— 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.
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 Write 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.
■ Buffered Tape Queue Depth sets the Buffered Tape Queue Depth.
Select a setting of 0 through 10 from the drop-down list.
■ Default Map (default: indexed) sets the current mapping mode for the
selected port.
The current map can be set to:
— Port 0 Device Map (HP recommends that this map be used to edit and
assign oncoming hosts.)
— Indexed (default) (HP recommends that this map NOT be edited, even
though the user is able to edit the Indexed map.)
— Auto-assigned contains all the SCSI devices that are attached to the
router.
— SCC
For more information about mapping modes, see Appendix C, " Addressing
Methods and Table Structures ."
For information on changing map settings, see “ Mapping Menu , page 65,”
later in this chapter.
