a couple of things to keep in mind when using tar on apollo's:
1) unless the tape has been rewound tar will balk giving you
the device not found error. in order to rewind use the rbak command as
follows
/com/rbak -dev ct -rewind
now you are ready to use tar but wait....
2) /dev/rct8 use QIC-24 format which is fine for transfer
to suns, using rst8 and iris nodes using rmt1 but you
have to realize that iris' do a byte swapping which has to be
UNDONE so to speak. so let's assume you have written
out your tape using /dev/rct8 at the apollo end when you try to
read the tape at the iris end do the following:
dd conv=swab if=/dev/rmt1 | tar -xvf -
and the restoration should take place. going the other way
means having to reverse the order of the dd and the tar operations
