VirtualDiskFlatVer2BackingOption

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.

ChoiceOption

diskMode

Required

The ChoiceOption data object type defines a set of supported string values, a localizable description for each value, and the default value.

BoolOption

split

Required

The BoolOption data object type describes if an option is supported ("true") and if the option is set to "true" or "false" by default.

BoolOption

writeThrough

Required

The BoolOption data object type describes if an option is supported ("true") and if the option is set to "true" or "false" by default.

boolean

growable

Required

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.

boolean

hotGrowable

Required

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.

boolean

uuid

Required

Flag to indicate whether this backing supports disk UUID property.

BoolOption

thinProvisioned

Required

The BoolOption data object type describes if an option is supported ("true") and if the option is set to "true" or "false" by default.

BoolOption

eagerlyScrub

Required

The BoolOption data object type describes if an option is supported ("true") and if the option is set to "true" or "false" by default.
