Mixed shared and dedicated PR/SM partitions

As with configurations in which all PR/SM partitions share available CPs, those shared partitions within a mixed configuration also support concurrent CP upgrade. CPs are added, without disruption to any of the partitions, to the pool of physical cores shared among the shared CP LPs. In addition, partitions configured with dedicated CPs in a mixed environment can add new CP capacity while both the shared CP partitions and the dedicated CP partition run uninterrupted. To prepare for this ability, in the following example simply define Partition 3 as a three-way dedicated partition with two initial logical cores and one reserved logical core (see Figure 1 for a similar example). The reserved logical core is offline automatically at the time of partition activation. At the time of the concurrent CP upgrade, the SCP operator command can be used in the dedicated partition to configure a third CP online to the dedicated partition without interruption to any logical partition.
