Cisco UCS VIF paths enter error disabled until first use.

This produces warning events F0207, F0479, F0283. These errors clear once each port has been fully initialized by an appropriate driver - ESXi or Debian Squeeze installer images are an easy way to take care of this. Shame the docs make no mention of this and point only to failed uplinks and un-acknowledged hardware.
