DEFINE_DOWNSTREAM_LU_RANGE
Chapter 3 219
DEFINE_DOWNSTREAM_LU_RANGE
DEFINE_DOWNSTREAM_LU_RANGE defines a new range of
downstream LUs, and maps them to an upstream host LU or LU pool
(defined using DEFINE_LU_0_TO_3 or DEFINE_LU_POOL). This
allows the downstream LUs to access the host computer using the PU
concentration feature of SNAplus2. This verb cannot be used to modify
existing downstream LUs.
The supplied parameters to this verb include a base name for the new
LUs and the range of NAU addresses. The new LU names are generated
by combining the base name with the NAU addresses. For example, a
base name of LUNME combined with a NAU range of 11 to 14 would
define the LUs LUNME011, LUNME012, LUNME013 and LUNME014.
