System information

66 Logical Partitions on System i5
System Properties - IO resources
When expanded, Figure 3-24 shows the I/O resources across the managed system.
The example shown has two units or frames, a 5094 expansion tower, and a 5088 IO
expansion tower. Unit 5094 contains bus 23 to 25. We have not shown the buses in the other
unit. The cards in the card slots are shown as the generic card types. For example, card slot
C05 in bus 25 contains a PCI I/O controller and the type indicates that this is a #2844 card.
Note that the slots/cards are unassigned, as they are not currently being used by a partition.
Figure 3-24 Managed system - I/O slot properties
The Hypervisor (Figure 3-25) is code that runs on the managed system and allows the three
operating systems (AIX, i5/OS, and Linux) to run on the one physical system. The Hypervisor
will only report the Custom Card Identification Number (CCIN), if it can recognize the card.
Certain cards need a driver loaded into the card for it to report the CCIN number, and hence
they may not report it to the Hypervisor. For i5/OS partitions, a rack configuration listing will
still be able to be run from the partition to display the I/O resources and their CCIN numbers.
An example of a CCIN number is 2849, which is the CCIN for a 10/100 ethernet card. This is
important to note for that partition.
The I/O slot view will only drill down to the card slot positions. It will not show any I/O attached
to the cards in the slots, and hence will not show any disk drives, tapes drives, CDs, or DVDs.
