A-2 CIM/WBEM Features of Device Manager
CIM/WBEM of Device Manager version 1.1 provides the three features specified in SMI-S:
• Objection operation feature
• Indication feature
• Service discovery feature
These features are described below:
Object operation feature:
The SMI-S specifications, which Device Manager conforms to, define the interfaces for devices
that make up a storage network, such as storage subsystems, virtual storage systems, switches,
and hosts. The features that need to be provided by the management service to manage the
devices are grouped in a profile for each device.
The profiles used by the CIM/WBEM features of Device Manager are the Array profile and its
subprofiles. The Array profile defines the interfaces for storage subsystems.
Indication feature
The indication feature is the event notification feature defined by CIM. When an event occurs in
a CIM server, the CIM server reports the indication instance, which shows the information about
the event (such as generation or deletion of a CIM instance), to CIM clients. For a CIM client to
receive indications, its location and transmission conditions for indications must be registered in
the CIM server beforehand. For details on how to register, see the SNIA website.
Device Manager reports the occurrence of the following events:
• Generation of a volume
• Deletion of a volume
• Allocation of a path
• Cancellation of a path
Service discovery feature
Device Manager provides the service discovery feature based on the Service Location Protocol
(SLP).
The SLP is undergoing standardization by IETF and provides a way to discover desired services
available in a network. For details on the SLP, see RFC2608.
