CPU allocation preference:
1. Socket level
2. Core level
In case of Socket level granularity, proportional memory capacity is
automatically selected for you.
Choose Socket or Core level [S or C]
user input: 'C'
Step 1 of 2: Core Count
primary : specify number of cores [min: 2, max: 46. default: 12] :
user input (desired cores): '18' you chose [18] cores for primary domain
ssccn3-dom1 : specify number of cores [min: 2, max: 30. default: 2] :
user input (desired cores): '30' you chose [30] cores for ssccn3-dom1 domain
Configuration In Progress After Core Count Selection:
+----------------------------------+-------+--------+-----------+--- MINIMUM ----+

Step 2 of 2: Memory Capacity
(must be 16 GB aligned)
primary : specify memory capacity in GB [min: 96, max: 2016. default: 2016] :
user input (desired memory): '1536' GB you chose [1536 GB] memory for primary domain
ssccn3-dom1 : specify memory capacity in GB [min: 128, max: 2560. default: 2560] :
user input (desired memory): '' GB you chose [2560 GB] memory for ssccn3-dom1 domain
Configuration In progress After Memory Capacity Selection:

Following domains will be stopped and restarted:
ssccn3-dom1
This configuration requires rebooting the control domain.
Do you want to proceed? Y/N :
user input: 'y'
IMPORTANT NOTE:
+- -+
| After the reboot, osc-setcoremem attempts to complete CPU, memory re-configuration. |
| Please check syslog and the state of all domains before using the system. |
| eg., dmesg | grep osc-setcoremem ; ldm list | grep -v active ; date |

Please wait while osc-setcoremem is setting up the new CPU, memory configuration.
It may take a while. Be patient and do not interrupt.
