Troubleshooting
Problem
The following message is issued: EZD0802I TCPIP ENTERPRISE EXTENDER CONNECTION FAILURE ON IP ADDRESS ip_address_1 REASON 0000000C The reason code 0000000C indicates that the IP address requested or used by the caller is not a valid VIPA address for the stack.
Diagnosing The Problem
For VTAM, in the ATCSTR00 member, the following is specified for the IPADDR start option:
IPADDR=ip_address_1
On the IP side, in the TCPIP.PROFILE data set, a single static IPv4 VIPA address is defined:
; Virtual device and link for VIPA
DEVICE VIPD00 VIRTUAL 0
LINK VIPL00 VIRTUAL 0 VIPD00
Also on the IP side, in the TCPIP.PROFILE data set, the following HOME internet addresses are defined:
; HOME INTERNET (IP) ADDRESSES OF EACH LINK IN THE HOST.
HOME
ip_address_3 VIPL00
ip_address_1 LINKSAMEH
Resolving The Problem
If the GROUP definition statement specifies neither IPADDR nor HOSTNAME, VTAM uses the static VIPA address specified on the VTAM IPADDR start option. TCPIP searched for a VIPA in the HOME list matching the IPADDR value - ip_address_1 - specified on the VTAM IPADDR start option.
The IP address specified by VTAM on the IPADDR start option needs to be virtual. That IP address was found to be one of the IP addresses listed on the HOME statement. But that HOME statement associates that IP address with a name - LINKSAMEH - which is not found on the LINK VIPA statement, so the Enterprise Extender connection is rejected as invalid because it specifies an invalid VIPA address.
The HOME statement needs to be modified to associate the IP address specified on the IPADDR start option with a name found on the LINK VIPA statement.
