9-1 Overview of Device Manager Host Operations
A computer system that uses storage on a subsystem is referred to as a host. The Device Manager agents
installed on these hosts periodically send information about the hosts and the storage used by the hosts to the
Device Manager server. This enables monitoring of how the hosts use the storage in the storage subsystems
managed by Device Manager.
In Device Manager, a world wide name (WWN) or a group of world wide names can be handled as a host. If
you have not installed the Device Manager agent on a host, you can set a Device Manager host on the basis of
the configuration of the physical host. Also, you can set a Device Manager host on the basis of a group of
WWNs that access a specific storage in a storage subsystem managed by Device Manager.
The external port used in External Storage XP of StorageWorks XP12000/XP10000 operates external volumes
that are managed by the external storage subsystem, in the same way as a host. Therefore, Device Manager
manages the external port as a host.
Device Manager host operations can be performed by the system administrator, storage administrator, local
system administrator, and local storage administrator. Guest and local guest users can only view the host
information.
