Before you can use the MemCPUAllocator agent, you need to set up SSH access between the HMC and the DLPAR nodes. You must also make sure to configure the MemCPUAllocator resource as a leaf node in the service group's dependency tree in the main.cf file.

See Figure: Sample service group that includes a MemCPUAllocator resource, where the MemCPUA resource represents the MemCPUAllocator resource.

Provide values to the MemCPUAllocator resource to specify the resource requirements for that service group. For example, if a service group needs 512 MB memory and two CPUs to start with, the MemCPUAllocator resource definition resembles:

MemCPUAllocator mymem (
    ManagedSystem @eagle = eagle-server
    ManagedSystem @vulture = vulture-server
    HMC = { testhmc }
    RequiredMemory = 512
    RequiredCPU = 2
    MemoryCritical = 1
    CPUCritical = 1
)
