Note:
Channel LUNs starting at LUN number 00. Skipping LUN numbers is not recommended
when mapping Fibre Channel LUNs because Fibre Channel Discovery stops the
discovery process whenever an empty LUN position is found.
Network Storage Router N1200 User Guide
Discovery Mode (default: manual discovery on reboot events) 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.
— Manual Discovery Only (default) sets discovery of new devices to occur
only after the user selects the Discovery option from the Main Menu or
when a Registered State Change Notification (RSCN) is received from a
fabric.
SCSI devices attached to a Fibre Channel must be mapped as sequential Fibre
Buffered Tape Writes (default: enabled) enables or disables the Buffered
Tape Writes option.
Caution: If this configuration setting is incorrectly set, processing difficulties
may occur. Before changing this setting, 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 this setting.
When enabled, to enhance performance, Buffered Tape Writes return status
on consecutive write commands prior to the tape device receiving data.
