Where are the standalone Repositories for use with systems that DO NOT have internet access?
One answer
What documents have you read? If it mentions about IBM Installation Manager, it should also mention downloading the Installation Manager repository. Basically, you need to download the first file under the "IBM Installation Manager Repositories" section in the below download page, and then move this file to your server.
