APAR status
Closed as fixed if next.
Error description
The following messages are received when sessions are routed across an EE connection network VRN: IST1139I CONNOUT FAILED - SENSE FFC80004 IST1903I FAILURE OVER VRN vrnname TO CP cpname This occurs because the IP address associated with the VRN that was selected for the session route is identical to the IP address already being used by an existing VRN connection. New diagnostic messages are needed to identify the VRN and IP addresses associated with the existing connection.
Local fix
specify different local static VIPA addresses for the each EE VRN.
Problem summary
**************************************************************** * USERS AFFECTED: All who define multiple Enterprise Extender * * virtual routing nodes (VRNs). * **************************************************************** * PROBLEM DESCRIPTION: The following messages are received * * when sessions are routed across an EE * * connection network VRN: * * IST1139I CONNOUT FAILED - SENSE * * FFC80004 * * IST1903I FAILURE OVER VRN vrnname * * TO CP cpname. * **************************************************************** * RECOMMENDATION: * **************************************************************** In this case, the VTAM start option, IPADDR, was specified. Two VRNs were defined in the EE XCA major node without the IPADDR operand on the GROUP statement. This caused both VRNs to default to the IPADDR value from the start option. When a line under the GROUP defining a VRN is activated, the VRN itself is created and is assigned an identifier that consists of the local SAP address and IPADDR for the VRN. Since the SAP and IPADDR were the same for both VRNs, the activation of a line under the second GROUP created a VRN with a duplicate identifier. Similar definitions were duplicated on remote systems. Later, when sessions were routed across either VRN, they failed with the following: 1. Message IST1139I CONNOUT FAILED - SENSE FFC80004 was issued, indicating that the addressing keys (local/remote SAP/IPADDR pairs) duplicate those of a preexisting connection. 2. Message IST1903I FAILURE OVER vrnname TO CP cpname was issued to identify the VRN attempting to use the duplicate SAP/IPADDR pairs.
Problem conclusion
Temporary fix
Comments
The following change(s) will be included in z/OS Communications Server V2R1: Modules ISTAUCOR and ISTAUCAM and macros ISTAUCPL and IPTADDRS will be changed to issue additional messages when message IST1139I CONNOUT FAILED - SENSE FFC80004 occurs on an attempt to set up a session over an EE VRN. This sense is issued when duplicate local/remote SAP/IPADDR pairs are detected. Existing message IST1680I will now be issued to identify the local and remote IP addresses and new messages will be added to identify the duplicate EE VRN name. Existing message IST1903I currently identifies the VRN attempting to use the duplicate SAP/IPADDR pairs. The following will also be changed to add message support: ISTCFCMM, ISTINCNO, ISTCFCML, ISTVTMEU, and MSG2350. This APAR is being closed FIN (Fixed If Next) with concurrence from the submitting customer. This means that a fix to this APAR is expected be delivered from IBM in a release(if any) to be available within the next 36 months.
