Cluster Configuration - Prerequisites

Before you install the Commvault software in a cluster environment, review the following prerequisites and requirements.

  • Verify System Requirements

    Verify that the computer in which you want to install the software satisfies the minimum requirements specified in System Requirements.
  • Verify Network TCP Port Requirements

    For a given cluster server, the MediaAgent, Agent, or other software component installed on every physical node in a cluster which is configured to host that cluster server must have the same port numbers configured. Thus, if you have a cluster server VS1, and three physical computers configured to host VS1, then all the three computers must have the same Network TCP port numbers configured for the network interface used by VS1. For greater detail, consider this example:

    • Node A is configured to host cluster server VS1. Instance001 has the an Agent installed to protect application data on VS1; during install, Port 8502 was specified for the Communications Service (CVD) and Port 8503 was specified for the Client Manager Service (ClMgrS).
    • Node B is also configured to host VS1. Instance001 has the same Agent installed to protect the application data on VS1; during the Agent install, Port 8502 must be specified for the Communications Service (CVD) and Port 8503 must be specified for the Client Manager Service (ClMgrS) to match the Network TCP port number configuration of Node A.
  • Verify License Requirements

    Depending on the cluster type (Windows or Unix), the following table shows the file system and cluster licenses needed for the physical computer associated with the cluster group client:

    MediaAgent

    You must have a license for each physical and virtual node where the MediaAgent is installed. If you do not plan to use the MediaAgent on the physical nodes, install the MediaAgent as a Restore Only Agent, which does not consume a license.

    MediaAgent (Windows or UNIX) MediaAgents

    SAP HANA

    If you have a cluster environment configured with the SAP HANA application, you must obtain the following license:
