NOF API Verbs
QUERY_DOWNSTREAM_LU
Primary RUI application. For more information about Primary RUI, see HP-UX SNAplus2 LUA Programmer’s
Guide.
The returned information is structured as determined data (data gathered dynamically during execution, returned
only if the node is active) and defined data (data supplied on DEFINE_DOWNSTREAM_LU). For DLUR-supported
LUs, implicitly defined data is put in place when the downstream LU is activated.
This verb can be used to obtain information about a specific LU, or about multiple LUs, depending on the options
used.
