McDATA UltraNet Edge 3000 User Guide
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.
