Viewing Basic Cluster Information and Modifying Cluster Configurations

Scenario

After creating a CDM cluster, you can view its basic information and modify its configurations.

• You can view the following basic cluster information:
  • Cluster information: cluster version, creation time, project ID, instance ID, and cluster ID
  • Instance configuration: cluster flavor, CPU, and memory
  • Network configuration
• You can modify the following cluster configurations:
  • Notification: If a CDM migration job (only table/file migration) fails or the EIP is abnormal, CDM sends an SMS or email notification to the user. Notifications generated by this function will not be charged.
  • User isolation: determines whether other users can operate the migration jobs or links in the cluster.
    • If this function is enabled, migration jobs and links in the cluster are isolated. Other IAM users of the HUAWEI CLOUD account cannot operate the jobs and links.
    • If this function is disabled, migration jobs and links in the cluster can be shared by users. All IAM users with the required permission in the HUAWEI CLOUD account can view and perform operations on the jobs and links in the cluster.

      After disabling User Isolation, restart the cluster VM for the settings to take effect.

• Managing cluster tags

  You can add, modify, and delete CDM cluster tags. Tags can be used to identify multiple types of cloud resources. Cloud resources with the same tag can be filtered out in the TMS tag system.

  NOTE:

  A maximum of 10 tags can be added to a CDM cluster.

Prerequisites

You have created a CDM cluster.

Viewing Basic Cluster Information

1. Log in to the CDM console. In the left navigation pane, choose Cluster Management.

   NOTE:

   The Source column is displayed only when you access the DataArts Migration page from the DataArts Studio console.

2. Click the cluster name to view its basic information.

Modifying Cluster Configurations

1. Log in to the CDM console. In the left navigation pane, choose Cluster Management.

   NOTE:

   The Source column is displayed only when you access the DataArts Migration page from the DataArts Studio console.

2. Click the name of a cluster and click the Cluster Configuration tab to modify Notification and User Isolation configuration.
3. Click Save. The Cluster Management page is displayed.
4. If User Isolation is disabled, choose More > Restart in the Operation column to restart the cluster VM for the settings to take effect.

   • Restart CDM service process: Only the CDM service process is restarted. The cluster VM will not be restarted.
   • VM restart: The service process will be interrupted and VMs in the cluster will be restarted.

5. Select VM restart and click Yes.

Managing CDM Cluster Tags

1. Log in to the CDM console. In the navigation pane, choose Cluster Management.

   NOTE:

   • A cluster can have a maximum of 10 tags.
   • A tag key and a tag value can contain a maximum of 36 and 43 characters, respectively.

4. (Optional) In the tag list, click Edit or Delete in the Operation column to modify or delete tags.
5. On the TMS console, set resource search criteria and click Search to search for the tags you added.
