AIX system error one disk error

AIX system error – disk error

System environment:
Operating system: AIX 5.3.8
The Oracle: Oracle 10 gr2
Case Study:
After luns are divided on the array, the disk state is defined after the AIX system recognizes it:
[[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
Conversion “Available” times wrong:
[[email protected]:/]#mkdev -l hdisk0
Method error (/usr/lib/methods/cfgscsidisk):
014-040 Error initializing a device into the kernel.

Query disk information through THE ODM library:
[[email protected]:/]#odmget -q”name=hdisk0″ CuDv

Solution :(clear ODM information)

After system restart:
[[email protected]:/]#lsdev -c disk
