Description

A StorageVolume is an Extent that is presented to the Operating System (for example, by a hardware RAID cabinet), to a File System (for example, by a software volume manager) or to another entity. StorageVolumes do not participate in StorageRedundancy Groups. They are directly Realized in hardware or are the end result of assembling lower level Extents.This is a cascaded class representing the Storage Volume on the Backend Storage and not on the SVC

Properties

IdTypeRangeDescription
Key
CreationClassName string
Max Length256
CreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.
DeviceID string
Max Length64
An address or other identifying information to uniquely name the LogicalDevice.
SystemCreationClassName string
Max Length256
The scoping System's CreationClassName.
SystemName string
Max Length256
The scoping System's Name.

Note - this property originally touched on two concepts that are now separated into this property and NameNamespace. Values 2,3,4,5,6, and 8 are retained for backwards compatibility but are deprecated in lieu of the corresponding values in CIM_StorageVolume.NameNamespace. Format of the Name property. Values are (per SCSI SPC-3):2 = VPD Page 83, NAA IEEE Registered Extended (VPD83NAA6)(DEPRECATED)3 = VPD Page 83, NAA IEEE Registered (VPD83NAA5)(DEPRECATED)4 = VPD Page 83, (VPD83Type2) (DEPRECATED)5 = VPD Page 83,T10 Vendor Identification (VPD83Type1) (DEPRECATED)6 = VPD Page 83, Vendor Specific (VPD83Type0) (DEPRECATED)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. Vendor and Model represent 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 +124437458'8 = Node WWN (for single LUN/controller) (NodeWWN)(DEPRECATED)9 = NAA as a generic format. Seehttp://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) Seehttp://standards.ieee.org/regauth/oui/tutorials/EUI64.htmlFormatted 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 2. See T1- SPC-3 specification. 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.

The preferred source for volume names is SCSI VPD Page 83 responses. 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 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)
OtherNameFormat string
A string describing the format of the Name property when NameFormat includes the value 1,"Other".
OtherNameNamespace string
A string describing the namespace of the Name property when NameNamespace includes the value 1,"Other".
