Watch FC Card Utilization
With the watch fc-card command, you can run a command that continuously
updates the Fibre Channel card utilization over a period of time. The watch
fc-card command (and watch fc-cards) will intermittently poll the Fibre
Channel card and display the updated, real-time statistics automatically. The polling
window is fixed (not configurable), and the command is useful for seeing how the
card is being used as well as viewing trends in usage over time.
Display continuous FC card utilization for a single card by issuing the watch
fc-card command. For all FC cards, use the watch fc-cards command.
Set FC Port Attributes
Each FC port is controlled by a back-end logic chip, and a set of attributes and
properties can be controlled from the command line. Some of the attributes are
displayed only when using the -detail argument for show fc port:
