Host Modes And Host Mode Options; Storage Navigator - Hitachi HUS VM Hardware User's Manual

including FC port configuration, LUN mapping, host groups, host modes
and host mode options, and LUN Security.
Each fibre-channel port on the HUS VM provides addressing capabilities
for up to 2,048 LUNs across as many as 255 host groups, each with its
own LUN 0, host mode, and host mode options. Multiple host groups are
supported using LUN Security.
• The Hitachi SNMP Agent User Guide describes the SNMP API interface for
the VSP storage systems and provides instructions for configuring and
performing SNMP operations.
• The Hitachi Unified Storage VM Block Module Provisioning Guide and
Hitachi Volume Shredder User Guide provide instructions for configuring
multiple custom volumes (logical units) under single LDEVs on the HUS
VM . The Provisioning Guide for Open Systems also provides instructions
for configuring size-expanded logical units by concatenating multiple
logical units to form individual large logical units.

Host Modes and host mode options

HUS VM supports connection of multiple server hosts of different platforms to
each of its ports. When your system is configured, the hosts connected to
each port are grouped by host group or by target. For example, if Solaris and
Windows hosts are connected to a fibre port, a host group is created for the
Solaris hosts, another host group is created for the Windows hosts, and the
appropriate host mode and host mode options are assigned to each host
group. The host modes and host mode options provide enhanced
compatibility with supported platforms and environments.
The host groups, host modes, and host mode options are configured using
the LUN Manager software on Storage Navigator. For further information on
host groups, host modes, and host mode options, refer to the Hitachi Unified
Storage VM Block Module Provisioning Guide.

Storage Navigator

Storage Navigator is the GUI that accesses the features in the firmware and
is used to set up and monitor the storage system. It can be installed on a PC,
laptop, or workstation. It communicates via a LAN to the SVP in the HUS VM
storage system. The SVP obtains storage system configuration and status
information and sends user-initiated commands to the storage system. The
Storage Navigator GUI displays detailed storage system information and
allows users to configure and perform storage operations on the system.
Storage Navigator is provided as a Java
executed on any machine that supports a Java Virtual Machine (JVM). A PC
hosting the Storage Navigator software is called a remote console. Each time
a remote console accesses and logs into the SVP of the desired storage
system, the Storage Navigator applet is downloaded from the SVP to the
remote console. The following figure illustrates remote console and SVP
configuration for Storage Navigator.
