Reset the CPU/Memory Configuration

Use this procedure to return the system to the original state of socket/core/memory allocations without affecting other changes that were made in each of the domains since the system was set up initially. This option does not reset the SP configuration.

The syntax for this osc-setcoremem feature was introduced in SuperCluster version 2.3 software:

osc-setcoremem -R|reset [-y|-n]

The command supports these options:

  • -R or reset – Returns the CPU and memory configuration to the original configuration.

  • -y or -n – (Optional) If -y is specified, you are not prompted to confirm the operation, and he reset takes effect immediately. If -n is specified, the tool shows you the output as if the reset operation ran, but the CPU and memory allocations are not changed.

  1. Log in as superuser on the compute node's control domain.
  2. Reset the CPU and memory configuration.

    For example:

    # ./osc-setcoremem -reset

     CPU Granularity Preference:
    
            1. Socket
            2. Core
    
     In case of Socket granularity, proportional memory capacity is
      automatically selected for you.
    
     Choose Socket or Core [S or C] S
    
     Step 1 of 1: Socket Count
    
     primary      : specify socket count [min: 1, max: 1. default: 1] : 1
                    you chose [1] socket for primary domain
    
     ssccn1-dom1  : specify socket count [min: 1, max: 1. default: 1] : 1
                    you chose [1] socket for ssccn1-dom1 domain
    
     ssccn1-dom2  : specify socket count [min: 1, max: 1. default: 1] : 1
                    you chose [1] socket for ssccn1-dom2 domain
