You can use an optical image catalog to perform
a 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 server 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, you must
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.
