the tar problem reported is not an uncommon one, about not being able to
open the device. what one has to do is to make certain that the tape has be 
rewound to its starting position.  this can be done using the AEGIS rbak command.
assuming your at one of the unix shells type the following:
   /com/rbak -dev ct -rewind

once that is done then you can tar to your hearts content. i strongly recommend
using /dev/rct8 as it rewinds on finishing your archive; /dev/rct12 does not though
this may be what you want.  as a sidebar to this if you find yourself have to transfer
files to and from SUNs specify /dev/rst8 at the SUN side. this will write things
out using QIC-24. hope this is of some help.
