# Access to HCP REST

Hitachi Content Platform (HCP) is a distributed storage system that can be used through a VFS connection in the PDI client.

Within HCP, access control lists (ACLs) grant privileges to the user to perform a variety of file operations. [Namespaces](https://knowledge.hitachivantara.com/Documents/Storage/Content_Platform/8.1.2/System_administration/Introduction_to_Hitachi_Content_Platform/01_About_Hitachi_Content_Platform/), owned and managed by tenants, are used for logical groupings, access and permissions, and object metadata such as versioning, retention and shred settings. For more information about HCP, see the [Introduction to Hitachi Content Platform](https://knowledge.hitachivantara.com/Documents/Storage/Content_Platform/8.1.2/Tenants_and_Namespaces/Introduction_to_Hitachi_Content_Platform).

Perform the following steps to setup access to HCP:

**Note:** The following process assumes that you have HCP tenant permissions and that namespaces have been created. For more information, see [Tenant Management Console](https://knowledge.hitachivantara.com/Documents/Storage/Content_Platform/8.1.2/Tenants_and_Namespaces/General_administrative_information/03_Tenant_Management_Console).

**Note:** To create a successful VFS connection to HCP, object versioning must be configured in HCP [Namespaces](https://knowledge.hitachivantara.com/Documents/Storage/Content_Platform/8.1.2/Tenants_and_Namespaces/Managing_namespaces).

1. Log on to the HCP Tenant Management Console.
2. Click **Namespaces** and then select the **Name** you want to configure.

3. In the **Protocols** tab, click **HTTP(S)**, and verify **Enable HTTPS** and **Enable REST API** with **Authenticated access only** are selected.
4. In the **Settings** tab, select **ACLs**.
5. Select the **Enable ACLs** check box and, when prompted, click **Enable ACLs** to confirm.

This completes the setup of HCP for accessing files in the PDI client.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/pdia-data-integration/archived-merged-pages/connecting-to-virtual-file-systems-archive/before-you-begin-vfs-connections/access-to-hcp-rest.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
