Symptom & Impact

Replica initialization remains stalled, leaving DR targets outdated.

Environment & Reproduction

Occurs on WAN links with constrained throughput or certificate/auth mismatch.

Root Cause Analysis

Replication channel cannot sustain data transfer due to networking, authentication, or storage bottlenecks.

Quick Triage

Check replication health and event channels.

Get-WinEvent -LogName Microsoft-Windows-Hyper-V-VMMS-Admin -MaxEvents 50

Step-by-Step Diagnosis

Inspect replica broker, certificate trust, and queue depth.

Verification & Acceptance Criteria

Replica health reports Normal and RPO meets policy.

Rollback Plan

Disable replication and keep local backups active until recovery path is stable.

Disable-VMReplication -VMName App01

Prevention & Hardening

Monitor replication latency and reserve DR bandwidth during sync windows.
