Plan the MediaAgent Installation

For a successful installation, some careful planning is required to ensure that Commvault integrates seamlessly with your environment.

Use the following checklist to prepare the computer where the MediaAgent will be installed:

Verify System Requirements

Make sure that the computer's operating system and hardware are supported by the MediaAgent. For more information, see System Requirements.

Verify License Requirements

Based on the licensing mechanism used in your CommCell environment, verify that the CommCell has the required licenses to use the MediaAgent. For more information, see License Requirements.

Verify Requirements for Installation Environments

  • If you plan to install the MediaAgent on a virtual machine, the virtual machine must be configured with fast-access storage media. Ensure that the CPU and memory resources recommended in System Requirements are always available for the virtual machine.
  • If you plan to configure a Docker container with a preinstalled MediaAgent image, follow the installation steps in Installing a MediaAgent Docker Image.

Determine the Role of Your MediaAgent

The MediaAgent can have different roles. Determine which of the following roles are required in your environment, and review their respective requirements:

Role

Requirements

MediaAgent as a Data Mover

The MediaAgent computer must meet the requirements specified in System Requirements.

MediaAgent to host the Deduplication database

The MediaAgent computer must meet the requirements specified in Deduplication Building Block Guide.

MediaAgent to host the Index Cache

The MediaAgent computer must meet the index cache requirements, as follows:

MediaAgent for Snap Copy

The client computer where you want to perform IntelliSnap backups must meet the MediaAgent requirements specified in System Requirements.

Download the Software

Choose one of the following methods to download the software:

Determine the Configurations that Meet Your Requirements

Every environment has different requirements. Consider the following additional configurations and information prior to completing your installation planning:

For Windows Computers

  • Install Commvault in a New Instance

If Commvault is already installed on the computer, but your environment requires the MediaAgent in a separate instance, you can install the MediaAgent in a new instance. For more information, see Multi-Instance Installations.

  • Configure a Floating Host Name

A floating host name is a virtual host name that is useful in those scenarios when the MediaAgent needs to be moved or changed at some point in time. For example, the floating name minimizes the downtime for failover operations when the MediaAgent undergoes a hardware refresh. For more information, see Configuring a Floating Host Name for the CommServe or MediaAgent Software.

For UNIX Computers

  • Install as a SUDO User With Root Privileges

If you want to install as a SUDO user, add the SUDO user to the /etc/sudoers file. For more information, see Adding SUDO Users with Root Privileges on a UNIX Client.

  • Install as a Non-Root User

If the computer where you want to run the installation does not have a root user defined, you can install agents as a non-root user. Before the installation, review the considerations described in Installation of UNIX Agents by a Non-Root User.

  • Install in a Predefined Directory or Mount Point

If you want to install in a predefined directory, review the considerations described in Installation of UNIX Agents in a Predefined Directory.

  • Install Commvault in a New Instance

If Commvault is already installed on the computer, but your environment requires the MediaAgent in a separate instance, you can install the MediaAgent in a new instance. For more information, see Multi-Instance Installations.

  • Change the Branding of the Installation Package

You can change the software name to a different name, such as your organization's name. For more information, see Changing the Branding of a UNIX Installation Package.

  • Configure the Kernel Parameter

You can configure or modify the kernel parameters on the MediaAgent. For more information, see Kernel Parameter Configuration.
