Properties

Name	Type	Description
blockSizeMb	xsd:int	Block size of VMFS. Determines maximum file size. The maximum number of blocks is typically fixed with each specific version of VMFS. To increase the maximum size of a VMFS file, increase the block size. The minimum block size is 1MB.
extent	HostScsiDiskPartition[]	The list of partition names that comprise this disk's VMFS extents. This property can be accessed via various enclosing objects. In VirtualCenter, where it can be accessed from multiple hosts, the value of this property may differ according to the context in which it is accessed. When accessed from the VmfsDatastoreInfo object, in VirtualCenter, this property reflects the extent information of any one of the hosts visible to the datastore. For a VirtualCenter system which manages ESX Server 2.x and ESX Server 3.x hosts, this extent information is only correlatable across hosts if the extents are exposed on the same adapter on all hosts which can access them. To find the extent names for a specific host, this same property should be accessed via the host's HostFileSystemVolume object, by correlating the uuid of the VMFS datastore in the VmfsDatastoreInfo object to the uuid in the FileSystemVolume object. For a Virtual Center system which manages only ESX Server hosts with versions 4.0 onwards , this extent information is correlatable across hosts, irrespective of the adapters the extents are exposed on.
forceMountedInfo*	HostForceMountedInfo	Information about 'forceMounted' VmfsVolume. When the system detects a copy of a VmfsVolume, it will not be auto-mounted on the host and it will be detected as 'UnresolvedVmfsVolume'. If user decides to 'forceMount' the VmfsVolume on the host, forceMountedInfo will be populated. It will not be set for automounted VMFS volumes. *Since* vSphere API 4.0
majorVersion	xsd:int	Major version number of VMFS.
maxBlocks	xsd:int	Maximum number of blocks. Determines maximum file size along with blockSize. See information about the blockSize.
ssd*	xsd:boolean	Indicates whether the volume is SSD backed. If unset, the information whether the volume is SSD backed is unknown. *Since* vSphere API 5.0
uuid	xsd:string	The universally unique identifier assigned to VMFS.
version	xsd:string	Version string. Contains major and minor version numbers.
vmfsUpgradable	xsd:boolean	Can the filesystem be upgraded to a newer version. See UpgradeVmfs

Description

blockSizeMb

xsd:int

Block size of VMFS. Determines maximum file size. The maximum number of blocks is typically fixed with each specific version of VMFS. To increase the maximum size of a VMFS file, increase the block size.

The minimum block size is 1MB.

extent

HostScsiDiskPartition[]

The list of partition names that comprise this disk's VMFS extents.

This property can be accessed via various enclosing objects. In VirtualCenter, where it can be accessed from multiple hosts, the value of this property may differ according to the context in which it is accessed. When accessed from the VmfsDatastoreInfo object, in VirtualCenter, this property reflects the extent information of any one of the hosts visible to the datastore.

For a VirtualCenter system which manages ESX Server 2.x and ESX Server 3.x hosts, this extent information is only correlatable across hosts if the extents are exposed on the same adapter on all hosts which can access them. To find the extent names for a specific host, this same property should be accessed via the host's HostFileSystemVolume object, by correlating the uuid of the VMFS datastore in the VmfsDatastoreInfo object to the uuid in the FileSystemVolume object.

For a Virtual Center system which manages only ESX Server hosts with versions 4.0 onwards , this extent information is correlatable across hosts, irrespective of the adapters the extents are exposed on.

forceMountedInfo*

HostForceMountedInfo

Information about 'forceMounted' VmfsVolume. When the system detects a copy of a VmfsVolume, it will not be auto-mounted on the host and it will be detected as 'UnresolvedVmfsVolume'. If user decides to 'forceMount' the VmfsVolume on the host, forceMountedInfo will be populated. It will not be set for automounted VMFS volumes.

Since vSphere API 4.0

majorVersion

xsd:int

Major version number of VMFS.

maxBlocks

xsd:int

Maximum number of blocks. Determines maximum file size along with blockSize. See information about the blockSize.

ssd*

xsd:boolean

Indicates whether the volume is SSD backed. If unset, the information whether the volume is SSD backed is unknown.

Since vSphere API 5.0

uuid

xsd:string

The universally unique identifier assigned to VMFS.

version

xsd:string

Version string. Contains major and minor version numbers.

vmfsUpgradable

xsd:boolean

Can the filesystem be upgraded to a newer version.
