This article was previously published under Q164592 SYMPTOMS
Microsoft SNA Server versions 2.11 and later provide support for
Dynamically Defined Dependent LUs (DDDLU) for 3270 LUs. However, DDDLU
support for LUA LUs is not provided in SNA Server.

161492 INFO: LU Session Activation Using Dynamically Defined Dependent LUs
CAUSE
When DDDLU support was originally added to SNA Server, DDDLU support was
only implemented for 3270 LUs.
RESOLUTION
An update to SNA Server 3.0 is available. It provides DDDLU support for
LUA LUs. By default, DDDLU support for LUA LUs is disabled. To enable this
support, the following registry entry must be set to specify the Model
Number to be requested by SNA Server when an LUA LU is dynamically
activated.
HKEY_LOCAL_MACHINE
\SYSTEM
\CurrentControlSet
\Services
\SnaServr
\Parameters
\LUADDDLUModel:REGDWORD: <Model Number>
Model Number can be 1 through 5 to correspond to supported
3270 Model Numbers.
The following files were updated to add this support:
<snaroot>\system\snaservr.exe
<snaroot>\system\trcservr.exe (used for debugging purposes only)
STATUS
Microsoft has confirmed this to be a problem in SNA Server versions 2.11,
2.11 SP1, and 3.0.
This problem was corrected in the latest Microsoft SNA Server 3.0 U.S.
Service Pack. For information on obtaining the service pack, query on
