These days it's easiest to find this information from sysfs. Under /sys/bus/scsi/devices you'll find sub-directories that list all SCSI devices by their bus address (in host:bus:target:lun format). E.g. if I want to find out what device 3:0:0:1 on my system is I can look at: # ls /sys/bus/scsi/devices/3\:0\:0\:1/ block:sdd delete dh_state generic iodone_cnt iorequest_cnt power queue_type rev scsi_disk:3:0:0:1 scsi_level subsystem type vendor bus device_blocked driver iocounterbits ioerr_cnt model queue_depth rescan scsi_device:3:0:0:1 scsi_generic:sg3 state timeout uevent The first entry is a symlink that points back to the corresponding block device, in this case /dev/sdd: # ls -l /sys/bus/scsi/devices/3\:0\:0\:1/block\:sdd lrwxrwxrwx 1 root root 0 Apr 30 10:06 /sys/bus/scsi/devices/3:0:0:1/block:sdd -> ../../../../../../../../../block/sdd All the symlinks can make navigating sysfs a bit daunting at first but there's a wealth of useful information and knobs to tweak in there. Tools like systool and udevinfo can also help to make it a bit easier to digest.
