Setting priority for ports: one-to-one connections

Prioritized ports are ports on which processing has high priority, and non-prioritized ports are ports on which processing has lower priority. Specify a port that connects to a high-priority host bus adapter as a prioritized port. Specify a port that connects to a lower-priority host bus adapter as a non-prioritized port.
