Constructor Details

DataDisk

public DataDisk()

Creates an instance of DataDisk class.

Method Details

caching

public CachingTypes caching()

Get the caching property: Specifies the caching requirements. Possible values are: **None,** **ReadOnly,** **ReadWrite.** The defaulting behavior is: **None for Standard storage. ReadOnly for Premium storage.**.

Returns:

the caching value.

createOption

public DiskCreateOptionTypes createOption()

Get the createOption property: 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 data disk. 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.

Returns:

the createOption value.

deleteOption

public DiskDeleteOptionTypes deleteOption()

Get the deleteOption property: Specifies whether data disk should be deleted or detached upon VM deletion. Possible values are: **Delete.** If this value is used, the data disk is deleted when VM is deleted. **Detach.** If this value is used, the data disk is retained after VM is deleted. The default value is set to **Detach**.

Returns:

the deleteOption value.

detachOption

public DiskDetachOptionTypes detachOption()

Get the detachOption property: 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: **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'.

Returns:

the detachOption value.

diskIopsReadWrite

public Long diskIopsReadWrite()

Get the diskIopsReadWrite property: Specifies the Read-Write IOPS for the managed disk when StorageAccountType is UltraSSD_LRS. Returned only for VirtualMachine ScaleSet VM disks. Can be updated only via updates to the VirtualMachine Scale Set.

Returns:

the diskIopsReadWrite value.

diskMBpsReadWrite

public Long diskMBpsReadWrite()

Get the diskMBpsReadWrite property: Specifies the bandwidth in MB per second for the managed disk when StorageAccountType is UltraSSD_LRS. Returned only for VirtualMachine ScaleSet VM disks. Can be updated only via updates to the VirtualMachine Scale Set.

Returns:

the diskMBpsReadWrite value.

diskSizeGB

public Integer diskSizeGB()

Get the diskSizeGB property: Specifies the size of an empty data disk in gigabytes. This element can be used to overwrite the size of the disk in a virtual machine image. The property 'diskSizeGB' is the number of bytes x 1024^3 for the disk and the value cannot be larger than 1023.

Returns:

the diskSizeGB value.

fromJson

public static DataDisk fromJson(JsonReader jsonReader)

Reads an instance of DataDisk from the JsonReader.

Get the managedDisk property: The managed disk parameters.

Returns:

the managedDisk value.
