Issue/Introduction

Completed the setup of ENF and CCI on a set of LPARs in a SYSPLEX.  The LPARs are named - M102, M202, and M302.

The setup included both VTAM and TCP/IP connections between the systems.

After starting everything up, on one system (M102) I issued command: F CCITCPGW,PING,M302

F CCITCPGW,PING,M302                              
CAS9899I - ENTERED COMMAND: PING,M302             
CAS9899I SYSID NOT FOUND        

  • Why does the command return this message?

 

Following are some VTAM and TCPIP displays showing connectivity:

A STATUS command issued on M102 shows the following:

CAS9850I - CCI TCP/IP Protocol Driver TCPIPGW  Starting
CAS9850I - CCI Sysid Name = M102

  • Does the SYSID have to be unique in the parm NODE(LU0) and NODE(TCPIPGW) or can it be the same even though you have both LU0 and TCPIP active?
  • Are these persistent connections or only connect when required?
 

Environment

Release : 15.0
Component : CAICCI-MVS

Cause

Multiple NODE statements for the same remote systems defining different types of connectivity.

The reason for the "SYSID NOT FOUND" message in response to a CCITCPGW PING command is because there was not an active connection via the TCPIPGW protocol. At the time the active connection was via VTAM (LU0).

Resolution

Define only one NODE statement should be defined for a remote system to establish connectivity.

If multiple NODE statements for the same remote system are defined, only one will establish a connection. Generally the one that connects first. VTAM will usually win in this situation as the TCPIP environment generally is not active before VTAM.

The CCI SYSID has to be unique on each LPAR.

The VTAM and TCPIPGW connections are persistent.
