Overview

Note:

When passing BlockDeviceMapping as input to an Aws::Client method, you can use a vanilla Hash:

{
  device_name: "String",
  virtual_name: "String",
  ebs: {
    delete_on_termination: false,
    iops: 1,
    snapshot_id: "String",
    volume_size: 1,
    volume_type: "standard", # accepts standard, io1, io2, gp2, sc1, st1
    kms_key_id: "String",
    encrypted: false,
  },
  no_device: "String",
}

Describes a block device mapping.

Instance Attribute Details

#device_name ⇒ String

The device name (for example, /dev/sdh or xvdh).

Returns:

  • (String) —

    The device name (for example, /dev/sdh or xvdh).

#ebs ⇒ Types::EbsBlockDevice

Parameters used to automatically set up EBS volumes when the instance is launched.

Returns:

  • (Types::EbsBlockDevice) —

    Parameters used to automatically set up EBS volumes when the instance is launched.

#no_device ⇒ String

Suppresses the specified device included in the block device mapping of the AMI.

Returns:

  • (String) —

    Suppresses the specified device included in the block device mapping of the AMI.

#virtual_name ⇒ String

The virtual device name (ephemeralN). Instance store volumes are numbered starting from 0. An instance type with 2 available instance store volumes can specify mappings for ephemeral0 and ephemeral1. The number of available instance store volumes depends on the instance type. After you connect to the instance, you must mount the volume.

NVMe instance store volumes are automatically enumerated and assigned a device name. Including them in your block device mapping has no effect.

Constraints: For M3 instances, you must specify instance store volumes in the block device mapping for the instance. When you launch an M3 instance, we ignore any instance store volumes specified in the block device mapping for the AMI.

Returns:

  • (String) —

    The virtual device name (ephemeralN).
