Grid Infra Version:11.2.0.4
DB version: 11.2.0.4
Oracle Linux version : 6.4
We have a 2-node RAC cluster.
For a particual disk, usually whatever mentioned after ORCL: in v$asm_disk.PATH column and v$asm_disk.NAME are same.
Example:
PATH NAME
------ -----------
ORCL:DATA21 DATA21
But, in this particular cluster, I can see several disks whose label differs between $asm_disk.PATH column and v$asm_disk.NAME
Example:
PATH NAME
------------------------- --------------------
ORCL:ARCHIVE1 CMS_ARCHIVE1
SQL> select path, name, GROUP_NUMBER,TOTAL_MB/1024,FREE_MB/1024 from v$asm_disk order by 1,2 asc;
PATH NAME GROUP_NUMBER TOTAL_MB/1024 FREE_MB/1024
