createOption	This enumerates the possible sources of a disk's creation.	'Attach' 'Copy' 'CopyFromSanSnapshot' 'CopyStart' 'Empty' 'FromImage' 'Import' 'ImportSecure' 'Restore' 'Upload' 'UploadPreparedSecure' (required)
elasticSanResourceId	Required if createOption is CopyFromSanSnapshot. This is the ARM id of the source elastic san volume snapshot.	string
galleryImageReference	Required if creating from a Gallery Image. The id/sharedGalleryImageId/communityGalleryImageId of the ImageDiskReference will be the ARM id of the shared galley image version from which to create a disk.	ImageDiskReference
imageReference	Disk source information for PIR or user images.	ImageDiskReference
logicalSectorSize	Logical sector size in bytes for Ultra disks. Supported values are 512 ad 4096. 4096 is the default.	int
performancePlus	Set this flag to true to get a boost on the performance target of the disk deployed, see here on the respective performance target. This flag can only be set on disk creation time and cannot be disabled after enabled.	bool
provisionedBandwidthCopySpeed	If this field is set on a snapshot and createOption is CopyStart, the snapshot will be copied at a quicker speed.	'Enhanced' 'None'
securityDataUri	If createOption is ImportSecure, this is the URI of a blob to be imported into VM guest state.	string
sourceResourceId	If createOption is Copy, this is the ARM id of the source snapshot or disk.	string
sourceUri	If createOption is Import, this is the URI of a blob to be imported into a managed disk.	string
storageAccountId	Required if createOption is Import. The Azure Resource Manager identifier of the storage account containing the blob to import as a disk.	string
uploadSizeBytes	If createOption is Upload, this is the size of the contents of the upload including the VHD footer. This value should be between 20972032 (20 MiB + 512 bytes for the VHD footer) and 35183298347520 bytes (32 TiB + 512 bytes for the VHD footer).	int

DiskProperties

Name	Description	Value
burstingEnabled	Set to true to enable bursting beyond the provisioned performance target of the disk. Bursting is disabled by default. Does not apply to Ultra disks.	bool
completionPercent	Percentage complete for the background copy when a resource is created via the CopyStart operation.	int
creationData	Disk source information. CreationData information cannot be changed after the disk has been created.	CreationData (required)
dataAccessAuthMode	Additional authentication requirements when exporting or uploading to a disk or snapshot.	'AzureActiveDirectory' 'None'
diskAccessId	ARM id of the DiskAccess resource for using private endpoints on disks.	string
diskIOPSReadOnly	The total number of IOPS that will be allowed across all VMs mounting the shared disk as ReadOnly. One operation can transfer between 4k and 256k bytes.	int
diskIOPSReadWrite	The number of IOPS allowed for this disk; only settable for UltraSSD disks. One operation can transfer between 4k and 256k bytes.	int
diskMBpsReadOnly	The total throughput (MBps) that will be allowed across all VMs mounting the shared disk as ReadOnly. MBps means millions of bytes per second - MB here uses the ISO notation, of powers of 10.	int
diskMBpsReadWrite	The bandwidth allowed for this disk; only settable for UltraSSD disks. MBps means millions of bytes per second - MB here uses the ISO notation, of powers of 10.	int
diskSizeGB	If creationData.createOption is Empty, this field is mandatory and it indicates the size of the disk to create. If this field is present for updates or creation with other options, it indicates a resize. Resizes are only allowed if the disk is not attached to a running VM, and can only increase the disk's size.	int
encryption	Encryption property can be used to encrypt data at rest with customer managed keys or platform managed keys.	Encryption
encryptionSettingsCollection	Encryption settings collection used for Azure Disk Encryption, can contain multiple encryption settings per disk or snapshot.	EncryptionSettingsCollection
hyperVGeneration	The hypervisor generation of the Virtual Machine. Applicable to OS disks only.	'V1' 'V2'
maxShares	The maximum number of VMs that can attach to the disk at the same time. Value greater than one indicates a disk that can be mounted on multiple VMs at the same time.	int
networkAccessPolicy	Policy for accessing the disk via network.	'AllowAll' 'AllowPrivate' 'DenyAll'
optimizedForFrequentAttach	Setting this property to true improves reliability and performance of data disks that are frequently (more than 5 times a day) by detached from one virtual machine and attached to another. This property should not be set for disks that are not detached and attached frequently as it causes the disks to not align with the fault domain of the virtual machine.	bool
osType	The Operating System type.	'Linux' 'Windows'
publicNetworkAccess	Policy for controlling export on the disk.	'Disabled' 'Enabled'
purchasePlan	Purchase plan information for the the image from which the OS disk was created. E.g. - {name: 2019-Datacenter, publisher: MicrosoftWindowsServer, product: WindowsServer}	PurchasePlan
