Instance Attribute Details

#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 for Linux Instances*.

<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.

  :device_name,
  :ebs,
  :no_device)
  SENSITIVE = []
  include Aws::Structure
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.

Returns:

  • (Boolean)

#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`.
