--- title: "Installing an Additional External Platform Services Controller (PSC)" canonical: "https://www.virtcloudrocks.com/space/VSPHTECH01/852123/Installing%20an%20Additional%20External%20Platform%20Services%20Controller%20(PSC)" format: markdown --- To proceed with this part, it is assumed that we have already deployed and configured an External PSC, following a previous article of mine, (see the side references). If you recall our ultimate scope is to create two external PSCs which will be load-balanced, for high-availability purposes, and will be linked with an external vCenter Server. Similarly to previous article, the deployment of the new external PSC wtakes place in two stages, (a) towards the stage 1 it takes place the deployment of the appliance, and (b) towards the stage 2 it takes place the configuration of the PSC/appliance. Stage 1 Description of Task / Action to be done Screenshot Step 1 Mount the ISO file download to the client machine through which you will perform the installation. After the file is loaded, go to /vcsa-uiinstaller folder → select folder based on OS of your client → and run the installer file. The vCenter Server Appliance 6.5 installation page opens. To continue further click the Install button to start the installation. Step 2 Introduction of the installation process, press Next to continue further. Step 3 Accept the EULA Terms & Conditions and press Next to continue further. Step 4 Since we shall deploy external PSC, select Platform Service Controller , and press Next to continue. Step 5 Provide the IP or FQDN of the ESXi host or vCenter to which the PSC will be deployed to. Furthermore, provide the authentication credentials. In our case we deploying to an ESXi host, so we provided the IP address of the host, root account authentication credentials. Press Next to continue further with the installation process. Step 6 Accept the SSL certificate of the ESXi host. Step 7 Provide the VM name for the appliance, and root account password to be set towards the deployment process. Step 8 Select the datastore to which the appliance will be deployed to, and you may also enable Thin Mode . Press Next to continue further. Step 9 Provide the network configuration settings for the PSC appliance. Please note that as system name you need to provide the FQDN of the PSC appliance. Step 10 Verify all the settings and press Finish in order to complete the initial part of the PSC deployment. Step 11 Wait for the Stage 1: Deployment of Appliance to be completed. When the deployment has completed, the button changes to Close (from Cancel). Press Continue , to continue with Stage 2 deployment/configuration of the appliance. Stage 2 Description of Task / Action to be done Screenshot Step 1 Some generic information for the stage 2 process is presented Press Next to continue with the next step. Step 2 Configure the NTP server(s) for time synchronization, and you also have the option to enable SSH access. Press Next to continue with the next step. Step 3 At this point, since we have already deployed a PSC, we will select Join an existing SSO domain , in order to link this PSC with the existing one; provide all the necessary information, Platform Service Controller: Single Sign-On Domain Name : vsphere.local Single Sign-On User Name: administrator Provide the password for SSO account Press Next to continue with the next step. Step 4 At the SSO configuration dialog box, click Join an existing SSO site and fill in the SSO domain information. Click Next . Step 5 Choose if you want to participate to VMware CEIP. Press Next to continue with the next step. Step 6 Verify all the configuration settings provided and press Finish . Step 6 You can monitor the appliance's configuration process. While the appliance setup is in progress dialog box, wait for the setup to complete. At the Complete dialog, you can find a link to the vSphere Web Client interface. This completes stage 2 of the deployment process and set up of the PSC appliance.
