NOF API Verbs (ACTIVATE_SESSION to OPEN_FILE)
DEFINE_DOWNSTREAM_LU
Chapter 3 213
DEFINE_DOWNSTREAM_LU
DEFINE_DOWNSTREAM_LU defines a new downstream LU, and maps
it to an upstream host LU or LU pool (defined using
DEFINE_LU_0_TO_3 or DEFINE_LU_POOL). This allows the
downstream LU to access the host computer using the PU concentration
feature of SNAplus2. This verb cannot be used to modify an existing
downstream LU.
If you need to activate a downstream LU that is already defined (for
example, because the downstream workstation has just been activated),
issue the DEFINE_DOWNSTREAM_LU verb for that LU.
