Standing up a Snorcle x4540 storage server. Nice Cisco 4849 switches, and Solaris 10U9. But wait, the stupid NVidia NGE driver autonegotiates 100/Half to the Gigabit Network switch. Whiskey-Tango-Foxtrot. My goodness. Years and years of hardware development and standards and two name brand devices can't figure it out. Great.
Start pounding on the various incarnations of the adv_*_cap flags with ndd to see if I can get a clue why it's doing what it's doing. Big chart brewing, and I'm probably gonna have to talk to some guy in a foreign language to see if this problem has a known resolution, or if it's gonna take hammering it for a couple of hours to find the 2^12 combinations that gets me 1000Mbs. At least the network guy is a charm to work with so I know we'll figure it out the hard way.
