Accessuint16
DescriptionstringAccess describes whether the allocated storage extent is 1 (readable), 2 (writeable), or 3 (both). NOTE: This property is a copy of the CIM_StorageExtent.Access property, except deprecated values. See the description of the CIM_StorageExtent.Access property for details.

HostExtentNamestring
DescriptionstringA unique identifier for the host extent. The identified host extent is used for the storage resource allocation. NOTE: This property is a copy of the CIM_StorageExtent.Name property. See the description of CIM_StorageExtent.Name property for details.

HostExtentNameFormatuint16
DescriptionstringThe HostExtentNameFormat property identifies the format that is used for the value of the HostExtentName property. NOTE: This property is a copy of the CIM_StorageExtent.NameFormat property, excluding deprecated values. See the description of CIM_StorageExtent.NameFormat class for details. 7 = Serial Number/Vendor/Model (SNVM) SNVM is 3 strings representing the vendor name, product name within the vendor namespace, and the serial number within the model namespace. Strings are delimited with a '+'. Spaces may be included and are significant. The serial number is the text representation of the serial number in hexadecimal upper case. This represents the vendor and model ID from SCSI Inquiry data; the vendor field MUST be 8 characters wide and the product field MUST be 16 characters wide. For example, 'ACME____+SUPER DISK______+124437458' (_ is a space character) 9 = NAA as a generic format. See http://standards.ieee.org/regauth/oui/tutorials/fibrecomp_id.html. Formatted as 16 or 32 unseparated uppercase hex characters (2 per binary byte). For example '21000020372D3C73' 10 = EUI as a generic format (EUI64) See http://standards.ieee.org/regauth/oui/tutorials/EUI64.html. Formatted as 16 unseparated uppercase hex characters (2 per binary byte) 11 = T10 vendor identifier format as returned by SCSI Inquiry VPD page 83, identifier type 1. See T10 SPC-3 specification. This is the 8-byte ASCII vendor ID from the T10 registry followed by a vendor specific ASCII identifier; spaces are permitted. For non SCSI volumes, 'SNVM' may be the most appropriate choice. 12 = OS Device Name (for LogicalDisks). See LogicalDisk Name description for details.

HostExtentNameNamespaceuint16
DescriptionstringIf the host extent is a SCSI volume, then the preferred source for SCSI volume names is SCSI VPD Page 83 responses. NOTE: This property is a copy of the CIM_StorageExtent.NameNamespace property. See the description of CIM_StorageExtent.NameNamespace class for details. Page 83 returns a list of identifiers for various device elements. The metadata for each identifier includes an Association field, identifiers with association of 0 apply to volumes. Page 83 supports several namespaces specified in the Type field in the identifier metadata. See SCSI SPC-3 specification. 2 = VPD Page 83, Type 3 NAA (NameFormat SHOULD be NAA) 3 = VPD Page 83, Type 2 EUI64 (NameFormat EUI) 4 = VPD Page 83, Type 1 T10 Vendor Identification (NameFormat T10) Less preferred volume namespaces from other interfaces: 5 = VPD page 80, Serial number (NameFormat SHOULD be Other) 6 = FC NodeWWN (NameFormat SHOULD be NAA or EUI) 7 = Serial Number/Vendor/Model (NameFormat SHOULD be SNVM) cThe preferred namespace for LogigicalDisk names is platform specific device namespace; see LogigicalDIsk Description. 8 = OS Device Namespace.

HostExtentStartingAddressuint64
DescriptionstringThe HostExtentStartingAddress property identifies the starting address on the host storage extent identified by the value of the HostExtentName property that is used for the allocation of the virtual storage extent. A value of NULL indicates that there is no direct mapping of the virtual storage extent onto the referenced host storage extent. NOTE: This property is a copy of the CIM_BasedOn.StartingAddess property. See the description of CIM_BasedOn association for details.

HostResourceBlockSizeuint64
DescriptionstringSize in bytes of the blocks that are allocated at the host as the result of this storage resource allocation or storage resource allocation request. If the block size is variable, then the maximum block size in bytes should be specified. If the block size is unknown or if a block concept does not apply, then the value 1 shall be used. NOTE: This property is a copy of the CIM_StorageExtent.BlockSize property. See the description of the CIM_StorageExtent.BlockSize property for details.

PUnitstringbyte
Limituint64
DescriptionstringThe maximum amount of blocks that will be granted for this storage resource allocation at the host. The blocksize is specified by the value of the HostResourceBlockSize property.Usually the value this property would reflect a maximum size for the allocated host extent that matches the size of the virtual storage extent presented to the consumer. A value less than that would indicate a situation where a sparsely populated virtual storage extent is expected, where the fill rate is limited by the value of the Limit property.

OverridestringVirtualQuantity
VirtualQuantityUnitsstringcount(fixed size block)
DescriptionstringThis property specifies the units used by the VirtualQuantity property. The value shall match "count(fixed size block)" | "byte". The default value "count(fixed size block)" assumes that the implementation knows a fixed block size and conveys the block size through the value of the VirtualResourceBlockSize property. However, if the VirtualResourceBlockSize property has a value "1", this indicates an unknown or variable block size; in this case the value of the VirtualQuantityUnit property should be set to "byte", such that the value of the VirtualQuantity property is measured directly in byte. NOTE: The IsPUnit qualifier already formally restricts the value of this property to be a unit as specified in DMTF DSP0004:2.5.0, Annex C; in addition, the normative text in the description of this property above further constrains the value to match "byte" | "count(fixed size block)".

VirtualResourceBlockSizeuint64
DescriptionstringSize in bytes of the blocks that are presented to the consumer as the result of this storage resource allocation or storage resource allocation request. If the block size is variable, then the maximum block size in bytes should be specified. If the block size is unknown or if a block concept does not apply, then the value 1 shall be used. NOTE: The use of 1 (and not 0) to indicate that the blocksize is unknown still allows the use of the VirtualQuantity property to convey the size in blocks of size 1). NOTE: This property is a copy of the CIM_StorageExtent.BlockSize property. See the description of the CIM_StorageExtent.BlockSize property for details.
