Error Message :
U00011605 The combination of hardware 'xx/xx/xxx' and software 'xxx' version 'xx' ('000000016') is not supported
AS400 agents that ran just fine in a previous version of the Automation Engine refuse to start. The above error message appears in the agent's logs.
Investigation
The same host has 2 AS400 agents installed. One runs on version 10, and the other runs on v12.
Results
Expected: Because both agents run on the same host, the agent's characteristics should not differ: OS400 hardware and software version should be recognized similarly in version 10 and version 12 of the Automation Engine.
Actual : The hardware is recognized differently in the agent's logs.
