I setup a single instance database with a DATA and an FRA disk group. Both groups use external redundancy. We had a power outage here yesterday, and the system crashed. When trying to restart the database, it was discovered the the disk groups were offline. I tried various commands in the ASM database itself to online the disks, but each time an error was thrown. However when I checked again both disk groups were online. It seems unlikely anything I did would have on-lined the disk groups as an error was thrown for everything I tried I checked with my system administrator and she had done nothing.

Is alter diskgroup the command that should be used in this situation, or am I way off.
