I have a Tandberg T40+ Tapeloader with HP LTO-5 tape drive connected to "QLogic Corp. ISP2532-based 8Gb Fibre Channel to PCI Express HBA" on a Dell 2950 running Ubuntu Server 10.10. The kernel version is 2.6.35-24-server. The autoloader device number changes sometimes with reboot. When I installed the server it was /dev/sg4 and now it is /dev/sg2. The tape drive is at /dev/st0 and /dev/nst0.
My question is how can I fix the problem of device number changing with reboots?
It also seems the tape is not using the st driver but is using generic SCSI driver, How can I force the tape drive to use the st driver? I already have the stinit.def file under /etc.
stinit.def
