DataDisk interface
Describes a data disk.
Properties
| caching | Specifies the caching requirements. |
| create |
Specifies how the virtual machine should be created. |
| delete |
Specifies whether data disk should be deleted or detached upon VM deletion. |
| detach |
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. |
| disk |
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. |
| image | The source user image virtual hard disk. The virtual hard disk will be copied before being attached to the virtual machine. If SourceImage is provided, the destination virtual hard drive must not exist. |
| lun | Specifies the logical unit number of the data disk. This value is used to identify data disks within the VM and therefore must be unique for each data disk attached to a VM. |
| managed |
The managed disk parameters. |
| name | The disk name. |
| to |
Specifies whether the data disk is in process of detachment from the VirtualMachine/VirtualMachineScaleset |
| vhd | The virtual hard disk. |
| write |
Specifies whether writeAccelerator should be enabled or disabled on the disk. |
Property Details
caching
Specifies the caching requirements.
Possible values are:
None
ReadOnly
ReadWrite
Default: None for Standard storage. ReadOnly for Premium storage
caching?: "None" | "ReadOnly" | "ReadWrite"
Property Value
"None" | "ReadOnly" | "ReadWrite"
createOption
Specifies how the virtual machine should be created.
Possible values are:
Attach \u2013 This value is used when you are using a specialized disk to create the virtual machine.
FromImage \u2013 This value is used when you are using an image to create the virtual machine. If you are using a platform image, you also use the imageReference element described above. If you are using a marketplace image, you also use the plan element previously described.
createOption: "FromImage" | "Empty" | "Attach"
Property Value
"FromImage" | "Empty" | "Attach"
deleteOption
Specifies whether data disk should be deleted or detached upon VM deletion.
Possible values:
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
deleteOption?: "Delete" | "Detach"
Property Value
"Delete" | "Detach"
detachOption
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 mode and is not supported for VirtualMachineScaleSet. To force-detach a data disk update toBeDetached to 'true' along with setting detachOption: 'ForceDetach'.
detachOption?: "ForceDetach"
Property Value
"ForceDetach"
diskSizeGB
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.
diskSizeGB is the number of bytes x 1024^3 for the disk and the value cannot be larger than 1023
diskSizeGB?: number
Property Value
number
image
The source user image virtual hard disk. The virtual hard disk will be copied before being attached to the virtual machine. If SourceImage is provided, the destination virtual hard drive must not exist.
image?: VirtualHardDisk
Property Value
lun
Specifies the logical unit number of the data disk. This value is used to identify data disks within the VM and therefore must be unique for each data disk attached to a VM.
lun: number
Property Value
number
managedDisk
The managed disk parameters.
managedDisk?: ManagedDiskParameters
Property Value
name
The disk name.
name?: string
Property Value
string
toBeDetached
Specifies whether the data disk is in process of detachment from the VirtualMachine/VirtualMachineScaleset
toBeDetached?: boolean
Property Value
boolean
vhd
writeAcceleratorEnabled
Specifies whether writeAccelerator should be enabled or disabled on the disk.
writeAcceleratorEnabled?: boolean
Property Value
boolean
