AWSEC2ModifyVolumeRequest

Objective-C

@interface AWSEC2ModifyVolumeRequest

Swift

class AWSEC2ModifyVolumeRequest

  • Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable dryRun;

    Swift

    var dryRun: NSNumber? { get set }

  • The target IOPS rate of the volume. This parameter is valid only for gp3, io1, and io2 volumes.

    The following are the supported values for each volume type:

    • gp3: 3,000 - 16,000 IOPS

    • io1: 100 - 64,000 IOPS

    • io2: 100 - 256,000 IOPS

    For io2 volumes, you can achieve up to 256,000 IOPS on instances built on the Nitro System. On other instances, you can achieve performance up to 32,000 IOPS.

    Default: The existing value is retained if you keep the same volume type. If you change the volume type to io1, io2, or gp3, the default is 3,000.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable iops;

    Swift

    var iops: NSNumber? { get set }

  • Specifies whether to enable Amazon EBS Multi-Attach. If you enable Multi-Attach, you can attach the volume to up to 16 Nitro-based instances in the same Availability Zone. This parameter is supported with io1 and io2 volumes only. For more information, see Amazon EBS Multi-Attach in the Amazon EBS User Guide.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable multiAttachEnabled;

    Swift

    var multiAttachEnabled: NSNumber? { get set }

  • The target size of the volume, in GiB. The target volume size must be greater than or equal to the existing size of the volume.

    The following are the supported volumes sizes for each volume type:

    • gp2 and gp3: 1 - 16,384 GiB

    • io1: 4 - 16,384 GiB

    • io2: 4 - 65,536 GiB

    • st1 and sc1: 125 - 16,384 GiB

    • standard: 1 - 1024 GiB

    Default: The existing size is retained.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable size;

    Swift

    var size: NSNumber? { get set }

  • The target throughput of the volume, in MiB/s. This parameter is valid only for gp3 volumes. The maximum value is 1,000.

    Default: The existing value is retained if the source and target volume type is gp3. Otherwise, the default value is 125.

    Valid Range: Minimum value of 125. Maximum value of 1000.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable throughput;

    Swift

    var throughput: NSNumber? { get set }

  • The ID of the volume.

    Declaration

    Objective-C

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

    Swift

    var volumeId: String? { get set }

  • The target EBS volume type of the volume. For more information, see Amazon EBS volume types in the Amazon EBS User Guide.

    Default: The existing type is retained.

    Declaration

    Objective-C

    @property (nonatomic) AWSEC2VolumeType volumeType;

    Swift

    var volumeType: AWSEC2VolumeType { get set }
