Failover steps for a disaster recovery event

  1. Stop services at the primary site. If possible, stop the services on all servers at the primary site.
  2. Failover all third-party services, such as:
    • Microsoft Active Directory
    • Microsoft Exchange
    • Skype for Business
    • Microsoft SharePoint
  3. Failover the databases:
    • BlackBerry UEM
       database
    • BEMS-Core
      1 database (
      BEMS-Mail
       cluster (
      Push Notifications
      ) database)
    • BEMS-Core
      2 database (
      BEMS-Presence
       cluster database)
    • BEMS-Core
      3 and Connect databases (
      BEMS-Connect
       cluster databases)
    • BEMS-Core
      4 and Docs databases (
      BEMS-Docs
       cluster databases)
  4. At the disaster recovery site, reconfigure the database access for the services to connect to the appropriate databases.
    • If the databases are using Always On Availability Groups for their disaster recovery configuration, then no action is required.
    • For configurations that do not use Always On Availability Groups, reconfigure the
      UEM Core
       database access by using the
      UEM
       Configuration Tool on each server to update the db.properties file.
  5. Start services at the disaster recovery site.
    Start the
    UEM Core
    ,
    BlackBerry Connectivity Node
    , and
    BlackBerry Proxy
     services first, then the
    BEMS
     services. You may need to enable the startup mode if it is disabled.
  6. Reconfigure the
    BEMS
     databases in the
    BEMS
     dashboard. Restart the
    BEMS
     services.
  7. Verify that the
    BlackBerry Presence
     and
    BlackBerry Connect
     services are stopped before you change the settings.
  8. For the
    BlackBerry Presence
     and
    BlackBerry Connect
     clusters, reconfigure the
    Lync
     front-end pool configuration. Restart the applicable services.
  9. For the
    BlackBerry Connect
     cluster,
    BEMS-Connect
     Service Configuration, reconfigure the
    BlackBerry Proxy
     startup server to point to the
    BlackBerry Proxy
     server at the disaster recovery site. Restart the applicable services.
  10. Reconfigure the network FQDN endpoints.
    Reconfigure the first FQDN (for example, cluster1.external.org.com) to point to an endpoint at the secondary site that has no
    BlackBerry Proxy
     servers attached. This is generally done through a Global Traffic Manager or equivalent and enables fast fail for attempted connections to the original primary site.
  11. Optionally, swap the primary and secondary servers.
    If the outage will be long-term, use the
    BlackBerry UEM
     console to swap the primary and secondary priorities for all App servers.
    Leave the
    BlackBerry Proxy
     configuration unchanged.
  12. To failback, follow steps 1 through 9, reversing the primary and disaster recovery sites.
