Caution: If the following configuration settings are incorrectly set, processing
difficulties may occur. Before changing these settings, evaluate the need for
the change and verify the desired setting. HP recommends backing up the
router configuration to an external file before making changes to these
settings.
■ Port Name Low sets a new value for the World Wide Port Name High.
(Service Mode - Restricted Access)
■ Port Mode (default: N_Port) sets the port mode.
Port Mode settings:
— Auto Sense: In this mode, the Fibre Channel port tries to negotiate as a
loop. If it is not successful, then the Fibre Channel port negotiates as a
fabric. If the port comes up as a loop, it then determines whether it is on a
private or public loop.
— N_Port: (default) This mode allows the router to bypass the loop
negotiation and come up as a fabric only. If the router is on a loop, and
N_Port mode is selected, an error in communication may occur.
■ Use Hard AL_PA enables or disables Hard AL_PA usage.
■ Hard AL_PA Settings displays the AL_PA Lookup Table.
Use the table to find the node number. This unique one-byte valid value
(derived from an Arbitrated Loop Topology defined in ANSI specification
FC_AL version 4.5) is used for the Fibre Channel configuration.
■ Discovery Mode (default: Manual Discovery Only) determines how the
router will discover new Fibre Channel devices.
Discovery mode settings:
— Auto Discovery on Reboot Events allows the router to automatically
discover all Fibre Channel devices when rebooted or when link-up events
occur, such as connecting cables or rebooting network hubs.
— Both the ports and the devices behind the ports are discovered on all
subsequent link-up events.
— Auto Discovery on Link Up Events allows the router to automatically
discover all Fibre Channel devices when rebooted or when link-up events
occur, such as connecting cables or rebooting network hubs.
— Both the ports and the devices behind the ports are discovered for the first
link-up event. Subsequent link-up events will only discover the ports and
not the devices behind the ports.
