Messages IST1110I and IST1246I received during CP-CP session activation failure

Problem statement: Attempt to activate CP-CP session pair between end node and network node fails after activation of CP-capable link.
Common symptoms: Activation of new CP-CP session pair with network node specified in message IST1110I is terminated. Message IST1110I is displayed along with message IST1246I at the end node.
Probable cause: While in the process of bringing up the contention winner CP-CP session, the end node determined that the network node named in IST1110I is not explicitly named in the end node's network node server list and that there is no nameless entry in the network node server list.
User response: Either perform an operator activation of the CP-CP session by entering V NET,ACT,ID=adjacent_cpname at the end node or modify the network node server list to include either an explicit entry for the required network node or a nameless entry.
