I don't know if this would be your total solution, but I would start
with this: your STK firmware could stand to be upgraded. If you go to
http://support.veritas.com/menu_ddProduct_NETBACKUPDC.htm and click on
'compatibility lists', click down and you'll see the STK 9710 was
started testing at firmware version 1.2. We are running with 1.9.52, the
latest tested version of the firmware (BTW: DON'T use the 2.x firmware
from STK). Upgrading it is a breeze, just get a floppy disk with the
version of firmware you want from STK, stick it in the floppy drive,
then push the IPL button.
