You can perform this procedure from system service tools (SST) or dedicated service tools (DST) on the
primary partition.
To display system I/O resources, follow these steps:
1. From the primary partition 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. From the Work With System Partitions menu select option 1 (Display partition information)
4. From the Display Partition Information menu select option 5 (Display system I/O resources).
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.
Once you have arrived at the Display System I/O Resources display, 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 buses).
*IOA (display by I/O adapter (IOA), IOP, and buses).
*DEV (display by device, IOA, IOP, and bus).
The system remembers your last choice so the default displays the level of detail you last selected.
Displaying more system I/O information
You can use the F10 function key to display this information:
v Display serial/part numbers- This view shows the serial and part numbers for the displayed resources
on every logical partition.
v Display logical address- This view shows the logical address for the displayed resources on every
logical partition. For more information on logical address, use the F1 function key on your workstation.
v Display status/ownership information- This view shows the hardware status and ownership
information.
– Hardware status- This field shows the state of the bus and IOP resources. Valid status values are:
Available, Failed, Unavailable, Unknown, and Other. Use the F1 function key on your workstation for
more information on these values.
– Ownership information- This information consists of two fields, Owning Par ID and Ownership
Type. Owning Par ID, shows which logical partition owns which resource. Ownership Type shows
whether each logical partition owns the resource Own bus dedicated or Own bus shared.
v Display using partitions- This field shows which logical partition uses the resource (with or without
ownership).
Displaying logical partition release levels
You can use the Display Partition Release Level display to see which release of the operating system
each logical partition is running.
