Unfortunately, dmidecode didn't provide any useful info (for this purpose anyway), although is is quite interesting ! ;-) I can get what I need using cat /proc/pci and ifconfig, since IRQ is a common field between the two and thus I can make the link. However since there's 50+ nics involved here across the whole cluster, I was hoping for a single command I could issue from the management node that would provide both key bits of info (ie pci slot and eth* details) Looks like it's back to the printouts with a pen ! ;-( (I'm sure I could script something up with awk and so forth, but by the time I'd done that, it would have been quicker to do it manually for 50 nics. Maybe for 250 or more, the script would be worthwhile) Thanks anyway Andrew
