Attaching an Amazon EBS Volume to an Instance

You can attach an available EBS volume to one of your instances that is in the same Availability Zone as the volume.

Prerequisites

  • Determine how many volumes you can attach to your instance. For more information, see Instance Volume Limits.

  • If a volume is encrypted, it can only be attached to an instance that supports Amazon EBS encryption. For more information, see Supported Instance Types.

  • If a volume has an AWS Marketplace product code:

    • The volume can only be attached to a stopped instance.

    • You must be subscribed to the AWS Marketplace code that is on the volume.

    • The configuration (instance type, operating system) of the instance must support that specific AWS Marketplace code. For example, you cannot take a volume from a Windows instance and attach it to a Linux instance.

    • AWS Marketplace product codes are copied from the volume to the instance.
