Attaches an EBS volume to a running or stopped instance and exposes it to the instance with the specified device name.
Encrypted EBS volumes may only be attached to instances that support Amazon EBS encryption. For more information, see Amazon EBS Encryption in the Amazon Elastic Compute Cloud User Guide.
For a list of supported device names, see Attaching an EBS Volume to an Instance. Any device names that aren't reserved for instance store volumes can be used for EBS volumes. For more information, see Amazon EC2 Instance Store in the Amazon Elastic Compute Cloud User Guide.
If a volume has an AWS Marketplace product code:

AWS Marketplace product codes are copied from the volume to the instance.
You must be subscribed to the product.
The instance type and operating system of the instance must support the product. For example, you can't detach a volume from a Windows instance and attach it to a Linux instance.
