    You’re running into VM-size availability or quota issues in the Azure portal (you see “Size not available” next to certain SKUs).

    Here’s what you can try:

    1. Check regional availability
      • In the portal, go to your VM > Settings > Size. Any size not listed (or marked “Size not available”) simply isn’t offered in that region for your subscription.
      • You can also run:
             az vm list-skus --location <your-region> --output table
        
        to see all SKUs available in that region.
    2. Review your quotas
      • In Azure Portal, search for “Usage + quotas” under your subscription or resource group and verify you haven’t hit a vCPU or core quota.
      • CLI:
             az vm list-usage --location <your-region> --output table
        
      • If you’re at quota, click “Request increase” or open a support request.
    3. Try an alternative size or region
      • If your desired size isn’t available, pick a different SKU in the same family or deploy in another nearby region.
      • When resizing an existing VM: stop the VM first (portal or az vm stop), change the size, then start it again.
    4. Troubleshoot allocation failures
      • Sometimes the cluster or availability set simply can’t allocate that size right now. Stopping all VMs in the set, then recreating or resizing can help.
      • Review allocation-failure guidance if you see errors like AllocationFailed.
    5. Use ARM templates or CLI for repeatable deployments
      • If you automate VM creation with ARM/CLI, you can programmatically check for available SKUs or fall back to an alternate size.
