Hitachi Unified Storage VM Block Module Hardware User Guide
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 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
®
applet program that can be
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.
For further information about Storage Navigator, see the Hitachi Storage
Navigator User Guide.
