# Create Host Aggregate

You can create a host aggregate by grouping multiple hosts that share a common capability.

You must be a PMO administrator to perform this operation.

To add a host aggregate, follow the steps given below.

1. Log in to Clarity.
2. Click Infrastructure in the left panel.
3. Click the Host Aggregates tab.
4. Click Add a New Host Aggregate.
5. Enter the aggregate name in Name.
6. Select the Create new availability zone if there is no existing availability zone or if you wish to create a new availability zone. This is an optional step. Enter the name of the new availability zone in Availability Zone Name.
7. Click Add key-value metadata to add SSH key value pairs to access the host aggregate. Repeat the step to add the required number of SSH key-value pairs.
8. Select the check boxes for the hosts to be included in the host aggregate from the list of hosts.
9. Click Create Host Aggregates.

A host aggregate is created.

If you have created a new availability zone, the newly created availability zone is visible under Infrastructure -> Host Aggregates -> Availability Zones.

## 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.platform9.com/managed-openstack/5.6/infrastructure/host-aggregates/infrastructure-create-host-aggregate.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.
