The most recent Oracle 11g RAC installation ran into a INS-30507 error, that is, when the grid was installed to create the ASM Disk Group, no candidate disks were found, and Google did not find any clues to the N-Multiple installation instructions. If you encounter this problem, you might as well look down.
1. Error message and explanation
SEVERE: [FATAL] [INS-30507] Empty ASM disk group.
Cause:no disks were selected from a managed ASM disk group.
Action:select appropriate number of disks from a managed ASM disk group.
This explanation, given by Oracle, is too gripping to give any useful information.
