Data Object Description
This data object type contains information about a disk in a virtual machine.The virtual disk backing object types describe the different virtual disk backings available. The disk format version in each case describes the version of the format that is used.
Supported virtual disk backings:
- Sparse disk format, version 1 and 2
- The virtual disk backing grows when needed. Supported only for VMware Server.
- Flat disk format, version 1 and 2
- The virtual disk backing is preallocated. Version 1 is supported only for VMware Server.
- Space efficient sparse disk format
- The virtual disk backing grows on demand and incorporates additional space optimizations.
- Raw disk format, version 2
- The virtual disk backing uses a full physical disk drive to back the virtual disk. Supported only for VMware Server.
- Partitioned raw disk format, version 2
- The virtual disk backing uses one or more partitions on a physical disk drive to back a virtual disk. Supported only for VMware Server.
- Raw disk mapping, version 1
- The virtual disk backing uses a raw device mapping to back the virtual disk. Supported for ESX Server 2.5 and 3.x.
Properties
| Name | Type | Description |
|---|---|---|
| capacityInBytes* | xsd:long |
Capacity of this virtual disk in bytes.
Server will always populate this property. Clients must initialize it when
creating a new non -RDM disk or in case they want to change the current
capacity of an existing virtual disk, but can omit it otherwise.
If the disk is on a Virtual Volume datastore the disk size must be a multiple
of a megabyte.
Since vSphere API Release 5.5 |
| capacityInKB | xsd:long |
Deprecated.
As of vSphere API 5.5, use capacityInBytes.
Capacity of this virtual disk in kilobytes.
Information might be lost when actual disk size is rounded off to kilobytes.
If the disk is on a Virtual Volume datastore the disk size must be a multiple
of a megabyte.
|
| diskObjectId* | xsd:string |
Deprecated.
As of vSphere API 6.5, use vDiskId.
Virtual disk durable and unmutable identifier.
Virtual disk has a UUID field but that can be set through
VirtualDiskManager APIs.
This identifier is a universally unique identifier which is not settable.
VirtualDisk can remain in existence even if it is not associated with VM.
Since vSphere API Release 5.5 |
| guestReadOnly* | xsd:boolean |
Flag to indicate whether a disk should be presented to the guest
in read-only mode (limited by choice of adapter).
Since vSphere API Release 8.0.2.0 |
| independentFilters* | VirtualMachineBaseIndependentFilterSpec[] |
The IDs of the independent filters associated with the virtual disk.
This information is provided when retrieving configuration information for
an existing virtual machine. The client cannot modify this information on
a virtual machine.
Since vSphere API Release 7.0.2.1 |
| iofilter* | xsd:string[] |
IDs of the IO Filters associated with the virtual disk.
See id. This information
is provided when retrieving configuration information for
an existing virtual machine. The client cannot modify this information
on a virtual machine.
Since vSphere API Release 6.0 |
| nativeUnmanagedLinkedClone* | xsd:boolean |
Indicates whether a disk with
VirtualDiskFlatVer2BackingInfo backing is a linked
clone from an unmanaged delta disk and hence the
parent chain to
this delta disk will not be available.
Since vSphere API Release 6.7 |
| shares* | SharesInfo |
Deprecated.
As of vSphere API 4.1, use
shares.
Disk shares, used for resource scheduling.
|
| storageIOAllocation* | StorageIOAllocationInfo |
Deprecated.
As of vSphere API 6.5, use
Resource allocation for storage I/O.
Since vSphere API Release 4.1 |
| vDiskId* | ID |
ID of the virtual disk object as the first class entity.
See ID
The ID is a universally unique identifier for the disk lifecycle,
even if the virtual disk is not associated with VM.
Since vSphere API Release 6.5 |
| vDiskVersion* | xsd:int |
Disk descriptor version of the virtual disk.
Since vSphere API Release 8.0.1.0 |
| vFlashCacheConfigInfo* | VirtualDiskVFlashCacheConfigInfo |
Deprecated.
since vSphere 7.0 because vFlash Read Cache
end of availability.
vFlash cache configuration supported on this virtual disk.
