I/O Adapters

This area lists the I/O slots that meet the selected filter criteria. The following information displays for each I/O slot.

Slot

This column displays the slot number that identfies the location of the I/O slot within the system unit or expansion unit.

Bus

This column displays the bus on which the I/O slot is located.

FRU

This column displays the Field Replaceable Unit (FRU) number for the I/O device in the I/O slot.

Owner

This column displays the name of the logical partition that currently owns the I/O slot.

Description

This column contains description of the I/O device in the I/O slot. If the I/O device is an I/O processor (IOP), this description is either PCI I/O Processor or I/O Processor.

If the slot is empty, this description is Empty slot.

Otherwise, the wizard uses the first description it finds in the following hierarchy.

• Description of the custom card identification number (CCIN)
• Description of the feature code
• Description of the Peripheral Component Interface (PCI) class code
• Unknown

The managed system updates the description only when the physical I/O device belongs to a running logical partition. This information might not be up to date if you remove the physical I/O device from the running logical partition or shut down the logical partition to which the physical I/O device belongs.
