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.

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.
