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:
