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.
