Oracle Error Message
ORA-15067: command or option incompatible with diskgroup redundancy
Reason for the Error
An attempt was made to use a feature which is not permitted by the diskgroup’s redundancy policy. Common examples are forcibly dropping a disk from an EXTERNAL REDUNDANCY diskgroup, using the FAILGROUP clauses with an EXTERNAL REDUNDANCY diskgroup, or using invalid template attributes.
Omit the option from the command.
