Revert to a Previous CPU/Memory Configuration

Use this procedure to revert a compute node to a previous CPU/Memory configuration. You must perform this procedure on each member in a cluster. The tool does not automatically propagate changes to every cluster member.

Note -  To find out if you can perform this procedure, see Supported Domain Configurations.
  1. Log in as superuser on the compute node's control domain.
  2. List previous configurations.

    Note -  You can also view previous configurations in the log files. See Access osc-setcoremem Log Files.
    # ldm list-config
    CM_1S1T_6C512G_082820151618 [current]

    For details about SP configuration files see View the SP Configuration.

  3. Revert to a previous configuration.
    # ldm set-config CM_30C2560G_18C1536G_082820151559
  4. Halt all domains, then halt the primary domain.
  5. Restart the system from the service processor.
    # #.
