Several error conditions to the IBM® zAware server location can occur for a z/OS® log stream client.
Check the IBM zAware server level and location to ensure it is installed and running on the PR/SM™ logical partition (LPAR) where expected. Ensure the IXGCNFxx parmlib member ZAI SERVER and PORT information correctly identifies the IBM zAware server location.
Confirm that the communication is allowed (such as sockets connections being allowed over any firewall, and the appropriate routers in the path support the IP format address type).
