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.
