Cluster actions

This article describes the main actions available in the ADCM interface for working with an ADS Control cluster.

Actions with the cluster are performed on the Clusters page.

Page Clusters

The Clusters page contains a table with the following columns:

  • Name — the name specified when creating the cluster.

  • State — current state of the cluster (created, installed or upgrade from X.X.X).

  • Product — product name.

  • Version — version of the product bundle that was used to install the cluster.

  • Description — description specified when creating the cluster.

  • Concerns. The icon concern default serves as an indicator that the cluster is configured correctly. If critical errors are detected in the cluster configuration, the icon concern red dark concern red light is displayed in the column — when you hover over it, a window is displayed with a description of the error and a link that you can follow to perform the required configuration.

  • Actions. The column shows icons for cluster management:

    • actions default dark actions default light — opens a list of actions for working with the cluster.

    • upgrade default — indicates whether a new version of the bundle is available, and allows you to run cluster update to the new version.

    • delete default — deletes information about the cluster from ADCM (does not delete the cluster or make any changes to the hosts belonging to the cluster).

You can use the icons described above to perform the corresponding actions. Once an activity is started, ADCM displays its execution progress and result on the Jobs page. From this page you can go to the page of an individual task (by clicking on the task name) to see the internal stages of its execution and analyze errors if they occur.

When you select an action, ADCM displays a dialog box to confirm your selection. In this dialog box, you can select the Verbose check box to view additional information about the execution of the action on the Jobs page.

The set of available actions depends on the cluster state:

  • For new cluster (cluster state created) the following action is available:

    • Install — installs the cluster service.

  • After cluster installation (cluster state installed) the following actions are available:

    • Check — checks the health of the cluster.

    • Restart — stops and then starts the cluster.

    • Start — starts the cluster services.

    • Stop — stops cluster services.

    • Reinstall status-checker — initiates reconfiguration and restart of statuschecker for all cluster services. Used when migrating a cluster under the control of a new ADCM server.

  • For a cluster prepared for upgrade (the cluster state is upgrade from X.X.X), an available action is:

Cluster update

To update the cluster version:

  1. Download the bundle ADS Control new version — see step Upload a cluster bundle to ADCM in the Create a cluster article.

  2. Open the Clusters page. After downloading the bundle, the icon upgrade default becomes active.

  3. Click on the icon upgrade default. In the Upgrade Cluster window that opens, select the version available for upgrade and click Upgrade.

    update cluster
    Start upgrade
  4. In the dialog box that opens, click Run.

    update cluster 01
    Confirmation of preparation for update

    As a result, the status in the State column changes to upgrade from XXX (depending on the cluster version) — the cluster is ready for upgrade.

  5. Click the icon actions default dark actions default light in the Actions column and run the Upgrade action.

    update cluster 03
    Performing an update

    In the dialog box that opens, click Run to confirm the update. Once the upgrade process is complete, ADCM will change the cluster status to installed.
