First of all:

Why is the vendor IBM? Shouldn't it be Dell?
Dell may make the library, but IBM made the drives. The LTO3 drives in my
Overland library are from HP.

That's the SCSI backplane in your server -- it has nothing to do with the
library.

I'm a bit confused about all these devices. I can't communicate with my PV
124T either on /dev/sg2 nor on /dev/sg7.
Well, sg2 is the tape drive itself and sg7, like I said, is the backplane
in the server. I'm guessing that the changer is on the same SCSI ID as
the tape drive but on another LUN. Add
'options scsi_mod max_luns=255' to /etc/modprobe.conf, remake the initrd,
and reboot. Let us know if that helps.
