Possible ASM corruption or Misreporting Issue ?

Hi Folks,

I am getting some conflicting information when I query the v$asm_disk view. The header status for all 114 disks should be "Member". But ,with the exception of three disks, all other disks appear as "Candidates"?

There are no errors in either the RDBMS or the ASM alert logs.

The database is working fine for the time being.

Has anybody experienced this discrepancy? Is it a case of disk header corruption? or simple misreporting? And more importantly, how can I fix the problem?

The details are as follows

O/S: AIX 5.3.12.1
Database: 11.2.0.3
select DISK_NUMBER,HEADER_STATUS,substr(PATH,1,20),label 
from v$asm_disk;

*Output:*

         17 CANDIDATE    /dev/rhdisk10
         18 CANDIDATE    /dev/rhdisk100
         19 CANDIDATE    /dev/rhdisk101
         20 CANDIDATE    /dev/rhdisk102
         21 CANDIDATE    /dev/rhdisk103
         22 CANDIDATE    /dev/rhdisk104
         23 CANDIDATE    /dev/rhdisk105
         24 CANDIDATE    /dev/rhdisk106
        ...
        112 MEMBER       /dev/rhdisk147
        113 MEMBER       /dev/rhdisk148
        114 MEMBER       /dev/rhdisk149
Thanks in advance
