If you ever deal with tapes on AIX, save the following two commands away:

        chdev -l rmt0 -a block_size=000    (act like a Unix tape drive)
and
        chdev -l rmt0 -a block_size=512    (act like an AIX tape drive)

The first is for dealing with any tapes other than AIX and the second
is for installing AIX tapes.  You can also use

        chdev -l rmt0 -a block_size=NNN

to make it act like a tape drive connected to "dd bs=NNN".

Depending on your environment, you probably shouldn't assume anything
about the what the block_size attribute is set to when you access the
tape.  Just get in the habbit of explicitly setting it yourself before
each use.
