AIX system ERROR--disk error



AIX System ERROR--disk error

System Environment:

operating system: AIX 5.3.8

oracle:oracle 10GR2

Case Analysis :

after the LUNs are partitioned on the array, the AIX system recognizes that the disk status is defined state:

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

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

Hdisk1 Available 08-08-00-3,0-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

Convert "Available" times wrong:

[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

1 2 3 4 5 6 7 8 9

Cudv:name = "Hdisk0" status = 0;; flag id= 0 chgstatus = 0 ddins = "scsi Disk "location =" 06-08-02 "parent =" Fscsi0 "Connwhere =" 1 "pddvln =" disk/fcp/o Sdisk "

[root@aix214:/] #odmget-Q "Name=hdisk2" CUDV (normal state disk)

1 2 3 4 5 6 7 8 9

Cudv:name = "Hdisk2" status = 1;; flag id= 1 chgstatus = 0 Ddins = "s Csidisk "location =" 06-08-02 "parent =" Fscsi0 "Connwhere =" 2 "PDDVLN =" DISK/FC P/osdisk "

Workaround: (Clear ODM information)

after the system restarts:

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

1 2 3 4

Hdisk0 Available 06-08-02 Other FC SCSI disk drive Hdisk1 Available 08-08-00-3, 0-Bit LVD SCSI disk Driv E hdisk2 Available 06-08-02 other FC SCSI disk drive HDISK3 Available 06-08-02 other FC SCSI disk drive

@ so far, problem solved.
