Create an image catalog
The Create Image Catalog (CRTIMGCLG) command associates an image catalog with a target directory where the optical image files are loaded. Enter the following command:
```
CRTIMGCLG IMGCLG(catalog-name) DIR(catalog-path) CRTDIR(*YES) TEXT(text-description)
```
Add an image catalog entry
Add an image catalog entry for each physical media that you have. Repeat this step for each volume of media. Add the images in the same order as if you were going to install from them. Start with the first media in the list and continue until all the media are loaded.
Enter the following to add an image catalog entry to an image catalog from a physical optical media device named OPTxx:
```
ADDIMGCLGE IMGCLG(catalog-name) FROMDEV(OPTxx) TOFILE(file-name) TEXT(text-description)
```
Note: To generate a name for the TOFILE parameter, specify *GEN. To generate a text description from the media, specify *GEN.
You now have virtual images in the catalog path that you specified on the CRTIMGCLG command.
