Issue/Introduction

Environment

• VMware Live Recovery 9.1

Resolution

Q: What does the 'Replication - configuration health' check do? 

• This check monitors the configuration integrity of virtual machines within protection groups.
• It validates critical parameters required for successful replication, including licensing, replica seeding, datastores settings and other configuration parameters.

Q: What does it mean when it is in an error state?

• An error state indicates a configuration mismatch or a resource constraint that prevents the replication engine from operating as intended.
• If these issues are not addressed, it could prevent replication or cause RPO violation.

Q: How does one troubleshoot and fix the error state?

• To resolve configuration-related issues, follow these steps:

1. 1. Identify Impacted VMs: View the VM list within the specific Protection Group. Look for status icons or specific error messages tied to individual virtual machines to narrow down the root cause.
   2. Verify Licensing: Ensure that both the source and target sites have valid licenses that support the current replication frequency and features.
