The following are the steps to validate a successful scale out/in operation in PSIM.

  1. On the PSIM node, run the following command to check if the correct number of nodes are observed.
    # psim-ecosystem-state
    
    A sample output:
    # psim-ecosystem-state
    All 8 Nodes in Contact - OK
    Database TDLabs - OK : RUN/STARTED
     
    -- Summary --
     
    PSIM - 3 nodes total
    TPA - 2 nodes total
    Ecosystem - 3 nodes total
    
  2. As the DSC fabric requires manual updates if there are any changes to the media server name, run # dsc config_fabrics -f <file_name>.xml.

    To validate the TPA nodes have the correct IP address, view the following file in PSIM node. A sample file and output is shown here.
    cat /var/opt/teradata/psim/config/ecosystem.json
    {
        "non_sqle_node_list": [
            {
                "ip_addr": "10.27.01.144"
            },
            {
                "ip_addr": "10.27.90.115"
            },
            {
                "ip_addr": "10.27.101.55"
            }
        ],
        "psim_domain_settings": {
            "serviceconnect": "PROD",
            "site_id": "ATSTLES4"
        },
        "psim_list": [
            {
                "ip_addr": "10.27.123.34",
                "type": "psim"
            },
            {
                "ip_addr": "10.27.141.1",
                "type": "psim"
            },
            {
                "ip_addr": "10.27.191.143",
                "type": "psim"
            }
        ],
        "psim_metadata_version": "1.0",
        "sqle_instance_list": [
            {
                "database_name": "TDLabs",
                "node_list": [
                    {
                        "ip_addr": "10.27.26.21"
                    },
                    {
                        "ip_addr": "10.27.19.186"
                    }
                ]
            }
