AIX系统错误之--磁盘错误
来源：http://blog.csdn.net/yujin2010good/article/details/40075485
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
|
1

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
|
1

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！
