This article was previously published under Q276470 SYMPTOMS
SNA Server may fail to dynamically activate a logical unit (LU), through the host Dynamic Definition of Dependent LUs (DDDLUs), after the physical unit (PU) on the mainframe has been recycled. The result is that the LUs that are defined on this host connection may show a "pending" status when viewed in SNA Server Manager after an application tries to connect to the LUs. The application that is trying to reconnect to the LU at this point cannot get an active session to the host.
The same problem may occur when the host connection is stopped and restarted through SNA Server Manager.
CAUSE
The SNA Server service doesn't check whether the LU-System Services Control Point (SSCP) session is down before it tries to send the Network Management Vector Table (NMVT) request to deactivate the session when an application disconnects. This results in the SNA Server not sending an NMVT request to activate the LU when an application tries to reconnect to an available LU.
NOTE: The LU will be available again once the PU is activated on the host or the connection is restarted on SNA Server.
