Why is our VTAM CP-CP session activation failing with error messages IST1110I, IST1246I, and IST1280I?

Question & Answer

Question

Our attempt to activate a CP-CP session pair between a VTAM end node and a VTAM network node failed. These error messages were issued on the end node:

IST1110I ACTIVATION OF CP-CP SESSION WITH cpname FAILED

IST1246I ADJACENT CP NOT DEFINED IN CURRENT NETWORK NODE SERVER LIST

IST1280I SESSION TYPE = CONLOSER - SENSE = 80050000

Answer

While in the process of bringing up the conloser 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 (NNSL) and that there is no nameless entry in the network node server list (NNSL).

Either perform an operator-activation of the CP-CP session by issuing the command V NET,ACT,ID=adjacent_cp_name at the end node or modify the network node server list to include either an explicit entry for the desired network node or a nameless entry.
