Unable to create Databricks Cluster despite increasing total region vCores to 128

Hi Rakesh P
Thank you for your question and for sharing details about the steps you've taken.

Based on the error message (Cloud Provider Resource Stockout: The VM size you are specifying is not available… SkuNotAvailable… Capacity Restrictions), the issue isn’t related to your subscription quota or regional vCores. Instead, it indicates that the requested VM size (Standard_DS3_v2) is temporarily out of stock in the East US region at the physical Azure datacenter level.

VM SKU stockouts are capacity issues - they occur when the requested VM size has no available physical hardware in the selected region. These are not affected by quota increases or vCore limits.

Workarounds:

• Try a different VM size (e.g., D2s_v5, D4s_v3, or another Databricks-supported SKU).
• Deploy in another region or availability zone (e.g., East US 2 or South Central US) where the SKU is available.
• Use the Azure CLI command

    az vm list-skus --location eastus --output table
  

  to check which VM sizes are currently available in your region.

Since this is a datacenter capacity constraint, it can’t be resolved by quota requests or Databricks settings. Only Microsoft’s infrastructure team can restore capacity, which usually takes time.

If you have critical workloads that require this specific SKU, you can contact Azure support for capacity planning options. However, switching VM size or region is typically the fastest solution.I hope this information helps. Please do let us know if you have any further queries.
