# Compute Cloud API, gRPC: DiskService.Get

Returns the specified Disk resource.
To get the list of available Disk resources, make a [List](list.md#List) request.

## gRPC request

**rpc Get ([GetDiskRequest](#yandex.cloud.compute.v1.GetDiskRequest)) returns ([Disk](#yandex.cloud.compute.v1.Disk))**

## GetDiskRequest {#yandex.cloud.compute.v1.GetDiskRequest}

```json
{
  "disk_id": "string"
}
```

#|
||Field | Description ||
|| disk_id | **string**

ID of the Disk resource to return.
To get the disk ID use a [DiskService.List](list.md#List) request.
The length must be less than or equal to 50.
This field is required. ||
|#

## Disk {#yandex.cloud.compute.v1.Disk}

```json
{
  "id": "string",
  "folder_id": "string",

    // end of the list of possible fields
  },
  "kms_key": {
    "key_id": "string",
    "version_id": "string"
  }
}
```

A Disk resource. For more information, see [Disks](../../../concepts/disk.md).

#|
||Field | Description ||
|| id | **string**

ID of the disk. ||
|| folder_id | **string**

ID of the folder that the disk belongs to. ||
|| created_at | **[google.protobuf.Timestamp](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#timestamp)** ||
|| name | **string**

Name of the disk. 1-63 characters long. ||
|| description | **string**

Description of the disk. 0-256 characters long. ||
|| labels | **object** (map<**string**, **string**>)

Resource labels as `key:value` pairs. Maximum of 64 per resource. ||
|| type_id | **string**

ID of the disk type. ||
|| zone_id | **string**

ID of the availability zone where the disk resides. ||
|| size | **int64**

Size of the disk, specified in bytes. ||
|| block_size | **int64**

Block size of the disk, specified in bytes. ||
|| product_ids[] | **string**

License IDs that indicate which licenses are attached to this resource.
License IDs are used to calculate additional charges for the use of the virtual machine.
The correct license ID is generated by the platform. IDs are inherited by new resources created from this resource.
If you know the license IDs, specify them when you create the image.
For example, if you create a disk image using a third-party utility and load it into Object Storage, the license IDs will be lost.
You can specify them in the [yandex.cloud.compute.v1.ImageService.Create](../Image/create.md#Create) request. ||
|| status | enum **Status**

Current status of the disk.

- `CREATING`: Disk is being created.
- `READY`: Disk is ready to use.
- `ERROR`: Disk encountered a problem and cannot operate.
- `DELETING`: Disk is being deleted. ||
|| source_image_id | **string**

ID of the image that was used for disk creation.

Includes only one of the fields `source_image_id`, `source_snapshot_id`. ||
|| source_snapshot_id | **string**

ID of the snapshot that was used for disk creation.

Includes only one of the fields `source_image_id`, `source_snapshot_id`. ||
|| instance_ids[] | **string**

Array of instances to which the disk is attached. ||
|| disk_placement_policy | **[DiskPlacementPolicy](#yandex.cloud.compute.v1.DiskPlacementPolicy)**

Placement policy configuration. ||
|| hardware_generation | **[HardwareGeneration](#yandex.cloud.compute.v1.HardwareGeneration)**

If specified, forces the same HardwareGeneration features to be applied to the instance
created using this disk as a boot one. Otherwise the current default will be used. ||
|| kms_key | **[KMSKey](#yandex.cloud.compute.v1.KMSKey)**

Key encryption key info. ||
|#

## DiskPlacementPolicy {#yandex.cloud.compute.v1.DiskPlacementPolicy}

#|
||Field | Description ||
|| placement_group_id | **string**

Placement group ID. ||
|| placement_group_partition | **int64** ||
|#

## HardwareGeneration {#yandex.cloud.compute.v1.HardwareGeneration}

A set of features, specific to a particular Compute hardware generation.
They are not necessary supported by every host OS or distro, thus they are fixed to an image
and are applied to all instances created with it as their boot disk image.
These features significantly determine how the instance is created, thus cannot be changed after the fact.

#|
||Field | Description ||
|| legacy_features | **[LegacyHardwareFeatures](#yandex.cloud.compute.v1.LegacyHardwareFeatures)**

Includes only one of the fields `legacy_features`, `generation2_features`. ||
|| generation2_features | **[Generation2HardwareFeatures](#yandex.cloud.compute.v1.Generation2HardwareFeatures)**

Includes only one of the fields `legacy_features`, `generation2_features`. ||
|#

## LegacyHardwareFeatures {#yandex.cloud.compute.v1.LegacyHardwareFeatures}

A first hardware generation, by default compatible with all legacy images.
Allows switching to PCI_TOPOLOGY_V2 and back.

#|
||Field | Description ||
|| pci_topology | enum **PCITopology**

- `PCI_TOPOLOGY_V1`
- `PCI_TOPOLOGY_V2` ||
|#

## Generation2HardwareFeatures {#yandex.cloud.compute.v1.Generation2HardwareFeatures}

A second hardware generation, which by default assumes PCI_TOPOLOGY_V2
and UEFI boot (with UEFI related features).

#|
||Field | Description ||
|| Empty | > ||
|#

## KMSKey {#yandex.cloud.compute.v1.KMSKey}

#|
||Field | Description ||
|| key_id | **string**

ID of KMS symmetric key ||
|| version_id | **string**

Version of KMS symmetric key ||
