Hi Mark, I don't agree. There are 2 steps in this discovery process. For the first step for target ports, it is exactly as I described early. The tool only uses what is available in /sys. There is no interaction with the nameserver unless the device is being brought online.
For the second step for LUNs, the tool does make a good effort. It sends report luns to a couple of well-know LUNs. I liked the older san_disc that shipped with the earlier distros. It was tedious to use, but it always queried the SAN.
