Creating a redundancy group template

To create a redundancy group template:

  1. Right-click the view in the Surveyor where you want to create the new redundancy group template and select New > Redundancy group template.

  2. On the first tab page, enter a name. Optionally, you can also add a description, and select the DMA that has to host the redundancy group template.

  3. On the Configuration tab page, in the Protocol section, select the protocol and a protocol version for the elements that will be added to the redundancy group template.

  4. If you wish to use software redundancy:

    1. In the Redundancy mode section, click the underlined section and select intervene in the switching (software redundancy).

    2. On the same line, click the underlined section to the right of redundancy mode and specify the redundancy mode.

      Note

      For more information on the different redundancy modes and on how to switch between redundancy modes after the redundancy group has been created, see Changing the redundancy mode.

    3. If you want the conditions of the switching logic to also be checked when a user does a manual switch, in the Redundancy mode section, select On manual switchover to a backup, also check the conditions from the switching logic.

    4. In the Switching logic section, click add and select Add switching logic. A first empty switching condition will then be displayed.

    5. Configure the switching condition by clicking the underlined fields and selecting the appropriate values, and add more conditions with the Add field below the condition if necessary:

      • The switchover and switchback actions can be triggered by an alarm, an element state or a parameter value. If connectivity has been configured on the DMA, they can also be triggered based on whether an element is in the active connectivity chain.

        Tip

        See also: Defining connectivity chains in XML files

        Note

        Prior to DataMiner 9.5.5, the connectivity path is only calculated starting from an internal connection, so that a connectivity chain path with only external connections cannot cause a redundancy group to switch. From DataMiner 9.5.5 onwards, this restriction no longer applies.

      • With the last field of a condition, you can indicate whether the condition has to persist for a certain time or not before its result is triggered.

      • Next to by executing, you can configure what should happen during a switch: a parameter set or an Automation script execution.

  5. In the Switching Detection section, specify when a switchover or switchback operation will be considered finished:

    1. Click Add and select Add switching detection to create a pair of conditions for switchover and switchback.

    2. Configure the conditions by clicking the underlined fields and selecting the appropriate values. The conditions can check whether an alarm exists, whether an element is in a particular state or whether a parameter has a particular value.

    3. If more conditions are necessary, click Add and configure the new conditions as described above.

  6. On the Views tab page, specify the view(s) where the redundancy group template should be created.

  7. Click the Create button in the lower right corner.
