Task 05: Verify Azure Arc Connectivity
DOCUMENT CATEGORY: Runbook SCOPE: Azure Arc verification PURPOSE: Confirm provisioned machines are Arc-connected and ready for cluster deployment MASTER REFERENCE: Microsoft Learn — Simplified Machine Provisioning
Status: Active
Overview
After provisioning completes, verify that all machines are connected to Azure Arc and show a "Ready to cluster" status. This confirms the machines are ready for Phase 05: Cluster Deployment.
When using simplified provisioning, Azure Arc registration is handled automatically during the provisioning process. You do not need to complete Phase 04: Arc Registration separately — it was done as part of the provisioning flow.
Step-by-Step
Step 1: Check Provisioned Machine Status in Azure Portal
- In the Azure portal, navigate to Azure Arc → Operations → Provisioning (preview)
- Select the Provisioned machines tab
- Locate your machines in the list
- Verify each machine's status shows "Ready to cluster"
Step 2: Verify Arc Resource Details
For each machine, select the machine name to view detailed status:
| Check | Expected Value |
|---|---|
| Status | Ready to cluster |
| Azure Arc status | Connected |
| OS | Azure Stack HCI |
| Extensions | All mandatory extensions installed |
Step 3: Verify via Azure CLI (Optional)
# List Arc-connected machines in the resource group
az connectedmachine list \
--resource-group <resource-group-name> \
--query "[].{Name:name, Status:status, OS:osName}" \
-o table
Expected output: all machines show Connected status with Azure Stack HCI OS.
Validation
- All machines show "Ready to cluster" in the provisioning portal
- All machines show Connected in Azure Arc
- All mandatory Azure Arc extensions are installed
- Machine names match the Arc resource names configured in Task 03
Next Steps
With all machines verified:
- If using ISO-based installation, you would continue to Phase 03: OS Configuration and then Phase 04: Arc Registration
- With simplified provisioning, OS configuration and Arc registration are already done — proceed directly to Phase 05: Cluster Deployment
Troubleshooting
| Issue | Resolution |
|---|---|
| Machine status not "Ready to cluster" | Check the machine's detailed status for error messages. Common causes: network connectivity issues, DNS resolution failures, or extension installation failures. |
| Machine shows "Disconnected" in Azure Arc | Verify the machine has outbound internet access. Check firewall rules for required Azure Arc endpoints. Power cycle the machine if needed. |
| Missing Arc extensions | Extensions install automatically. Wait a few minutes and refresh. If still missing, check the machine's extension status in Azure Arc for error details. |
| Machine not visible in provisioning portal | Verify the voucher was uploaded correctly in Task 03. Ensure the machine is in the correct resource group. |
