View the SP Configuration

When you reallocate resources using the osc-setcoremem command, osc-setcoremem saves the new configuration to the service processor (SP) in this format:

CM_dom1_dom2_dom3_..._TimeStamp

where:

• CM_ – indicates a core/memory configuration that was created sometime after the initial installation.

• domx is expressed with this nomenclature:

  • xC or xS – CPU resources in number (x) of cores (C) or sockets (S)

  • xG or xT – Memory resources in number (x) of gigabytes (G) or number of terabytes (T)

• TimeStamp – in the format MMDDYYYYHHMM

This file name example . . .

CM_2S1T_1S512G_3S1536G_082020151354

. . . represents a configuration created on August 20, 2015 at 13:54 and has three domains with these resources:

• 2-sockets, 1-TB memory

• 1-socket, 512 GB memory

• 3-sockets, 1536 GB memory

To see more details about the resource allocations, you can use the SP configuration timestamp to locate and view the corresponding osc-setcoremem log file.

1. Log in as superuser on the compute node's control domain.
2. Display the SP configuration.

   Examples:

   • Output indicating no custom CPU/memory configurations:

     The file called V_B4_4_1_20150804141204 is the initial resource configuration file that was created when the system was installed.

     # ldm list-config
     factory-default
     V_B4_4_1_20150825155356 [next poweron]

   • Output indicating three additional CPU/memory configurations:

     # ldm list-config
     factory-default
     V_B4_4_1_20150825155356
     CM_3S3T_1S1T_082820151531
     CM_30C2560G_18C1536G_082820151559
     CM_1S1T_6C512G_082820151618 [current]
