Fibre Channel Port Configuration - HP N1200 - StorageWorks Network Storage Router User's And Service Manual

Fibre Channel port configuration

When the Fibre Channel port is selected in Ports menu, the Fibre Channel Configuration screen is
displayed (see
Figure 22 Fibre Channel port 0 configuration settings screen
Fibre Channel port settings:
• Link Status indicates the port link status.
• 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 network storage router to bypass the loop negotiation and
come up as a fabric only. If the network storage 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 network storage router discovers
new Fibre Channel devices.
Discovery mode settings:
• Auto Discovery on Reboot allows the network storage 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.
