:CreateDisk

The operation that you want to perform. Set the value to CreateDisk.

The ID of the region in which to create the data disk. You can call the DescribeRegions operation to query the most recent region list.

The ID of the snapshot to use to create the disk. Snapshots that were created on or before July 15, 2013 cannot be used to create disks.

The following limits apply to the SnapshotId and Size parameters:

• If the size of the snapshot specified by the SnapshotId parameter is larger than the value of the Size parameter, the size of the created disk is equal to the specified snapshot size.
• If the size of the snapshot specified by the SnapshotId parameter is smaller than the value of the Size parameter, the size of the created disk is equal to the value of Size.

The name of the disk. The name must be 2 to 128 characters in length. The name must start with a letter and cannot start with http:// or https://. The name can contain letters, digits, colons (:), underscores (_), and hyphens (-).

This parameter is empty by default.

The size of the disk. Unit: GiB. This parameter is required. Valid values:

• Valid values when DiskCategory is set to cloud: 5 to 2000.
• Valid values when DiskCategory is set to cloud_efficiency: 20 to 32768.
• Valid values when DiskCategory is set to cloud_ssd: 20 to 32768.
• Valid values when DiskCategory is set to cloud_essd: depend on the PerformanceLevel value.
  • Valid values when PerformanceLevel is set to PL0: 40 to 32768.
  • Valid values when PerformanceLevel is set to PL1: 20 to 32768.
  • Valid values when PerformanceLevel is set to PL2: 461 to 32768.
  • Valid values when PerformanceLevel is set to PL3: 1261 to 32768.
• Valid values when DiskCategory is set to cloud_auto: 40 to 32768.
• Valid values when DiskCategory is set to cloud_essd_entry: 10 to 32768.

If the SnapshotId parameter is specified, the following limits apply to the SnapshotId and Size parameters:

• If the size of the snapshot specified by the SnapshotId parameter is larger than the value of the Size parameter, the size of the created disk is equal to the specified snapshot size.
• If the size of the snapshot specified by the SnapshotId parameter is smaller than the value of the Size parameter, the size of the created disk is equal to the value of the Size parameter.

The category of the data disk. Valid values:

• cloud: basic disk
• cloud_efficiency: ultra disk
• cloud_ssd: standard SSD
• cloud_essd: ESSD
• cloud_auto: ESSD AutoPL disk
• cloud_essd_entry: ESSD Entry disk

Default value: cloud.

The description of the disk. The description must be 2 to 256 characters in length and cannot start with http:// or https://.

This parameter is empty by default.

Specifies whether to encrypt the disk. Valid values:

• true
• false

Default value: false.

The client token that is used to ensure the idempotence of the request. You can use the client to generate the token, but you must make sure that the token is unique among different requests. The token can contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence.

The ID of the instance to which to attach the created subscription disk.

• After you specify this parameter, ResourceGroupId, Tag.N.Key, Tag.N.Value, ClientToken, and KMSKeyId are ignored.
• You cannot specify ZoneId and InstanceId at the same time.

This parameter is empty by default. This indicates that a pay-as-you-go disk is created, and the RegionId and ZoneId parameters specify where the disk resides.

The ID of the resource group to which to assign the disk.

The ID of the Key Management Service (KMS) key to use for the disk.

The performance level of the ESSD. Valid values:

• PL0: A single ESSD can deliver up to 10000 random read/write IOPS.
• PL1: A single ESSD can deliver up to 50000 random read/write IOPS.
• PL2: A single ESSD can deliver up to 100000 random read/write IOPS.
• PL3: A single ESSD can deliver up to 1000000 random read/write IOPS.

Default value: PL1.

For information about ESSD performance levels, see ESSDs.

This parameter is not publicly available.

The ID of the storage set.

This parameter is not publicly available.

The number of partitions in the storage set. The value must be greater than or equal to 2 but cannot exceed the quota obtained by calling the DescribeAccountAttributes operation.

Default value: 2.

The ID of the dedicated block storage cluster. To create a disk in a specific dedicated block storage cluster, you must specify this parameter.

Specifies whether to enable the multi-attach feature for the disk. Valid values:

• Disabled
• Enabled Set the value to Enabled only for ESSDs.

Default value: Disabled.
