• roleInstanceName
  Type: System.String

  The name of the role instance that should be reimaged.

• cancellationToken
  Type: System.Threading.CancellationToken

  The cancellation token.

Return Value

Type: System.Threading.Tasks.Task<OperationStatusResponse>

The T:Microsoft.WindowsAzure.Management.Compute.Models.ComputeOperationStatusResponse object that contains the status of the operation.

Remarks

If the asynchronous operation succeeds, the response includes the HTTP status code for the successful request. If the asynchronous operation failed, the response includes the HTTP status code for the failed request, and also includes error information about the failure.

For more information about reimaging a role instance, see Reimage Role Instance.

When the role instance is reimaged, the instance is taken offline and a fresh guest operating system image is applied. The role instance is then brought back online. Azure attempts to maintain data in any local storage resources when the role is reimaged; however, in case of a transient hardware failure, the local storage resource may be lost. If your application requires that this data be persisted, it is recommended that you write it to a durable data source, such as an Azure drive. Any data that is written to a local directory other than that defined by the local storage resource will be lost when the role is reimaged.
