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!
