Find out what the correct name of your tape device is (it probably isn't /dev/tapedev; on my machine (a Sun), it is /dev/rmt/0 -- your name will probably be different). Then alter the tape device configuration in OnLine to use the device (set the size correctly too) and do the backups. Note that the ontape command you mention is a system archive, not backing up the logical logs. You need to use 'ontape -a' to do an automatic backup of the logical logs, or 'ontape -c' to do continuous backups of the logical logs. Alternatively, but not really something I'd recommend, you can set the backup device to /dev/null, *BUT* you must understand that this throws away information that will be needed if your system crashes. If you do this, you still need to find out the tape device and you need to do the level 0 archive, and you will need to arrange to back up your logical logs properly just as soon as you possibly can. This will get you on the road, but without any safety belts. You need to get trained in OnLine Administration fast! It is not sensible to try installing such a system without understanding what the various configuration parameters do. For example, there's a fairly high probability that you do not have enough log space configured for your application, especially if you used the OnLine default settings.
