# Installing the Production CommServe Host

Install the Commvault software packages on the production CommServe host.

Important

Starting Long-Term Support Release 11.40, new installations of the control plane on Windows require an additional setting to work. For instructions, see Enabling Windows Installations for Commvault.

Commvault strongly encourages you to transition to a Linux environment for Control plane components, specifically CommServe, Web Server, and Command Center. The Linux platform offers significantly better performance, enhanced stability, and superior resource efficiency when running Commvault.

## Before You Begin

- Verify that the prerequisites needed to setup the environment are available before setting up the CommServe LiveSync feature. For more information on the components needed to setup CommServe LiveSyncs, see Planning for the CommServe LiveSync Setup.

- Download the Commvault software installation packages from the Commvault Store.

    The software installs the prerequisite binaries for setting up the CommServe server. This process may take a few minutes.

    The Client Computer Information page is displayed.

19. Verify/modify the names and then click the arrow to proceed.

    - Client Name is the name of the CommServe client that will be displayed in user interfaces like Command Center / CommCell Console.

    - Host Name is the physical name (FQDN) of the server.

    The Client Name and Host Name prompts are for the CommServe client in the production CommServe host. (This is the CommServe client installed in Instance001. Note that this is the name used by clients to connect to this CommServe when it is active.)

    Tip

    Choose a meaningful Client Name to clearly differentiate this client in the user interfaces like Command Center / CommCell Console. For example, you can add the words Active or Production to differentiate it from the Standby CommServe client.

    Make a note of the fully qualified domain name (FQDN) that is displayed in the Host Name box. You will need to install the SQL clients in both the production host and the standby CommServe host.

    The Database Install Option page is displayed.

20. Choose the Create New Database option, and then click the arrow to proceed.

    The software creates the databases and services. This process may take a few minutes.

    The Commvault ID page is displayed.

21. Specify the account details for the admin account, and then click the arrow to proceed.

    Tip

    Make a note of the account details. You will need the account details to install the SQL clients in both the production host and the standby CommServe host.

    The software configures the CommServe setup. This process may take a few minutes.

    Note

    This completes the CommServe installation and the following prompts are displayed for installing the SQL client.

    - Client Name is the name of the SQL client that will be displayed in user interfaces like Command Center / CommCell Console.

    - Host Name is the physical name (FQDN) of the server.

    The Client Name and Host Name prompts are for the SQL client in the production CommServe host. (This is the standalone SQL agent installed in Instance002 which is used for backing up the SQL database from the production CommServe host. Note that this is NOT the name used by clients to connect to this CommServe host when it is active - the CommServe Client name used by clients, was already provided in Step 18.)

    Tip

    Choose a meaningful Client Name to clearly differentiate this client in the user interfaces like Command Center / CommCell Console. For example, you can add the word SQL to differentiate it from the CommServe client.

    The Server Information page is displayed.

26. Select / enter the following information:

    - Select the CommServe will connect to this computer to finish registration later option if the CommServe computer must initiate communications with the client.

      This is the CommServe host name that you noted while installing the production CommServe host in step 18.

    - Select Post Quantum Cryptography (PQC) mode enabled on Commserve if PQC is enabled on the CommServe server. PQC encrypts and decrypts data to protect it from attacks by quantum computers.

      Note

      - Post-quantum cryptography can be configured only at the CommCell level.

      - For information about enabling PQC, see Enabling Post Quantum Cryptography.

    The Server Authentication page is displayed.
