AIX系統錯誤之--磁盤錯誤
來源：http://blog.csdn.net/yujin2010good/article/details/40075485
系統環境：
操作系統：AIX 5.3.8
Oracle: Oracle 10gR2
案例分析：
在陣列上劃分lun後，AIX系統識別後磁盤狀態為defined狀態：
[[email protected]:/]#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
轉換“Available”時報錯：
[[email protected]:/]#mkdev -l hdisk0
Method error (/usr/lib/methods/cfgscsidisk):
0514-040 Error initializing a device into the kernel.
通過ODM庫查詢磁盤信息：
[[email protected]:/]#odmget -q"name=hdisk0" CuDv
| 1 2 3 4 5 6 7 8 9 |
CuDv:
name = "hdisk0"
status = 0 ；；flag id=0
chgstatus = 0
ddins = "scsidisk"
location = "06-08-02"
parent = "fscsi0"
connwhere = "1"
PdDvLn = "disk/fcp/osdisk"
|
[[email protected]:/]#odmget -q"name=hdisk2" CuDv（正常狀態磁盤）
| 1 2 3 4 5 6 7 8 9 |
CuDv:
name = "hdisk2"
status = 1 ；；flag id=1
chgstatus = 0
ddins = "scsidisk"
location = "06-08-02"
parent = "fscsi0"
connwhere = "2"
PdDvLn = "disk/fcp/osdisk"
|
解決方法：（清除ODM信息）
系統重新啟動後：
[[email protected]:/]#lsdev -c disk
| 1 2 3 4 |
hdisk0 Available 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

@至此，問題解決！
