Preinstallation Checklist for the Cassandra Agent on UNIX

Use this preinstallation checklist to prepare the computer where you will install the Cassandra Agent, and to gather all of the information you will need during the installation.

Determine the Installation Location

The Commvault software installs the Cassandra package on the nodes that you select.

Verify System Requirements

Verify that the computer where you plan to install the Cassandra Agent satisfies the minimum requirements. For more information, see Cassandra Agent 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 Cassandra Agent. For more information, see License Requirements.

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 Cassandra 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

For installations using the CommCell Console, install the Cassandra package, which is under the Database category.

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.

UNIX Group and Access Permissions

If you did not assign a UNIX group during the installation of the File System agent, make sure to do the following during the installation:

  • Assign the UNIX group that is used by the database application

  • Include the database users into the group

You will be able to set the access permissions for the group. By default, read/write/execute permissions are granted to the UNIX group.

Cassandra Options

The Cassandra major versions are:

  • 2 for DSE 4.x versions and Cassandra 2.x versions

  • 3 for DSE 5.x, 6.x versions and Cassandra 3.x, 4.x versions
