• Discovery Mode—(default: auto discovery on reboot events) determines how the
router will discover new Fibre Channel devices.
Discovery Mode settings:
— Auto Discovery on Reboot Events—(default) 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—sets discovery of new devices to only occur after
the user selects the Discovery option from the Main Menu or when a
Registered State Change Notification (RSCN) is received from a fabric.
NOTE: SCSI devices attached to a Fibre Channel must be mapped as sequential Fibre
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.
• 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. Compaq 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.
• Buffered Tape Queue Depth—sets the Buffered Tape Queue Depth.
Select a setting of 0 through 10 from the drop-down list.
