To suspend or resume application monitoring

After configuring application monitoring you may want to perform routine maintenance tasks on those applications. These tasks may or may not involve stopping the application but may temporarily affect the state of the applications and its dependent components. If there is any change to the application status, Cluster Server (VCS) may try to restore the application state. This may potentially affect the maintenance tasks that you intend to perform on those applications.

If stopping the application is not an option, you can suspend application monitoring and create a window for performing such maintenance tasks. When application monitoring is suspended, VCS freezes the application configuration.

The Enter Maintenance Mode link is automatically dimmed if the application is already in maintenance mode. Conversely, if the application is not in maintenance mode, the Exit Maintenance Mode link is dimmed.

The Veritas High Availability tab provides the following options:

To enter maintenance mode

  1. In the appropriate row, click More> Enter Maintenance Mode.

    During the time the monitoring is suspended, Veritas high availability solutions do not monitor the state of the application and its dependent components. The Veritas High Availability view does not display the current status of the application. If there is any failure in the application or its components, VCS takes no action.

  2. While in maintenance mode, if a virtual machine restarts, if you want application monitoring to remain in maintenance mode, then in the Enter Maintenance Mode panel, check the Suspend the application availability even after reboot check box, and then click OK to enter maintenance mode.

To exit the maintenance mode

  1. In the appropriate row, click More> Exit Maintenance Mode, and then click OK to exit maintenance mode.
  2. Click the Refresh icon in the top right corner of the Veritas High Availability view, to confirm that the application is no longer in maintenance mode.
