7-2 CIM/WBEM features of Device Manager
CIM/WBEM of Device Manager provides the four features specified in SMI-S:
Object operation feature
Indication feature
Service discovery feature
Performance information acquisition 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 them, 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.
Just by specifying the type of service, SLP clients can obtain information (such as URLs) about
how to access the available services, and information about service attributes.
In Device Manager, the Device Manager server uses the SLP to report information about the
WBEM Service.
Performance information acquisition feature
Using the CIM interface, Device Manager acquires information about I/Os to ports and LDEVs
as performance information of the storage subsystem.
