Microprocessors in a partition

Microprocessors can be assigned to an LPAR.

Assigned microprocessors
To view a list of microprocessors that are assigned to an LPAR, select the Managed System (CEC) object on the HMC and view its properties.
Impact of disabling microprocessors
When disabling microprocessors on a POWER4-based system with an MCM, there is still routing of control flow and memory accessibility through the existing microprocessors on the overall system. This might impact overall workload performance.
