IBMTSSVC_StorageVolume

The IBMTSSVC_StorageVolume class represents a device that is presented by the cluster that can be mapped as a SCSI LUN to host systems on the SAN. A volume is formed by allocating a set of extents from a pool.

Properties

The IBMTSSVC_StorageVolume class extends the CIM_StorageVolume class and has the properties shown in Table 1.

Table 1. IBMTSSVC_StorageVolume properties
Property	Type	Qualifier	Description
Access	Uint16		Describes the media. Code Semantics 0 Unknown 1 Readable 2 Writeable 3 Read/Write Supported 4 Write Once
AccessGranted	Boolean	ModelCorrespondence (CIM_Controller. AuthorizationView)	A quick interface to find devices with no AuthorizationSubject association to an AccessControl Information instance, either directly or by use of a controller. If set to true, the device has granted access to a consumer. If set to false, no access has been granted.
Additional Availability	Uint16[]	Deprecated(CIM_Associated PowerManagementService. PowerState CIM_Managed SystemElement.Operational Status CIM_EnabledLogical Element.EnabledState), ModelCorrespondence (CIM_LogicalDevice. Availability)	Additional availability and status of the device, beyond that specified in the Availability property. The Availability property denotes the primary status and availability of the device. In some cases, it is not sufficient to denote the complete status of the device. In those cases, the AdditionalAvailability property can be used to provide further information.
