#device_name ⇒ String

The device name assigned to the volume (for example, /dev/sdh or xvdh). For more information, see [Device naming on Linux instances] in the *Amazon EC2 User Guide*.

<note markdown=“1”> To define a block device mapping, set the device name and exactly one of the following properties: Ebs, NoDevice, or VirtualName.

#ebs ⇒ Types::Ebs

Information to attach an EBS volume to an instance at launch.

end

#no_device ⇒ Boolean

Setting this value to true prevents a volume that is included in the block device mapping of the AMI from being mapped to the specified device name at launch.

If NoDevice is true for the root device, instances might fail the EC2 health check. In that case, Amazon EC2 Auto Scaling launches replacement instances.

end

#virtual_name ⇒ String

The name of the instance store volume (virtual device) to attach to an instance at launch. The name must be in the form ephemeral*X* where X is a number starting from zero (0), for example, ephemeral0.
