Overview

Renewal Introduction

After a yearly/monthly DWS cluster expires, it cannot run properly. If you want to continue using it, you need to renew the DWS cluster subscription within a specified period. Otherwise, resources, such as CPUs, memory, and EVS disks, will be automatically released, and data will be lost and cannot be restored.

Only yearly/monthly DWS cluster and discount package subscriptions can be renewed. If you use a pay-per-use DWS cluster, just ensure that your account has a valid payment method configured or a top-up account with a sufficient balance.

If you renew the cluster before it expires, resources will be retained and you can continue using the cluster. For details about DWS cluster statuses after they have expired and the associated impacts, see Impact of Expiration.

Renewal Functions

Table 1 describes the functions related to the renewal of yearly/monthly DWS clusters.

You can select a method to renew a yearly/monthly DWS cluster based on the phase the cluster is currently in.

Figure 1 DWS cluster Lifecycle

• A DWS cluster is in the Running state after it is provisioned.
• When a subscription expires, the status will change from Running to Expired.
• If the DWS cluster is not renewed upon expiration, it enters the grace period. If it is not renewed after the grace period ends, the status changes to Frozen.
• If you do not renew the subscription before the retention period expires, the corresponding resources will be automatically deleted.

  You can enable auto-renewal anytime before a DWS cluster expires. By default, the system will make the first attempt to charge your account for the renewal at 03:00 seven days before the expiration date. If this attempt fails, it will make another attempt at 03:00 every day until the subscription is renewed or expires. By default, renewal charges are deducted from your account seven days before the new expiration date. You can change the auto-renew payment date as required.
