mtx needs to talk to an sg device, not an st device. > when I do the same with sg0: (mtx -f /dev/sg0 inquiry) > I get: > Product Type: Tape Drive > Vendor ID: 'SEAGATE ' > Product ID: 'DAT 06241-XXX' That's your tape drive, not your changer. > scsi1 : ioc1: LSI53C1030, FwRev=01000400h, Ports=1, > MaxQ=222, IRQ=28 > Vendor: SEAGATE Model: DAT 06241-XXX Rev: 8110 > Type: Sequential-Access ANSI SCSI > revision: 03 If that's the only thing it picked up on this chain, it isn't seeing your changer. > any ideas? Do you know exactly how this changer is set up? Does the changer have a separate SCSI ID from the tape drive, or is it on a different LUN? Are you having any termination issues at the tape drive? Did you custom compile your kernel, and forget to check "scan all LUNs" in SCSI support. Also, after bootup, do '/sbin/lsmod'. Is the "sg" module loaded? If not, do 'modprobe sg' and then look at the last few lines of 'dmesg' output -- Does anything jump out there? -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
