# Creating a Commvault Grid Storage Pool

A Commvault Grid storage pool is a scale-out storage resource that combines multiple Commvault Grid nodes into a single storage platform. In most deployments, the software automatically creates a storage pool during the Commvault Grid installation process.

If storage pool creation fails during deployment, or if additional storage pools are required, you can create a storage pool manually. After the Commvault Grid nodes are deployed and registered, a storage pool must be available to support data protection workloads, deduplication, and storage management operations.

When a stand-alone web server is used, the storage pool is not created automatically and must be created manually from the Command Center.

Use this procedure to create a Commvault Grid storage pool from previously configured Commvault Grid nodes.

## Before You Begin

- Verify that the Commvault Grid nodes have been successfully deployed and configured as described in Setting Up the Network.

- Verify that all nodes intended for the storage pool are registered and available in the CommCell environment.

- Download and install the latest updates associated with the release before creating the Commvault Grid storage pool.

- If multiple instances of the MediaAgent software are installed on a node, only one instance can be used to configure a Commvault Grid storage pool.

  For information about multi-instance installations, see Multi-Instance Installations.

  For example, if MA1 is installed in Instance001 and MA2 is installed in Instance002, you can create only one Commvault Grid storage pool using either MA1 or MA2. Do not use the other MediaAgent instance on the same node to configure another Commvault Grid storage pool.

## Procedure

1. The Commvault Grid page appears.

2. Click Add.

   The Add HyperScale page appears.

3. In the Name box, type a name for the Storage Pool.

4. From the Nodes list, select the names associated with the nodes that were configured.

5. Click Save.

## Result

After the storage pool is created:

- The storage pool appears under Storage Pools in the Command Center.

- A global deduplication policy is automatically created and appears under Policies > Storage Policies.

- The storage pool becomes available for creating storage policies and protecting workloads.

## What To Do Next

After creating the storage pool, create a storage policy or storage policy copy and associate it with the global deduplication policy.
