Definitions

Name	Description
ApiEntityReference	The API entity reference.
ApiError	Api error.
ApiErrorBase	Api error base.
AttachDetachDataDisksRequest	Specifies the input for attaching and detaching a list of managed data disks.
CachingTypes	Specifies the caching requirements. Possible values are: None, ReadOnly, ReadWrite. The default values are: None for Standard storage. ReadOnly for Premium storage
CloudError	An error response from the Compute service.
DataDisk	Describes a data disk.
DataDisksToAttach	Describes the data disk to be attached.
DataDisksToDetach	Describes the data disk to be detached.
DiffDiskOptions	Specifies the ephemeral disk option for operating system disk.
DiffDiskPlacement	Specifies the ephemeral disk placement for operating system disk. This property can be used by user in the request to choose the location i.e, cache disk, resource disk or nvme disk space for Ephemeral OS disk provisioning. For more information on Ephemeral OS disk size requirements, please refer Ephemeral OS disk size requirements for Windows VM at https://docs.microsoft.com/azure/virtual-machines/windows/ephemeral-os-disks#size-requirements and Linux VM at https://docs.microsoft.com/azure/virtual-machines/linux/ephemeral-os-disks#size-requirements. Minimum api-version for NvmeDisk: 2024-03-01.
DiffDiskSettings	Describes the parameters of ephemeral disk settings that can be specified for operating system disk. Note: The ephemeral disk settings can only be specified for managed disk.
DiskControllerTypes	Specifies the disk controller type configured for the VM and VirtualMachineScaleSet. This property is only supported for virtual machines whose operating system disk and VM sku supports Generation 2 (https://docs.microsoft.com/en-us/azure/virtual-machines/generation-2), please check the HyperVGenerations capability returned as part of VM sku capabilities in the response of Microsoft.Compute SKUs api for the region contains V2 (https://docs.microsoft.com/rest/api/compute/resourceskus/list). For more information about Disk Controller Types supported please refer to https://aka.ms/azure-diskcontrollertypes.
DiskCreateOptionTypes	Specifies how the virtual machine disk should be created. Possible values are Attach: This value is used when you are using a specialized disk to create the virtual machine. FromImage: This value is used when you are using an image to create the virtual machine. If you are using a platform image, you should also use the imageReference element described above. If you are using a marketplace image, you should also use the plan element previously described. Empty: This value is used when creating an empty data disk. Copy: This value is used to create a data disk from a snapshot or another disk. Restore: This value is used to create a data disk from a disk restore point.
DiskDeleteOptionTypes	Specifies the behavior of the managed disk when the VM gets deleted, for example whether the managed disk is deleted or detached. Supported values are: Delete. If this value is used, the managed disk is deleted when VM gets deleted. Detach. If this value is used, the managed disk is retained after VM gets deleted. Minimum api-version: 2021-03-01.
DiskDetachOptionTypes	Specifies the detach behavior to be used while detaching a disk or which is already in the process of detachment from the virtual machine. Supported values are: ForceDetach. detachOption: ForceDetach is applicable only for managed data disks. If a previous detachment attempt of the data disk did not complete due to an unexpected failure from the virtual machine and the disk is still not released then use force-detach as a last resort option to detach the disk forcibly from the VM. All writes might not have been flushed when using this detach behavior. This feature is still in preview. To force-detach a data disk update toBeDetached to 'true' along with setting detachOption: 'ForceDetach'.
DiskEncryptionSetParameters	Describes the parameter of customer managed disk encryption set resource id that can be specified for disk. Note: The disk encryption set resource id can only be specified for managed disk. Please refer https://aka.ms/mdssewithcmkoverview for more details.
DiskEncryptionSettings	Describes a Encryption Settings for a Disk
ImageReference	Specifies information about the image to use. You can specify information about platform images, marketplace images, or virtual machine images. This element is required when you want to use a platform image, marketplace image, or virtual machine image, but is not used in other creation operations. NOTE: Image reference publisher and offer can only be set when you create the scale set.
InnerError	Inner error details.
KeyVaultKeyReference	Describes a reference to Key Vault Key
KeyVaultSecretReference	Describes a reference to Key Vault Secret
ManagedDiskParameters	The parameters of a managed disk.
OperatingSystemTypes	This property allows you to specify the type of the OS that is included in the disk if creating a VM from user-image or a specialized VHD. Possible values are: Windows, Linux.
OSDisk	Specifies information about the operating system disk used by the virtual machine. For more information about disks, see About disks and VHDs for Azure virtual machines.
SecurityEncryptionTypes	Specifies the EncryptionType of the managed disk. It is set to DiskWithVMGuestState for encryption of the managed disk along with VMGuestState blob, VMGuestStateOnly for encryption of just the VMGuestState blob, and NonPersistedTPM for not persisting firmware state in the VMGuestState blob.. Note: It can be set for only Confidential VMs.
StorageAccountTypes	Specifies the storage account type for the managed disk. Managed OS disk storage account type can only be set when you create the scale set. NOTE: UltraSSD_LRS can only be used with data disks. It cannot be used with OS Disk. Standard_LRS uses Standard HDD. StandardSSD_LRS uses Standard SSD. Premium_LRS uses Premium SSD. UltraSSD_LRS uses Ultra disk. Premium_ZRS uses Premium SSD zone redundant storage. StandardSSD_ZRS uses Standard SSD zone redundant storage. For more information regarding disks supported for Windows Virtual Machines, refer to https://docs.microsoft.com/azure/virtual-machines/windows/disks-types and, for Linux Virtual Machines, refer to https://docs.microsoft.com/azure/virtual-machines/linux/disks-types
StorageProfile	Specifies the storage settings for the virtual machine disks.
SubResource
VirtualHardDisk	Describes the uri of a disk.
VMDiskSecurityProfile	Specifies the security profile settings for the managed disk. Note: It can only be set for Confidential VMs.
