Image catalog for a virtual optical device

 

You can use an optical image catalog to perform an i5/OS^® software upgrade, install PTFs (fixes), or install single licensed programs that you receive on CD-ROM or optical media. You can also use a tape image catalog and a virtual tape device to install PTFs or to install single licensed programs. You cannot, however, use a virtual tape device to install or upgrade to an i5/OS release.

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 i5/OS 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 optical devices do not support the following:

  • Write operations (prior to V5R3)

  • The LODRUN command using multiple media.

  • Changing a primary language from secondary language media.

• To perform an installation using image catalogs, have at least 1074 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.
