Display system bus resources

This option is available only on the Logical Hardware Resources display.

From the Logical Hardware Resources display

The System bus resources option is available only on the Logical Hardware Resources display. For details, see Logical hardware resources. From the Logical Hardware Resources on System Bus display, you can perform the following:

Perform the following I/O debug functions:
- Read/write I/O processor data. For details, see Debug the resource.
- Dump I/O processor data. For details, see Performing an IOP dump.
- Reset I/O processor. For details, see Debug the resource.
- IPL I/O processor. For details, see Debug the resource.
- Enable I/O processor IPL. For details, see Debug the resource.
- Disable I/O processor IPL. For details, see Debug the resource.

The Logical Hardware Resources on System Bus display shows the logical hardware resources in levels, beginning with the system bus. For example, a system bus might have one or more IOPs attached, an IOP might have an associated controller, or a controller might have an associated device. All associated first level logical hardware resources are shown. Option nine allows you to see the resources that are associated with each I/O processor.

Logical hardware resources on system bus (frames with a PCI system bus)

For frames with a PCI system bus, the Logical Hardware Resources on System Bus display shows the logical hardware resources in levels, beginning with the fabric I/O bridge. A fabric I/O bridge has one or more bus expansion adapters. A bus expansion adapter has one system bus. A system bus has one or more multi-adapter bridges. A multi-adapter bridge might control one or more IOPs.
