New Partition Creation and Instant Capacity
You can assign a cell to an existing partition even if the cell contains
unlicensed processors. In this case, it can be verified that the partition
has valid Instant Capacity software installed, and that the partition is
running an operating system capable of activating and deactivating
processors.
However, at the time a new partition is created, these verifications are
not possible; therefore, the Instant Capacity software does not allow the
partition to be created unless it contains only licensed components. That
is, new partition creation fails if any of the cell boards contain unlicensed
components.
