Effect
Replication failures will prevent the successful failover of your system from it’s primary region to a secondary region in the case of outages in the primary region requiring failover.
Fixes
The fix to a replication issue depends on the underlying cause of the problem. There are many issues that can cause replication failures, like:
- Replication causes resource utilization above the allotted quotas
- Missing root certificates required for authorization of recovery services
- DNS-related connectivity issues
- Disks are unavailable for replication
To troubleshoot the issue:
- Go to Recovery Services vaults on the Azure Portal
- Select the vault that is reported to have issues
- Select Replicated Items
- Find the items with an unhealthy replication state and click the reported state
This should take you to a page with more details regarding the error and a recommendation for what to do to resolve it.
