ORA-15072

This command requires at least %0!s regular failure groups, discovered only %1!s.

Cause

An attempt was made to create either a NORMAL REDUNDANCY disk group for which fewer than two regular failure groups were both specified and discovered, or a HIGH REDUNDANCY disk group for which fewer than three regular failure groups were both specified and discovered, or an EXTERNAL REDUNDANCY disk group for which only quorum disks were both specified and discovered.


Action

Check that the command does specify the required number of failure groups, and that all of the specified disks are discovered by Oracle ASM. A query of the V$ASM_DISK view will show which disks are discovered by Oracle ASM. Note that a quorum failure group will not be used as a regular failure group. An EXTERNAL REDUNDANCY disk group requires at least one regular disk.
