Displaying Allocated I/O Resources For Logical Partitions - IBM AS/400e Manual

press F10 (Display main storage information) when the Total Processors field shows on the
Display Partition Processing Configuration display.
Interactive Performance Percentage
This field shows you the current and pending amount of interactive performance for each logical
partition. It also shows you the minimum and maximum percentage of interactive performance
available for each logical partition. Only current information shows if SST or DST is running in a
secondary partition. To find this field, press F10 (Display interactive information) when the Main
Storage Size (MB) field shows on the Display Partition Processing Configuration display.
Processor Identifiers
This field shows you which processors you assigned to each logical partition. Only current
information shows if SST or DST is running in a secondary partition. To find this field, press F10
(Display processor identifiers) when the Interactive Performance Percentage field shows on the
Display Partition Processing Configuration display.

Displaying allocated I/O resources for logical partitions

An allocated I/O resource is an input/output (I/O) device that is assigned to a logical partition. You allocate
I/O resources at the I/O processor (IOP) level. In other words, you assign IOPs and all of their devices to
a logical partition.
If you start this display from the primary partition, you get information about the primary partition and all
the secondary partitions. If you start this display from a secondary partition, you get information only for
that secondary partition.
You can print the information in this display by pressing F6.

You can perform this procedure from system service tools (SST) or dedicated service tools (DST).
To display allocated I/O resources, follow these steps:
1. Start SST or DST.
2. From SST select option 5 (Work with system partitions); from DST select option 11 (Work with system
partitions) and press Enter.
3. Select option 1 (Display partition information).
4. Select option 3 (Display allocated I/O resources).
Once you arrive at the Display Allocated I/O Resources display, you can choose to view either one
particular logical partition or all logical partitions.
If you have restarted the primary partition, but not the secondary partitions the display will not be up to
date. You will only see the last buses and IOPs which reported for the secondary partitions. You will not
see IOAs and devices until you start the secondary partitions.
You can choose to view the resources at these levels of detail:
*ALL (everything on the system or allocated to a logical partition).
*BUS (display by system I/O bus).
*IOP (display by IOP and bus).
*IOA (display by I/O adapter (IOA), IOP, and bus).
*DEV (display by device, IOA, IOP, and bus).
