This is one of those autoloaders where the tape drive and the library share a SCSI ID, but are on different LUN's - specifically the library should be on LUN 1. Apparently since so many devices like this are broken, recent kernels don't probe beyond the first LUN, so it's not detecting the library. My /proc/scsi/scsi output: Attached devices: Host: scsi4 Channel: 01 Id: 00 Lun: 00 Vendor: MegaRAID Model: LD 0 RAID1 70G Rev: 1L47 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi5 Channel: 00 Id: 05 Lun: 00 Vendor: HP Model: C5713A Rev: H910 Type: Sequential-Access ANSI SCSI revision: 02 I read somewhere that this shouldn't be a problem with RHEL 4, but I can't seem to get it detected. I tried to add options scsi_mod max_scsi_luns=6 to modprobe.conf and regenerated initrd - no change. Tried adding max_luns=6 max_report_luns=6 to the kernel line in grub.conf, no change. I tried to manually add it by doing: echo "scsi add-single-device 0 0 5 1" > /proc/scsi/scsi but again, no change. Any suggestions? Am I on the right track and just doing something wrong? I know recompiling the kernel is not the best thing, but not sure what to do here.
