Compare CSS / operating system views

You can use the Compare CSS / operating system views function to compare the device definitions of a selected CSS and OS configuration, showing which devices (their numbers and types) are defined to either the CSS or the OS, or both. By using this function you can find out the differences between a hardware (channel subsystem/CSS) and software (operating system/OS) definition in the currently accessed IODF.

When using the Compare CSS / operating system views function, you are offered the possibility of selecting what to print on the Compare CSS / OS Views panel, shown in Figure 1. The Print all data option prints a report of all devices either defined in the CSS or the OS.

The Print different data option prints a report of the devices that differ as follows:

Defined for the CSS, but not for the OS.
Defined for the OS, but not for the CSS.
Defined for both, but of different device type.

If you limit the Compare CSS/OS Views Report for the CSS-side to one partition, it will generate information only for those devices that are attached to the channel paths, that have the limiting partition in the access or candidate list.
