Chapter 9. DDDLU enhancement
DDDLU is an acronym for Dynamic Definition of Dependent LUs. It is
sometimes referred to as Self-Defining Dependent LUs (SDDLU). This
feature allows dependent LU definitions to be dynamically created on the host
by VTAM when they are needed.
If the host VTAM is DDDLU capable, it will send information to CS/AIX when
the link station activates to indicate that the host supports DDDLU. When a
host LU is needed, CS/AIX sends in a Reply Product Set ID (PSID) Network
Management Vector Transport (NMVT) with the required information VTAM
needs to dynamically define the dependent LU.
