Messages IST1110I, IST1112I, IST1765I, and IST1766I received during CP-CP session activation failure

Problem statement: End node operator's attempt to activate CP-CP session pair by activating adjacent network node fails and messages IST1110I, IST1112I, IST1765I, IST1766I, and IST314I are issued at the end node.
Common symptoms: Activation of new CP-CP session pair with adjacent CP specified in message IST1110I is terminated. Messages IST1110I, IST1112I, IST1765I, IST1766I, and IST314I are displayed.
Probable cause: While attempting to activate a contention winner CP-CP session with the network node specified in message IST1110I, the end node determined that it already had an active CP-CP session pair with a different network node. If an end node already has a network node server, it does not accept a new CP-CP session with another network node.
User response: Before attempting to activate a CP-CP session pair between an end node and a network node, enter the D NET,NETSRVR,SCOPE=ONLY command at the end node to verify that no CP-CP sessions with a network node exist.
