Image catalog for a virtual device
You can use either an optical image catalog or a tape image catalog to perform an IBM® i software upgrade, install PTFs (fixes), or install single licensed programs.
An image catalog is an object on the system that contains optical images. Each catalog is associated with one user-specified integrated file system directory. The system-recognized identifier for the object type is *IMGCLG.
Image catalog requirements:
- An image catalog upgrade works like a D-mode IPL without a console during the installation of Licensed Internal Code. Reference codes are used to display the status.
- Installations done by using image catalogs require an IBM i control language (CL) command line to initiate the installation.
- An installation cannot be performed if an independent auxiliary storage pool (ASP) is accessible. Image files cannot reside in an independent ASP.
- Virtual media devices do not support the following:
- Write operations (before V5R3)
- The LODRUN command using multiple media.
- Changing a primary language from secondary language media.
- To perform an installation using image catalogs, you must have at least 2000 MB of free storage on the load-source disk unit. Preparing to upgrade or replace software using an image catalog describes how to calculate storage requirements and free up space in the load-source disk unit for an image catalog. Cleaning up disk storage space describes other general considerations on how to free up space in the load-source disk unit.
