HMC will automatically calculate the minimum, desired, and maximum number of Virtual
Processors for logical partition. You may change the virtual processors setting now or later
using Dynamic Logical Partitioning (DLPAR).
1.3.10 Configuring shared uncapped processors for logical partition
The shared processors configuration is stored in the logical partition profile. When the 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 processing units will be assigned to 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 logical partition. To configure shared uncapped processors for the logical partition,
select Shared from the Create Logical Partition Profile - Processors window as shown in
Figure 1-19 on page 22, then select Uncapped from the Advanced Processing Setting as
shown in Figure 1-22.
