Configuring Tape Device Extension
This option, referred to as the Report LUNs mode, determines 
how LUN 0 is represented on this interface. It is used by initiators 
to determine the LUN inventory of certain devices (typically 
RAIDs). The Report LUNs command is processed locally and 
reflects all configured or discovered devices.  
14. Click on the Host tab.
15. Enter the source WWN in the Source WWN field for each LUN 
that needs filtering applied.
See the example shown in Figure 8-3 and Table 8-2 (page -5) for 
the source of this WWN.
Emulate —
LUN 0 is statically configured as a local McDATA 
controller. This mode results in the Report LUNs 
command being intercepted and an inventory being 
generated based on the UltraNet configuration. 
When this occurs, the initiator will follow up with the 
INQUIRY commands to all the devices included in 
the UltraNet configuration. Results of Emulate mode 
will vary depending upon the behavior of the 
initiator to the emulated inventory. This mode will 
not work for all configurations.
Passthru —
LUN 0 is an actual remote device (either discovered 
or configured). This mode allows the Report LUNs 
command and response to flow through the 
McDATA network unaltered. Only the LUNs in the 
Report LUNs reply will be known to the initiator.
Emulate mode is the default.
