CSG is activated.
When you log on to the for the first time, activate the CSG service as prompted.
A virtual private cloud (VPC) is available in the region where you want to create a block gateway. For more information, see Create an IPv4 VPC.
An Elastic Compute Service (ECS) instance is available in the region where you want to create a block gateway. The ECS instance runs in the VPC. For more information, see Create an ECS instance.

Note If your on-premises host is connected to a VPC by using an Express Connect circuit, you can also manage the block gateway on your on-premises host.

Log on to the CSG console.
Select the region where you want to create a block gateway.
In the left-side navigation pane, click Gateways. On the Current Gateway Cluster page, select the gateway cluster, and then click Create.
If you have not created a gateway cluster, click Create Gateway Cluster on the Overview page to create a gateway cluster.

In the Gateway Information step, set the required parameters, and then click Next. The following table describes the parameters.


Parameter	Description
Name	The name of the gateway that you want to create. The name must be 1 to 60 characters in length and can contain letters, digits, periods (.), underscores (_), and hyphens (-). It must start with a letter.
Location	The location where you want to deploy the gateway. Valid values: On-premises and Alibaba Cloud. On-premises: specifies an on-premises block gateway that is deployed in your data center. You can deploy an on-premises block gateway either in the CSG console or in the on-premises block gateway console. Alibaba Cloud: specifies a cloud block gateway that is deployed on Alibaba Cloud. You can deploy a cloud block gateway only in the CSG console.
Type	The type of the gateway that you want to create. Select iSCSI Gateway.

In the Gateway Configurations step, set the required parameters, and then click Next.

If you set Location to Alibaba Cloud, you must set the following parameters in this step.

VPC	The VPC where you want to deploy the gateway. Note The specified VPC must be the VPC where your ECS instance or on-premises host resides.
vSwitch	The vSwitch that is connected to the gateway. Note The specified vSwitch must be the vSwitch that is connected to your ECS instance or on-premises host. If no gateway is available in the zone where the specified vSwitch resides, create a vSwitch in another zone.
Public Network Bandwidth	The public bandwidth. Note By default, Public Network Bandwidth is not selected. If you want to use a gateway that resides in another region, you must select and set the Public Network Bandwidth parameter. For more information, see Upgrade the public bandwidth.

In the Billing Information step, set the required parameters, and then click Next. The following table describes the parameters.


Parameter	Description
Billing Method	The method that the system uses to calculate fees for the gateway. Valid values: Pay-as-you-go and Subscription. For more information, see Billable items and billing methods. If you select Subscription, you are redirected to the Cloud Storage Gateway (Subscription) page after you create the block gateway. Then, you must complete the payment as prompted. For more information, see Purchase a subscription gateway.
Expiration Policy	Select an expiration policy for the gateway. Valid values: Switch to Pay-as-you-go and Release.

In the Confirmation step, confirm your settings, and then click OK.
- After you create a cloud block gateway, the system completes the deployment in 5 to 10 minutes. If the Running state is displayed in the Status column, the gateway is activated and deployed.
- After you create an on-premises block gateway, click Activate Gateway in the Actions column. In the Activate Gateway dialog box, set the required parameters to activate the gateway. For more information, see Activate the gateway.
