Enter minimum, desired, and maximum processors for the logical partition. Figure 1-18
shows an example of minimum, desired, and maximum processors for the dedicated logical
partition. Adjust these values with the logical partition workload.

1.3.9 Configuring shared capped processors for logical partition
The shared processors configuration is stored in the logical partition profile. When the shared
logical partition is started, a number of processing units assigned to the logical partition will be
based on the shared processors configuration in the logical partition profile. These
processing units are available from the shared processors pool. When started, the logical
partition will be assigned the desired amount of processing units. If the desired amount of
processing units is not available from the shared processors pool, the minimum number of
processing units will be assigned to the logical partitions. If no processing units are available
from the shared processors pool, the logical partition cannot be activated.
At the first time the logical partition is created, you have to define the processor configuration
for the shared logical partition. You have to decide if you will use shared capped processors
or shared uncapped processors mode. To configure shared capped processors for the logical
partition, select Shared from the Create Logical Partition Profile - Processors window, as
shown in Figure 1-19.
