MSFT_SMPool class

Represents a storage pool. A storage pool is a logical grouping of physical disks that may be used to create virtual disks.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Windows Server 2012 R2 and Windows Server 2012: This class does not inherit from MSFT_SMStorageObject which is new for Windows Server 2016.

Identifier

Data type: String

Access type: Read-only

Qualifiers: Required

The ID of the logical instance of the object. This ID must be unique within the scope of the storage system.

This property is inherited from MSFT_SMStorageObject.

Windows Server 2012 R2 and Windows Server 2012: This property is present, but is not inherited from MSFT_SMStorageObject .

LowSpaceWarningThreshold

Data type: uint16

Access type: Read-only

Qualifiers: MinValue (0), MaxValue (100), ModelCorrespondence ("CIM_StoragePool.RemainingManagedSpace"), PUnit ("percent"), Units ("Percentage")

A low space warning is generated when the remaining space is reduced to this percentage of the total storage capacity.

Name

Data type: String

Access type: Read-only

A human-readable string used to identify the storage pool. This property is unique within the storage subsystem.
