Global Automap and Unmasking Overview
Global Automap All Targets defaults to enabled, to allow the driver to detect all
Fibre Channel devices attached to the HBAs. If Global Automap All Targets is
disabled, the driver detects Fibre Channel devices attached to the HBA, and does
not pass them to the operating system unless they are already persistently bound.
Global Automap All LUNs defaults to enabled and assigns an operating system
LUN ID to a Fibre Channel LUN ID for all LUNs behind the targets in your SAN.
LUN mapping can also be enabled and disabled at the target level. Global
automapping of LUNs is different from persistent binding. Global LUN
automapping does not concern itself with the SCSI ID or SCSI Bus. This is
because the global LUN mapping stays the same for the target when the system is
rebooted.
Globally Unmask All LUNs defaults to enabled, to allow the operating system to
see all LUNS behind targets. If Globally Unmask All LUNS is set to disabled
and you want the operating system to see all LUNS behind a specific target, you
must set unmasking at the target level.
Prerequisites

AB466A and AB467A PCI-X Host Bus Adapters for 64-Bit Windows Systems Installation Guide
Installed SCSI Miniport driver
Installed LightPulse Utility
A target device with LUNs that have been properly configured
LUN Automap enabled and LUN Unmasking disabled on the LUN Mapping
window:
— If LUN Automap is enabled for the target, you can map each LUN
individually.
— Unless LUNs were previously mapped, if LUN Automap is disabled for
the target, no LUNs will be mapped when you reboot the system.
— If LUN Unmasking is disabled for the target, the HBA can see all LUNS
behind a specific target.
