i have been having trouble with backups to a scsi ait tape drive.  i 
have tried using dump and tar and get back i/o errors as well as write 
protected and permission errors.  the tape drive will also lock-up after 
the i/o errors.  i thought it might be caused by a dirty tape drive so i 
cleaned it, but am still having problems.  i just entered in the 
following command:

tar cfv /dev/nrsa0 var

and this was the response:

tar: can't write to /dev/nrsa0 : Operation not permitted

an ls -l of the device shows:
crw-rw----  4 root  operator   14,   1 Jul  2 16:06 nrsa0

i am logged in as root when trying to create the backups.

do i possibly need to rebuild the device?  or is there something i need 
to do to configure the ait tapes - these are brand new tapes?
