Lun device mapping

[Jason DePaul]

what's up everyone. I am having an issue that I hope you can help with. I need determine which LUN (from an external fibre array) is mounted to a specific device in RHEL 3.

/proc/scsi/scsi shows me the available luns
fdisk -l shows me the physical volumes/devices

but nowhere can I see the correlation between the both of the them

if /dev/sdd1 is using LUN 4, then I want to know that

Any help would be greatly appreciated.

Peace
JD
