The IBM TotalStorage Multiple Device Manager is composed of three subcomponents:
򐂰 Device Manager
򐂰
TPC for Disk
򐂰 TPC for Replication
They are described in the following sections.
14.5.1 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
