The following prerequisites are required to add additional nodes:
Existing Node Requirements
Check the following minimum required versions in your existing setup and make sure to upgrade the versions where needed.
-
HyperScale X backup gateway version
View the version for the HyperScale X backup gateways associated with the storage pool in which you plan to add the new nodes to make sure that Commvault Platform Release 2023E (11.32.35) or higher is available. . Verify and ensure that all the backup gateways in the storage pool have the same software version.
If one or more backup gateway is in an earlier version, update the software to the latest maintenance release version as described in Updating the backup gateway software.
-
HyperScale X platform version
View the HyperScale X platform version in the existing nodes to make sure that HyperScale X Platform Version 2.2408 (or later) is available.
Verify and ensure that all the nodes in the storage pool have the same platform version.
If one or more nodes is in an earlier version, install the OS updates as described in Installing Operating System Updates.
New Node Requirements
Consider the following before adding new nodes:
-
New nodes must be identical to the existing nodes in the storage pool, with the same drive count and drive size.
Mixing of certified hardware vendors or server generations is supported provided the same drive count and drive size is maintained.
-
A maximum of 12 nodes can be added to an existing storage pool.

New Node Setup
Setup the hardware in the new nodes using the following information:
-
Determine the network configuration in your existing setup
You must setup the new nodes using the same topology that was originally used in your existing setup. Check your existing network configuration to understand the network topology used in the existing nodes.
For more information about the supported topologies, see Determining the Network Topology.
-
Setup the DNS
Setup the necessary DNS records for the new nodes.
For more information, see Setting Up the DNS.
-
Setup the Switches
Ensure that the switch configurations are in place depending on the network topology in your environment.
For more information, see Setting Up the Switches.
-
Set up the installation media
Download and set up the recent version of the installation media on the Hyperscale X nodes.
For more information, see Setting Up the Installation Media.
-
Verify HyperScale X Image Version
Check the HyperScale X image version on the new nodes to ensure that the image version is Hyperscale ISO 3.2312.
If the image in the nodes is in an earlier version, re-image the new nodes with the most recent version, and then add the new nodes.
For more information, see Re-Imaging Nodes.
-
Obtain the Commvault Cloud credentials
Obtain the necessary credentials to connect to the Server Gateway.
For more information, see the Commvault Cloud Credentials section in Obtain the Server Gateway Name.
