Azure Center for SAP solutions service is a zone redundant service. So, service may experience downtime because no paired region exists. There will be no Microsoft initiated failover in the event of a region outage. This article explains some of the strategies that you can use to achieve cross-region resiliency for Virtual Instance for SAP solutions resources with customer enabled disaster recovery. It has detailed steps for you to follow when a region in which your Virtual Instance for SAP solutions resource exists is down.

| Case # | ACSS Service Region | SAP Workload Region | Scenario | Mitigation Steps |
26-
|--------|-----------------|------------------|--------------------------|------------------------|

| Case 1 | A (Down) | B | ACSS Service region is down | Register the workload with ACSS service available in another region using PowerShell or CLI which allow to select an available service location. |
28-
| Case 2 | A | B (Down) | SAP Workload region is down | 1. Customers should perform workload failover to DR region (outside of ACSS). <br> 2. Register the failed over workload with ACSS using PowerShell or CLI. |

| Case 3 | A (Down) | B (Down) | ACSS Service and SAP workload regions are down | 1. Customers should perform workload failover to DR region (outside of ACSS). <br> 2. Register the failed over workload with ACSS service available in another region using PowerShell or CLI which allow to select an available service location.

# Configure customer-enabled disaster recovery in Azure Center for SAP solutions
15+
16+
Azure Center for SAP solutions is a zone-redundant service. The service might experience downtime because no paired region exists, and there's no Microsoft-initiated failover during a region outage. This article explains strategies to achieve cross-region resiliency for Virtual Instance for SAP solutions resources with customer-enabled disaster recovery (DR). Also, steps to follow when a region where your Virtual Instance for SAP solutions resource exists is down.
17+
18+
You must configure disaster recovery for SAP systems that you deploy by using Azure Center for SAP solutions. For more information, see [Disaster recovery overview and infrastructure guidelines for SAP workload](/azure/sap/workloads/disaster-recovery-overview-guide).
19+
20+
When a region outage occurs, you're notified. The following sections describe the steps you can follow to get the Virtual Instance for SAP solutions resources running in a different region.
21+
22+
## Prerequisites
23+
24+
- An SAP system deployed by using Azure Center for SAP solutions or registered with Azure Center for SAP solutions.
25+
- DR configured for your SAP system by using the [Disaster recovery overview and infrastructure guidelines for SAP workload](/azure/sap/workloads/disaster-recovery-overview-guide).

## Understand region-down scenarios and mitigation steps
28+
29+
| Case | Service region | Workload region | Scenario | Mitigation steps |
30+
|------|----------------|-----------------|----------|------------------|
31+
| 1 | A (down) | B | Azure Center for SAP solutions service region is down. | Register the workload with an Azure Center for SAP solutions service available in another region by using PowerShell or CLI, which allow you to select an available service location. |
32+
| 2 | A | B (down) | SAP workload region is down. | 1. Perform workload failover to the DR region (outside of Azure Center for SAP solutions). <br><br> 2. Register the failed-over workload by using PowerShell or CLI. |
33+
| 3 | A (down) | B (down) | Both the service and SAP workload regions are down. | 1. Perform workload failover to the DR region (outside of Azure Center for SAP solutions). <br><br> 2. Register the failed-over workload with an Azure Center for SAP solutions service available in another region by using PowerShell or CLI. |
34+
35+
## Re-register the SAP system during a regional outage
36+
37+
1. If the region where your SAP workload exists is down (cases 1 and 2), perform workload failover to the DR region outside of Azure Center for SAP solutions and have the workload running in a secondary region.
38+
39+
1. If the Azure Center for SAP solutions service is down (cases 1 and 3) in the region where your Virtual Instance for SAP solutions resource exists, register your SAP system with another available region.
