You must distribute an ISO file beforehand to all servers that will use it (see Adding an ISO File to a Server). When the distribution is complete, you must select the ISO file to use in an upgrade before beginning the process. If you have multiple ISO files available for an upgrade (for example, if you have a major release and an update release, or an update release and a patch), you can select which one to use. If you have multiple clusters to upgrade, you only have to select the ISO file for the CMP system.
To select an ISO:The ISO is selected for upgrade. The data in the Up to date column changes from n/a to either Y (which means that the server is running up-to-date software) or N (which means that the server needs upgrading).
