LUN Mapping
The method of LUN mapping differs between VLS firmware versions 3.x and 2.x.
LUN Mapping (v3.x)
LUN mapping is used to present only a subset of the VLS virtual devices to a host. If LUN mapping is
enabled, the VLS prevents all hosts connected to the VLS through the SAN from viewing any virtual
devices until they are explicitly mapped to the host. By disabling LUN mapping, the VLS allows all
hosts connected to the VLS to access all virtual devices configured on the VLS. By default, LUN mapping
is disabled. The setting you choose will apply to every new host that you add to the VLS. See
"Setting the Default LUN
Setting the Default LUN Mapping
You can set a global default to disable or enable LUN mapping. The setting you choose will apply
to every new host that you add to the VLS.
