Question

Unable to create Azure Managed Redis in Central US or East US 2 region despite those regions are already available

Alyssa Vu 20 Microsoft Employee

I kept getting error saying the creation reached terminal state of "Failed" without any clear message about what caused the failure:

{
  "code": "DeploymentFailed",
  "target": "/subscriptions/xxx/resourceGroups/ray-example-rg/providers/Microsoft.Resources/deployments/CreateRedisEnterprise-ray-gcs-20260623172758",
  "message": "At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-deployment-operations for usage details.",
  "details": [
    {
      "code": "ResourceDeploymentFailure",
      "target": "/subscriptions/xxx/resourceGroups/ray-example-rg/providers/Microsoft.Cache/redisEnterprise/ray-gcs",
      "message": "The resource write operation failed to complete successfully, because it reached terminal provisioning state 'Failed'."
    }
  ]
}
