One of the AIX system errors-disk errors

System environment:

Operating system: AIX 5.3.8

Oracle: Oracle 10gR2

Case study:

After dividing the lun on the array, the disk state recognized by the AIX system is defined:

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

Hdisk0 defined 06-08-02 Other FC SCSI Disk Drive

Hdisk1 Available 08-08-00-3 hdisk1 Available 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

Error in converting "Available" Times:

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

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

0514-040 Error initializing a device into the kernel.

Query disk information through the ODM library:

[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 (normal state disk)

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

After the system restarts:

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

Hdisk0 Available 06-08-02 Other FC SCSI Disk Drivehdisk1 Available 08-08-00-3 Bit LVD SCSI Disk Drivehdisk2 Available 016 Bit LVD SCSI Disk Drivehdisk2 Available 06-08-02 Other FC SCSI Disk Drivehdisk3 Available 06-08-02 Other FC SCSI Disk Drive@ so far, problem solved!
