ；；flag id=0        chgstatus = 0        ddins = "scsidisk"        location = "06-08-02"        parent = "fscsi0"        connwhere = "1"        PdDvLn = "disk/fcp/osdisk"

[root@aix214:/]#odmget -q"name=hdisk2" CuDv（正常状态磁盘）

CuDv:        name = "hdisk2"        status = 1            ；；flag id=1        chgstatus = 0        ddins = "scsidisk"        location = "06-08-02"        parent = "fscsi0"        connwhere = "2"        PdDvLn = "disk/fcp/osdisk"

解决方法：（清除ODM信息）

系统重新启动后：

[root@aix214:/]#lsdev -c disk

hdisk0 Available 06-08-02     Other FC SCSI Disk Drivehdisk1 Available 08-08-00-3,0 16 Bit LVD SCSI Disk Drivehdisk2 Available 06-08-02     Other FC SCSI Disk Drivehdisk3 Available 06-08-02     Other FC SCSI Disk Drive

@至此，问题解决！
