Accidently deleted redo log files on production system - Help !

I'm half cooked stupid DBA who has accidentaly deleted redo log files under one directory.

DB Version: 7.3

The redo log files are 2 members in each group. I deleted one member from each group accidently as they were under one directory.

I was able to bring up the database and it is running alright. But I think this means that now we have have single point of failure. I want to clean this mess because if something happens or finds out, my credibility will get f--ked-up.

I've tried to 'alter database add logfile member '/u01/.../redonna.log' to group n';
