15.5.1 Device Manager

The Device Manager (DM) builds on the IBM Director technology. It uses the Service Level Protocol (SLP) to discover supported storage systems on the SAN. The SLP enables the discovery and selection of generic services accessible through an IP network. The DM then uses managed objects to manage these devices.

DM also provides a subset of configuration functions for the managed devices, primarily LUN allocation and assignment. Its functionality includes aggregation and grouping of devices and provides policy based actions across multiple storage devices. These services communicate with the CIM Agents that are associated with the particular devices to perform the required configuration. Devices that are not SMI-S compliant are not supported. The DM also interacts and provides SAN management functionality when the IBM Tivoli SAN Manager is installed.

The DM health monitoring keeps you aware of hardware status changes in the discovered storage devices. You can drill down to the status of the hardware device, if applicable. This enables you to understand which components of a device are malfunctioning and causing an error status for the device. Figure 15-3shows an example of a DM view.

In summary, the Device Manager is responsible for:

￿Discovery of supported devices (SMI-S compliant)

￿Data collection (asset, availability, configuration)

￿Providing a topographical view of storage
