A production application is hosted across two Power 750 Express servers, managed by an HMC.
Each machine has 16 cores and 32GB RAM. Four 8GB LPARs are defined across the two
systems and only 3 LPARs are active at once. Live Partition Mobility is used to maintain
availability when maintenance is required.
A test environment is being built across two Power 550 Express servers.

Each machine has 8 cores and 16GB RAM. Four 4GB LPARs will be defined across the two
systems, again only 3 will be active at once. To isolate the test and production environment, the
test environment is managed by two IVMs.
Two LPARs have been created on each test server. The administrator initiates a Live Partition
Mobility operation to test moving LPARs between the servers.
The migrlpar command fails to migrate the 4th LPAR with the following error:
“The target managed system does not have enough available memory to create the partition.”
Because the 4th LPAR was inactive, it was expected that an inactive migration would be
successful.
Why would this inactive migration fail on the test environment, but succeed on the production
environment?

A.
IVM-managed systems do not support inactive migrations.

B.
IVM-managed systems reserve RAM allocations, even for inactive LPARs.

C.
The target managed system already has the maximum number of partitions.

D.
Active Memory Sharing (AMS) or Active Memory Expansion (AME) is required for RAM over
commitment.
