Issue: What do I need to do to get a tape autoloader to work on an RHEL 3 machine
Answer: You need to install 'mtx' and 'sg3_utils' by doing 'up2date mtx; up2date sg3_utils', then reboot.
Issue: My computer running RHEL 3 (Red Hat Enterprise Linux 3) does not detect the media changer on my Quantum Superloader 3 tape library. Or it does not detect a WD MyBook USB hard drive, with /proc/scsi/scsi listing only the 'Enclosure' part.
Answer: http://spiralbound.net/2006/10/16/making-rhel-3-see-multiple-luns - you need to add a line to /etc/modules and rebuild your initrd to tell the kernel to look for multiple SCSI devices exposed by a single physical machine. Since USB, for added irritation, is part of the SCSI subsystem, this is also needed for USB peripherals that expose several USB devices.
By the way, the 'Enclosure' for a WD MyBook USB hard drive is the glowing blue button on the front.
Issue: Having done this, I get 'input/output error' messages from Amanda and 'st0: incorrect block size' messages appear in dmesg
Answer: You need to issue a 'mt -f /dev/nst0 setblk 0' command, possibly every time that you load a tape
Issue: mtx doesn't detect the mail-slot on my Quantum Superloader 3 tape library
Answer: No. It doesn't. Use the controls on the front to load and eject tapes from the library. Sorry.
It has taken two of us most of the day so far to answer these questions; Google gets inordinate numbers of references to the questions and very few to the answers. I *hope* that Google will now index this page and my successors will be able to get all of this at once.
