Park Cores and Memory
Task complete with no errors.
This concludes socket/core, memory reconfiguration.
You can continue using the system.
4.
If the tool indicated that a reboot was needed, after the system reboots, log in as
root on the compute node's control domain.
5.
Verify the new resource allocation.
You can verify the resource allocation and check for possible osc-setcoremem errors in several
ways:
■
“Display the Current Domain Configuration (osc-setcoremem)” on page 178
■
“Display the Current Domain Configuration (ldm)” on page 180
■
“Access osc-setcoremem Log Files” on page 196
6.
Verify the parked cores.
In this example, there are 64 parked cores from these domains:
■
28 cores were parked prior to the resource allocation (These cores were placed in the logical
CPU repository when the Root Domain was created)
■
36 cores are parked from ssccn2-dom1, ssccn2-dom3, and ssccn2-dom5.
# ldm list-devices -p core | grep cid | wc -l

7.
Verify the parked memory.
In this example, memory is parked:
■
2 x 224 memory blocks are parked from the Root Domain.
■
The other memory blocks are parked from the dedicated domains.
When the memory is added together it equals approximately 1088 GB.
