Provisioning a command device for the UCP Advisor Worker Node VM

If your UCP system uses a storage system, you must provision the UCP Advisor Worker Node VM with a command device. It must be created in the meta_resource resource group.

Use the following procedure to provision a new command device to the UCP Advisor Worker Node VM on the management node.

kubectl get node -o wide -l app=ucp

1. Log on to vCenter Server Appliance.
2. Right-click UCP Advisor Worker Node VM, then select Edit Settings.
3. In New device, click Select.
4. Select RDM Disk, then click Add.
   
   
   
   
5. Select the target LUN, then click OK.
   
   
   
   
6. Click OK.
7. Using an SSH client, log on to the Master Node VM as ucpadmin.
8. Navigate to the installer folder.
9. Run the following command:

   sudo ./installer multi-node -U --prompt --master-node <Master Node IP/FQDN Address> --worker-nodes <Worker Node1 IP/FQDN Address> <Worker Node2 IP/FQDN Address>

   Note: You will be prompted to enter the Master Node VM username and password, and the UCP Advisor username and password. Verify that the username and password are the same for all the nodes. The UCP Advisor credentials are optional. However, Hitachi recommends to provide the UCP Advisor credentials to verify the tasks in the UCP Advisor UI.
10. Enter y when prompted.

    The console displays the following message:

    "Congratulations, the upgrade was successful."

11. Verify that the command devices are successfully added.
    1. In a web browser, enter the following URL:
       https://<UCP-Advisor-Address>:8444/services/cmd-devices
       This lists all the command devices.
