ORA-00214: controlfile inconsistant

[yxez]

ohhh boy, then start doing a cold backup now at least u will have
a fallback if u encounter more error afterwards.
I guess the system was writing on the first control file when the
power failed, so it was not able to sync in to the other control files.
You may try to startup mount and recover database.
But wait for davey and the other gurus they might have a better
solution but as far as my knowlegde is concerned, i guess this
will also what they will tell you
