Planned switchback from DC2 to DC1

Last Updated : Mar 29, 2023 |

This chapter provides information and instructions to take DC2 out of production and into a shutdown or standby mode to perform a switchback to DC1.

Switchback from planned maintenance windows

After planned partial or full switchovers to the DR site, implement a planned switchback to re-instate the primary site as the operational data center. However, due to the licensing restrictions with ESS, the disaster recovery at the DR site functions only for a limited time.

Switchback from Full DR Switchover

When you re-instate DC1, ensure that the data in Avaya Aura® System Manager and Avaya Control Manager is aligned with the data in Avaya Aura® Communication Manager. The administrative changes from DC2 are not present on Avaya Aura® Communication Manager in DC1, so Avaya Aura® System Manager and Avaya Control Manager must have data corresponding to Avaya Aura® Communication Manager before the switchback to DC1.

Switchback from Partial DR Switchover

In a partial switchover, Avaya Aura® System Manager, Avaya Aura® Communication Manager, and Avaya Control Manager are not switched from the primary site to the DR site.

When you re-instate the primary site, the Avaya Aura® System Manager and Avaya Control Manager are aligned with the data on Avaya Aura® Communication Manager.

Note:

You need a maintenance window to perform the recovery regardless of the switchover option. During this maintenance window, Avaya Oceana® cannot process any contacts. For example, if the contact center needs to process voice contacts during the maintenance window, it is recommended to use the fallback to Elite feature that gets automatically invoked once Avaya Oceana® is out of service. There is no fallback alternative for Digital Contacts.

Advantages of performing a planned switchback

Planned maintenance windows are defined as customer-agreed time periods where the deployed solution is taken out of production and put into a shutdown or standby mode to perform a switchover and a switchback between the two parts of the DR solution.

There are several advantages of performing a planned switchback of Avaya Oceana® and Avaya Analytics™ DR solution.

  • Existing contacts can be processed in a controlled manner.

  • New contacts cannot enter into the system queue after the switchover procedures start.

  • Logged-in agents can access the currently queued contacts.

  • All contacts can be cleared before the shutdown of either side of the DR system, primary or DR.

  • Supervisor users logged in using Avaya Workspaces can view real-time reports and displays to ensure a graceful shutdown of all existing contacts.
