Hitachi Global Link Manager Software Installation and Configuration Guide

Manager, Device Manager, Tuning Manager, and other Hitachi Command
Suite server products, and is always updated to the latest version.
Global Link Manager client
A machine on which the Global Link Manager GUI is used. The Global Link
Manager GUI provides a user interface for managing hosts by using Global
Link Manager.
Remote management client
A Hitachi Command Suite Common Agent Component instance or the
computer the instance is installed on that connects to and controls a host via
a LAN. A remote management client is required for and can only be used to
manage HDLM instances installed on hosts running VMware without an
underlying OS (hereafter referred to as the VMware-version of HDLM).
Host
A machine on which application programs are installed. In the system in
which Global Link Manager is used, each host uses storage systems as
external storage devices, and multipath management software manages the
paths between hosts and storage systems. When an ESXi hypervisor is
running on a server without an underlying OS (in other words, VMware is
used as the OS), the server is referred to as a host.
HDLM, DMP, or HP-UX multipathing manages the paths between hosts and
storage systems. The multipath management software improves the
reliability of the system by balancing the load on paths and switching paths
when a problem occurs.
For communication between the Global Link Manager server and hosts, one of
the following agents is required, depending on the multipath management
software:
• Device Manager agent (if using HDLM earlier than 5.8)
• Hitachi Command Suite Common Agent Component
• Global Link Manager agent (if using DMP, or HP-UX multipathing)
Hitachi Command Suite Common Agent Component refers to the component
included in version 5.8 or later of HDLM or the Global Link Manager agent.
Storage system
An external storage device connected to hosts. The storage systems whose
paths are managed by the multipath management software are subject to
Global Link Manager management. Note that when DMP or HP-UX
multipathing is used as multipath management software, For details about
the storage systems that can be managed by Global Link Manager, see the
Release Notes for Global Link Manager.
