I just checked the config for the kernel supplied with 7.1 and SCSI tape support is enabled as a module. That's probably the case for other recent kernels, but I would suggest you check the config for the kernel you are running to be sure. It looks like you have enabled luns on the SCSI adapter. If you hadn't, I don't think it would have noticed the changer and you will not be able to use it as a changer. The device should be /dev/st0 (the rewind device - automatically rewinds on a close. There's also /dev/nst0 which doesn't rewind.) and is probably owned by root. I don't know anything about Netbackup, but if you ran it as root and it does a scan for devices when it starts, it should be able to find it as long as it understands the particular device you have. Are you sure Netbackup supports your Sony tape drive? Are there any configuration options in Netbackup that might help it figure out what device to use? Also, I would suggest using mt to see if you can make a tape in the tape drive do something (like forward space, backspace, or rewind). If not, do an lsmod to see if the st module is loaded and if not try doing a modprobe.
