Cluster actions
This article describes actions available for working with an ADQM cluster in the ADCM interface. You can find cluster actions on the CLUSTERS tab.
The CLUSTERS tab displays a table with the following columns:
-
Name — name specified during the cluster creation.
-
Bundle — name of a bundle used to install the cluster.
-
Description — description specified during the cluster creation.
-
State — the current state of the cluster (
created,installed, orupgradable). -
Status. When you click the Status icon
, a browser opens the Status page of the cluster menu where you can view statuses of all cluster services and their components. The icon image changes depending on the current state of the cluster. If the cluster does not work correctly, the Status warning 
icon is displayed. -
Actions. When you click the Actions icon
, the drop-down list offers actions to manage the cluster. -
Import. When you click the Import icon
, a browser opens the Import page. -
Upgrade. The Upgrade icon
indicates whether a new version of a bundle is available and allows you to upgrade the cluster version. -
Config. Clicking the Config icon
opens the Configuration page. See the Configure a cluster article for more information on this page. -
The last column contains the Delete icon
to remove a cluster.
You can click icons from columns described above to perform the corresponding cluster actions. When an action starts, ADCM displays its execution process and result on the JOBS tab. On this tab, you can expand complex action nodes to see inner steps, and analyze errors if they occur.
Actions
Click the Actions icon to display a drop-down list with available actions and select an action to run it.
When you choose an action, ADCM displays a dialog window to confirm the choice. In this dialog window, you can select the Verbose checkbox to see additional execution details on the JOBS tab.
A set of available actions depends on the cluster state:
-
For a new cluster (the cluster state is
created), an available action is:-
Install — installs all cluster services.
-
-
After a cluster is installed (the cluster state is
installed), the following actions are available:-
Check — checks if all components of the installed cluster work correctly.
-
Enable Kerberos — enables Kerberos authentication. After this action has been performed, the Disable Kerberos (disables Kerberos authentication) and Reconfig Kerberos (applies changes made to Kerberos configuration files and settings) actions appear.
-
Reinstall status-checker — reconfigures and restarts the status checker for all cluster services. Use this action when migrating a cluster to a new ADCM server.
-
-
For a cluster prepared for upgrade (the cluster state is
upgradable), an available action is:-
Upgrade — upgrades the cluster version.
-
Import
When you click the Import icon , a browser opens the Import page. On this page, you can select components of other clusters (for example, monitoring components) that should be integrated to the ADQM cluster.
Upgrade
To upgrade an ADQM cluster version, you need to upload a new bundle first. To do this, switch to the BUNDLES tab, click Upload bundles, and select a new bundle file in your environment.
If you see an exclamation mark 
in the Edition column, you need to sign the license agreement to use the uploaded bundle. Click , read the agreement, and click Yes to accept it.
After a new bundle is loaded, open the CLUSTERS tab. The Upgrade icon becomes active 
— click it and select the available version from the drop-down list.
After you select an upgrade version, a confirmation dialog window appears. Click Run.
As a result, ADCM changes the cluster state to upgradable — the cluster is ready for upgrade. Click the Actions icon and select the Upgrade action.
In the dialog that opens, click Run to confirm the upgrade. Once the upgrade process is complete, ADCM will change the cluster state to installed.
