MSFT_StorageObject class

  • Article

MSFT_StorageObject is the base class for all storage object classes.

The following syntax is simplified from Managed Object Format (MOF) code.

Syntax

class MSFT_StorageObject
{
  String ObjectId;
  String UniqueId;
  String PassThroughIds;
  String PassThroughServer;
  String PassThroughNamespace;
  String PassThroughClass;
};

Members

The MSFT_StorageObject class has these types of members:

Properties

The MSFT_StorageObject class has these properties.

ObjectId

Data type: String

Access type: Read-only

Qualifiers: Key, Required

ObjectId is a mandatory property that is used to opaquely and uniquely identify an instance of a class. ObjectId values are required to be globally unique. That is, no two objects should ever have the same ObjectId, even if they are managed by separate storage management providers, or are on different storage subsystems.

The ObjectId is created and maintained for use of the Storage Management Providers and their clients to track instances of objects. If an object is visible through two different paths for example, if there are two separate storage management providers that point to the same storage subsystem then the same object may appear with two different ObjectId values. For determining if two object instances are the same object, refer to the UniqueId property.

PassThroughClass

Data type: String

Access type: Read-only

The WMI class name of the proprietary storage provider object.

PassThroughIds

Data type: String

Access type: Read-only

A comma-separated list of all implementation specific keys. This list is used by storage management applications to access the vendor proprietary object model. The list should be in the form: key1='value1', key2='value2'.

PassThroughNamespace

Data type: String

Access type: Read-only

The WMI namespace that contains the proprietary storage provider classes.

PassThroughServer

Data type: String

Access type: Read-only

The computer that is hosting the proprietary storage provider classes.

UniqueId

Data type: String

Access type: Read-only

Qualifiers: Required

UniqueId is a mandatory property that is used to uniquely identify a logical instance of a storage subsystem's object. This value must be the same for an object viewed by two or more provider instances, even if they are running on separate management servers. UniqueId can be any globally unique, opaque value, unless otherwise specified by a derived class.
