2.1 Complete Connectivity Loss of Primary SDS NOAM Servers

Pre Condition

• User cannot access Primary SDS site GUI
• User can access DR SDS GUI
• Provisioning clients are disconnected from the primary SDS
• Provisioning has stopped

Recovery Procedure

To make SDS GUI accessible and provisioning to continue, perform the following procedure:

1. Promoting the DR NOAM from secondary to primary as described in DSR and SDS NOAM Failover User's Guide.
2. Recover primary NOAM as DRNO as described in DSR and SDS NOAM Failover User's Guide.

   Note:

   The Active Network server allows SNMP administration. Global SNMP configuration cannot be modified if DR site is made primary. It can be updated when original site becomes primary.

Post Condition

• GUI on the new Primary SDS is accessible
• Provisioning clients are connected to the new Primary SDS
• Database provisioning resumes
• A new DR SDS GUI is accessible
• Replication and collection alarms have cleared

  Note:

  To swap new primary SDS and new DR SDS sites back to their original roles, perform Step 8 on new-Primary SDS (old-DR SDS) and Step 2 on new-DR SDS (old-Primary SDS) from Procedure 1 (Demoting the Active NOAM from Primary to Secondary) in DSR and SDS NOAM Failover User's Guide.
