An administrator configured IVE in their Power 570 with a multicore scaling (MCS) value of
8. After some time they decided to add more LPARs to the system. To allow more logical
ports for the new LPARs, the administrator changed the MCS value in the HMC to 4. When
configuring the new LPAR profiles, the administrator does not see the extra ports. Which of
the following is the most likely reason?

A.
Decreasing the MCS value reduces the number of ports available.

B.
Changing MCS value requires the managed system to undergo a power cycle

C.
The VIO server must have the “cfgdev” command run to discover the new ports.

D.
The Host Ethernet configuration (available ports) must be changed to match the IVE
configuration.
