Symptom & Impact

CSV traffic routes through network redirect path, causing major I/O latency and VM performance degradation.

Environment & Reproduction

Appears after storage path interruption or cluster network instability.

Get-ClusterSharedVolume | fl Name,State
Get-ClusterSharedVolumeState

Root Cause Analysis

CSV ownership/path health checks fail, so cluster keeps redirected I/O mode for data safety.

Quick Triage

Validate storage connectivity and cluster network heartbeat quality.

Get-ClusterNetwork
Get-MPIOAvailableHW

Step-by-Step Diagnosis

Review failover clustering and storage stack events around transition time.

Get-WinEvent -LogName System -MaxEvents 300 | ? {$_.ProviderName -match 'FailoverClustering|storport|disk'}

Solution – Primary Fix

Restore healthy storage path and force CSV back to direct mode.

Resume-ClusterResource -Name 
Move-ClusterSharedVolume -Name 

Solution – Alternative Approaches

Drain node and patch HBA/NIC firmware if path instability persists.

Verification & Acceptance Criteria

CSV returns to direct mode and baseline latency/throughput metrics normalize.

Rollback Plan

If direct mode causes instability, revert to maintenance state and fail workloads to healthy nodes.

Prevention & Hardening

Implement path redundancy testing and proactive firmware lifecycle governance.

Related Errors & Cross-Refs

Commonly linked with Event ID 5120 and intermittent SMB Direct transport resets.
