# Scale Group Actions

Use this page to understand the lifecycle actions for a scale group: resizing the active node count, stopping and starting the group, and deleting it. Actions are available from the three-dot **Actions** menu on the Auto Scaling list and from the scale group details page.

The portal enables or disables each action based on the scale group's current **status** and your project permissions (update or delete). To edit a group's node counts or policies, see [Scale Group Details and Editing](/docs/myaccount/auto-scaling/manage/scale-group-details).

## Action Availability

| Action         | Available when status is                     | Disabled during             | Permission |
| -------------- | -------------------------------------------- | --------------------------- | ---------- |
| Resize Service | Running, Failed, or Failed Deleting          | Scaling                     | Update     |
| Start          | Stopped                                      | Starting, Stopping          | Update     |
| Stop           | Running                                      | Starting, Stopping          | Update     |
| Delete         | Running, Stopped, Failed, or Failed Deleting | Scaling, Starting, Stopping | Delete     |

If an action is visible but disabled, refresh the scale group and check its status. The portal disables actions while the group is transitioning (Creating, Scaling, Starting, Stopping).

## Resize Service

Use **Resize Service** to manually set the number of active nodes (the desired count / cardinality) — for example, to pre-warm capacity before a traffic event or a deployment.

The new value must be **between the minimum and maximum nodes** of the group.

To resize a scale group:

1. Open the **Actions** menu and select **Resize Service**.
2. In the **Resize Service** dialog, use the minus and plus controls to set the new active node count.
3. **If you are increasing the count above the current desired value**, choose how the minimum should behave:
   - **Also update minimum desired nodes to _N_** — raises the minimum so the elastic policy does not scale the group back down to the old minimum.
   - **Keep minimum at _N_** — leaves the minimum unchanged; the elastic policy may remove the extra nodes again when utilization is low.
4. Select **Resize Pool**.

:::note
**Resize Pool** stays disabled until you change the count away from the current value. The group moves through **Scaling** while nodes are added or removed.
:::

## Start

Use **Start** to bring a stopped scale group back online.

When you start a group, it returns to **Running** with all of your previously configured settings intact. The **desired node count is set to the minimum nodes**, and billing resumes.

To start a scale group:

1. Open the **Actions** menu and select **Start**.
2. In the **Confirm Start Scale Group** dialog, verify the scale group name.
3. Select **Start scale group**.
4. Wait for the status to move from **Starting** to **Running**.

---

## Stop

Use **Stop** to halt a scale group without deleting it.

When stopped, the group's **desired nodes are set to zero**, all group nodes are removed, and **billing for the scale group is paused**. Your configuration (image, plan, policies, network, and security group) is preserved so you can start it again later.

:::note
Starting a stopped group again restores all settings, with one change: the desired node count comes back at the **minimum nodes**, not whatever it was before the stop.
:::

To stop a scale group:

1. Open the **Actions** menu and select **Stop**.
2. In the **Confirm Stop Scale Group** dialog, read the notes — billing stops while stopped, and restarting brings desired nodes back to the minimum.
3. Select **Stop scale group**.
4. Wait for the status to move through **Stopping** to **Stopped**.

---

## Delete

Use **Delete** to permanently terminate a scale group and all of its nodes.

:::danger
Deleting a scale group is destructive. All group nodes are terminated. Make sure you no longer need the running nodes or any data on them before confirming.
:::

To delete a scale group:

1. Open the **Actions** menu and select **Delete**.
2. In the **Delete Scale Group** dialog, review the warning. If nodes are currently running, the dialog notes how many nodes are associated and reminds you that the group will be torn down.
3. Confirm the scale group name.
4. Select **Delete Scale Group**.
5. Wait for termination to complete.

After deletion, the saved image that was protected by this group can be deleted if it is no longer used elsewhere.

## API and Automation

You can run these lifecycle actions through the [Auto Scaling API](/api/myaccount/compute/auto-scaling/get-scaler-scalegroups) after creating an API token:
