Canceling Azure SQL Managed Instance management operations
Applies to: Azure SQL Managed Instance
Azure SQL Managed Instance provides the ability to cancel some management operations, such as when you deploy a new managed instance or update instance properties.
All management operations can be categorized as follows:
- Instance deployment (new instance creation).
- Instance update (changing instance properties, such as vCores or reserved storage).
- Instance deletion.
You can monitor progress and status of management operations and cancel some of them if necessary.
The following table summarizes management operations, whether or not you can cancel them, and their typical overall duration:
|Category||Operation||Cancelable||Estimated cancel duration|
|Deployment||Instance creation||Yes||90% of operations finish in 5 minutes.|
|Update||Instance storage scaling up/down (General Purpose)||No|
|Update||Instance storage scaling up/down (Business Critical)||Yes||90% of operations finish in 5 minutes.|
|Update||Instance compute (vCores) scaling up and down (General Purpose)||Yes||90% of operations finish in 5 minutes.|
|Update||Instance compute (vCores) scaling up and down (Business Critical)||Yes||90% of operations finish in 5 minutes.|
|Update||Instance service tier change (General Purpose to Business Critical and vice versa)||Yes||90% of operations finish in 5 minutes.|
|Delete||Virtual cluster deletion (as user-initiated operation)||No|
Cancel management operation
To cancel management operations using the Azure portal, follow these steps:
Go to the Azure portal
Go to the Overview blade of your SQL Managed Instance.
Select the Notification box next to the ongoing operation to open the Ongoing Operation page.
Select Cancel the operation at the bottom of the page.
Confirm that you want to cancel the operation.
If the cancel request succeeds, the management operation is canceled and results in a failure. You will get a notification that the cancellation succeeds or fails.
If the cancel request fails or the cancel button is not active, it means that the management operation has entered non-cancelable state and that will finish shortly. The management operation will continue its execution until it is completed.
Canceled deployment request
With API version 2020-02-02, as soon as the instance creation request is accepted, the instance starts to exist as a resource, no matter the progress of the deployment process (managed instance status is Provisioning). If you cancel the instance deployment request (new instance creation), the managed instance will go from the Provisioning state to FailedToCreate.
Instances that have failed to create are still present as a resource and:
- Are not charged
- Do not count towards resource limits (subnet or vCore quota)
To minimize noise in the the list of resources or managed instances, delete instances that have failed to deploy or instances with cancelled deployments.
