AWSEC2BlockDeviceMapping

Objective-C

@interface AWSEC2BlockDeviceMapping

Swift

class AWSEC2BlockDeviceMapping

Describes a block device mapping.

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

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable deviceName;

    Swift

    var deviceName: String? { get set }
  • ebs

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

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2EbsBlockDevice *_Nullable ebs;

    Swift

    var ebs: AWSEC2EbsBlockDevice? { get set }
  • Suppresses the specified device included in the block device mapping of the AMI.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable noDevice;

    Swift

    var noDevice: String? { get set }
  • 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.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable virtualName;

    Swift

    var virtualName: String? { get set }
