Add instance store volumes to an EC2 instance during launch - Amazon Elastic Compute Cloud

Add instance store volumes to an EC2 instance during launch

When you launch an instance type with non-NVMe instance store volumes, such as C1, C3, M1, M2, M3, R3, D2, H1, I2, X1, and X1e, you must specify the block device mappings for the instance store volumes that you want to attach at launch. The block device mappings must be specified in the instance launch request or in the AMI used to launch the instance.

If the AMI includes block device mappings for the instance store volumes, you do not need to specify block device mappings in the instance launch request, unless you need more instance store volumes than is included in the AMI.

If the AMI does not include block device mappings for instance store volumes, then you must specify the block device mappings in the instance launch request.

For instance types with NVMe instance store volumes, all of the supported instance store volumes are automatically attached to the instance at launch.

Considerations

  • For M3 instances, you might receive instance store volumes even if you do not specify them in the block device mapping for the instance.

To specify block device mappings in the instance launch request, use one of the following methods.

Amazon EC2 console

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

  2. From the dashboard, choose Launch instance.

  3. In the Application and OS Images section, select the AMI to use.

  4. In the Configure storage section, the Instance store volumes section lists the instance store volumes that can be attached to the instance. The number of available instance store volumes depends on the instance type.

  5. For each instance store volume to attach, for Device name, select the device name to use.

  6. Configure the remaining instance settings as needed, and then choose Launch instance.

Command line

You can use one of the following options commands with the corresponding option.
