If you have at least one ethernet NIC, you have at least one globally unique MAC address, which is 6 bytes of uniqueness to draw from. I'm sure there are countless other possibilities. I think the SAN issue is way overstated. Sure it's real, but so are SHA conflicts in the kernel GIT repository. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
