Issue/Introduction

We just implemented z/OS V2.3 on a test LPAR. We started getting the following messages:
CAS9899E Task nn Error: Unable to determine IP address for sysidA
CAS9899E Task nn Error: Unable to determine IP address for sysidB 
CAS9899E Task nn Error: Unable to determine IP address for sysidC
CAS9899E Task nn Error: Unable to determine IP address for sysidD
CAS9899E Task nn Error: Unable to determine IP address for sysidE 
CAS9899E Task nn Error: Unable to determine IP address for sysidF 
CAS9899E Task nn Error: Unable to determine IP address for sysidG.

These messages were repeated several times following error messages such as:
CAS9PSPM- getaddrinfo failed resolving 'host name', errno = 1114
getaddrinfo error - RC: 1 (EDC9501I The name does not resolve for the supplied parameters.)
CAS9850I - CCI TCP/IP Host Name = 'host name'
CAS9850I - Port = port number, Addr = 0.0.0.0 

Environment

• z/OS 2.3
• Common Services r14.1 CCI component

Cause

Unix wasn't completely set up before the new operating system was brought up  

Resolution

Set up Unix prior to implementing the new z/OS operating system
