Changing Logical Partition Processors - IBM AS/400e Manual

Note: If you are also changing processors or interactive performance, do not press Enter after the next
step. You can wait until you change interactive performance and main storage before pressing
Enter. This will save you time.
9. At the confirmation display, press Enter to confirm your choice.
10. Restart the entire system to activate the changes.

Changing logical partition processors

This page describes how to add and remove processors on a logical partition. If you have not physically
added more processors to the system or have processors available, you must remove processors from
one logical partition then add them to another. You can add and remove as many processors from a
logical partition as you need as long as you remember these rules:
v Each logical partition must have at least one processor.
v The sum of the processors in all of the logical partitions cannot exceed the number of processors in the
system. For example, you cannot have three processors in the primary partition, and two processors a
secondary partition if your system only has four processors.
Notes:
1. To activate the changes from adding and removing processors on secondary partitions you need to
restart the secondary partitions.
2. To activate changes to processors on the primary partition you need to restart the system.
3. If you are also changing the logical partition's main storage or interactive performance, wait until you
have made all of your changes before you restart. This will save you time.
You can perform this procedure from dedicated service tools (DST).
To change partition processors follow these steps:
1. Start DST.
2. From DST select option 11 (Work with system partitions) and press Enter.
3. Select option 3 (Work with partition configuration).
4. Use your cursor to select the logical partition you want to change.
5. Select option 2 (Change partition processing resources) and press Enter. The Change Partition
Processing Resources display appears.
6. Use the cursor to select New number of processors.
7. If you want to set limits, press F9.
8. Type the new number of processors and press Enter.
Note: If you are also changing interactive performance or main storage, do not press Enter after the next
step. You can wait until you change interactive performance and main storage before pressing
Enter. This will save you time.
9. At the confirmation display, press Enter to confirm your choice.
