The destination of ontape -s is determined by TAPEDEV; the destination of ontape -a or ontape -c is determined by LTAPEDEV. But perhaps more to the point is whether, having set TAPEDEV to a valid device, the logical logs are actually stored with an ontape -s. The answer is, some of them are. That is, whatever is actually in use at the time the archive was started. This is so that, if you do only a physical restore of the archive, and don't roll forward any logs, OnLine can roll back any transactions that were open at the time of the archive, and bring your system back up in a state of transactional integrity. Beyond that, you have to back up your logical logs using ontape -a or ontape -c in order to recover past the point where the archive started.
