Preinstallation Checklist for the Command Center on UNIX

Use this preinstallation checklist to prepare the computer where the Command Center will be installed and to gather all of the information you will need during the installation.

Verify System Requirements

Verify that the computer where you will install the Command Center satisfies the minimum requirements. For more information, see System Requirements - Web Console and Command Center.

Verify License Requirements

The Command Center does not require a license.

Determine the Installation Location

Based on your environment, install the Command Center on an appropriate computer.

  • The Command Center can be installed on a separate computer than the CommServe and Web Server computers to support the following:

    • Offloading the Command Center processes from the CommServe or Web Server computers.

    • Setting up the Command Center in a perimeter network outside of the organization's network to provide global access for external users.

  • If you install the Command Center on a separate computer, that computer must be able to connect to the Web Server and CommServe computers.

  • The Command Center cannot be installed on a clustered environment. For example, if you plan to install the Command Center on the CommServe computer, but the CommServe computer is installed on a clustered environment, then you must install the Command Center on a different computer.

Gather Installation Data

Refer to the items in this section to gather the information that you will need during the installation. Record the information before you begin installing the software, so you can refer to it during the installation.

You can install the Command Center by using either the CommCell Console or the installation package created by the Download Manager.


If you plan to install the Command Center on a computer that has other server components installed, only the following information is required:

  • Commvault package to install

  • Destination folder for the software installation

Commvault package to install

  • For installations using the CommCell Console, install the Command Center package, which is listed under the Server category.

  • For installations using the installation package, install the Command Center package.

Installing multiple instances of the Command Center package is not supported on Linux computers.


If the File System Agent is not installed on the computer, the File System Core and File System packages are automatically installed with the package you selected. The File System Agent will not consume any license.

To gather the required information for the File System Agent, refer to the Gather Installation Data section in the Preinstallation Checklist for the Unix, Linux and Macintosh File System Agent.

Client computer details

If the File System Agent or another package is already installed on the computer, you are not required to gather all the computer details again. The level of detail depends on how the package you selected is installed, as follows:

  • For installations using the CommCell Console, the installation program requests only the name of the client computer.

  • For installations using the installation package, the installation program reads the details from the previous installation.

Installation directory

  • By default, the software binaries are installed in /opt/commvault.

You can change the directory to a different local directory or to an NFS share. If you decide to use an NFS share, make sure that it is always mounted and accessible by the Commvault software.
