Unassigning a Cell from a Partition
When a cell is unassigned from a partition in a system with Instant
Capacity, the number of intended active processors in the partition
decreases only if the number of processors being removed with the cell is
greater than the number of unlicensed processors in the partition. In the
following example of a single partition system with 3 cells, the number of
intended active processors remains the same because the number of
processors with the removed cell (4) does not exceed the total number of
unlicensed processors in the partition (6).
When Cell 3 is unassigned from the partition, the number of intended
active processors for the partition remains at 6. When the partition is
rebooted, a total of 6 processors are activated. Cell 3 becomes an
unassigned cell, and in order to be in compliance, all 4 processors in Cell
3 are unlicensed (Instant Capacity) processors.
