Park Cores and Memory
This is an example of a plan that reduces resources for
primary
,
ssccn2-dom2
,
ssccn2-dom4
,
so that the resources are parked (unallocated). The parked resources can later be used by I/O
Domains.
This table shows the allocation plan (see
“Plan CPU and Memory Allocations” on page 175
).

1.
Log in as superuser on the compute node's control domain.
2.
Activate any inactive domains using the
ldm bind
command.
The tool does not continue if any inactive domains are present.
3.
Run
osc-setcoremem
to change resource allocations.
In this example, some resources are left unallocated which parks them.
Respond when prompted. Press Enter to select the default value.
