Install Linux from CD-ROM images in the integrated file system

 

Most Linux distributors provide ISO CD-ROM images that can be downloaded from their Web site. If your distributor has multiple physical CDs for the install action of Linux, ISO file images are a convenient way to install from a directory on your iSeries™ server.

The ISO images used to install Linux will have one of these descriptions:

• Unloaded: This option allows you to unload an optical image from the virtual optical device. Only images that have a status of Loaded can be unloaded.

• Loaded: This option allows you to load an optical image into the virtual optical device. Only images that have a status of unloaded can be loaded.

• Mount: This option allows you to mount an optical image into the virtual optical device and activate it. Only images that have a status of loaded can be mounted.
