vim.vm.device.VirtualDiskOption.FlatVer2BackingOption
=====================================================
This data object type contains the available options when backing a virtual disk using a host file with the flat file format used in VMware Server and in ESX Server 2.x and greater. Flat disks are pre-allocated, whereas sparse disks are grown as needed.
:extends: vim.vm.device.VirtualDeviceOption.FileBackingOption_
Attributes:
diskMode (`vim.option.ChoiceOption`_):
The disk mode. Valid disk modes are:
* `persistent`_
*
* `independent_persistent`_
*
* `independent_nonpersistent`_
*
* See
* `VirtualDiskMode`_
*
split (`vim.option.BoolOption`_):
Flag to indicate whether or not the host supports allowing the client to select whether or not a disk should be split.
writeThrough (`vim.option.BoolOption`_):
Flag to indicate whether or not the host supports allowing the client to select "writethrough" as a mode for virtual disks. Typically, this is available only for VMware Server Linux hosts.
growable (`bool`_):
Indicates whether or not this disk backing can be extended to larger sizes through a reconfigure operation.If set to true, reconfiguring this virtual disk with a `capacityInKB`_ value greater than its current value will grow the disk to the newly specified size.
hotGrowable (`bool`_):
Indicates whether or not this disk backing can be extended to larger sizes through a reconfigure operation while the virtual machine is powered on.If set to true, reconfiguring this virtual disk with a `capacityInKB`_ value greater than its current value will grow the disk to the newly specified size while the virtual machine is powered on.
uuid (`bool`_):
Flag to indicate whether this backing supports disk UUID property.
thinProvisioned (`vim.option.BoolOption`_):
Flag to indicate if this backing supports thin-provisioned disks.When creating a thin-provisioned disk (or converting an existing disk to to a thin-provisioned one), both the target datastore and the host accessing it must support thin-provisioning. This flag indicates only the host capability. See `perFileThinProvisioningSupported`_ for datastore capability.
eagerlyScrub (`vim.option.BoolOption`_):
Flag to indicate if this backing supports eager scrubbing.
deltaDiskFormat (`vim.option.ChoiceOption`_):
Delta disk formats supported. Valid values are:
* `redoLogFormat`_
*
* `nativeFormat`_
*
*
*
deltaDiskFormatsSupported ([`vim.vm.device.VirtualDiskOption.DeltaDiskFormatsSupported`_]):
Delta disk formats supported for each datastore type.
