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 Active Directory Agent using either the CommCell Console or the installation package created by the Download Manager. Any item that applies to only one of these installation methods is noted.

Commvault Package to Install

Install the Active Directory package, which is listed under the Application category.


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 that you selected. The File System Agent will not consume any licenses.

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