5.2.3 Making Initial Settings for the Control Domain


5.2.3 Making Initial Settings for the Control Domain
  1. Execute the ldm start-reconf command to start the delayed reconfiguration mode.
    The control domain name is fixed at "primary".
# ldm start-reconf primary
  1. Execute the ldm list-permits command to check the number of CPU cores that can be assigned.
# ldm list-permits
  1. Execute the ldm set-core command to assign a virtual CPU to the control domain.
    The following example assigns CPUs of 4 cores to the control domain.
# ldm set-core 4 primary
  1. Execute the ldm set-memory command to assign virtual memory.
    The following example assigns 8 GB of memory to the control domain.
# ldm set-memory 8g primary
  1. Execute the ldm list-bindings command to check the assignment status of resources.
# ldm list-bindings primary
  1. Execute the ldm add-spconfig command to save the logical domain configuration to the XSCF.
    The following example saves logical domain configuration information with the name "config1".
# ldm add-spconfig config1
  1. Execute the poweroff and poweron commands of the XSCF firmware to power off the physical partition and power it on again.
XSCF> poweroff -p 0
XSCF> poweron -p 0
  1. After restarting the control domain, execute the list-bindings command to check the assignment status of resources.
    If the following command displays the same the assignment status as described in step 4, the settings were made correctly.
# ldm list-bindings primary
