It is asking for the next "tape".   You apparently left off the 's'
flag which you want to use when you write to a file.  Otherwise it
assumes you are writing to a tape type of media and it tries to
guess how big the tape is based on other values you might give it - but 
if you don't tell it anything, it uses very old very small values 
for media size.     

So, anyway, you need the 'a' flag for dumps to a file.
