Check to see if the mount point it up and available first. If so shutdown the instance and copy the files to you can always restart the recovery. If it is not up fix the mount point issue then copy the files. Finally try a recover database and hope there is enough data in redo logs to have a successful recovery. If the database opens shut it down immediately and perform a backup and put it into archive log mode for the future.
