Learn About Host-Agent Managed Storage Subsystems

The storage subsystem is managed through an Ethernet connection on a host instead of using the Ethernet connections on each controller. The storage management station communicates with the storage subsystem through the host that has host-agent management software installed. The host-agent takes requests from the storage management station through the Ethernet connection to the host, and then sends them to the controllers in the storage subsystem through the I/O connections between the host and storage subsystem. The controllers also use the I/O connections to send event information back to the storage management station.

To manage a storage subsystem through a host, you must define the host name or IP address of the host that is connected to the storage subsystems. (See the Storage System Planning Guide for more information.) You can then use the Edit >> Add Device or Tools >> Automatic Discovery pull-down menu options in the Enterprise Management Window to include the host (and attached storage subsystems) in the management domain . The Enterprise Management software uses the host's name or IP address to communicate with and find each storage subsystem (and its controllers) connected to the host. The Device Tree View in the Enterprise Management Window displays the storage subsystem under each host that provides a network management connection to the storage subsystem.
