Chapter 3. HMC overview and planning 67
Once the partition is created and the OS is loaded, hardware assigned to that partition can be
viewed from hardware management programs.
The column labelled Pool ID designates the I/O pool that the card slot is assigned to. The I/O
pools are used in conjunction with clustering and allow systems in the same cluster to pool
their I/O in a common pool. See Figure 3-25.
Figure 3-25 Hypervisor runs under the partitions
Important: When planning to partition a new system that has no operating system on it, or
when adding new hardware to an existing system, this new hardware will initially only be
seen by the HMC, and the IO resources pane will only show a view of the hardware down
to the card slot positions.
Therefore, if you need a more comprehensive view of the I/O resources showing where the
disk drives, tape drives, CDs, or DVDs are, prior to loading an operating system, then you
may have to consider drawing a diagram of the system showing the locations.
Our suggestion is to always use the LVT and supplement it with a sketch of the system.
You could photocopy out the system layouts from the i5 System Builder. Fill in the
locations of the devices and indicate to which partition they are allocated.
