System Configuration; Host Modes And Host Mode Options - Hitachi G1000 Hardware Manual

System configuration

After physical installation of the storage system is complete, users can
configure the storage system for open-systems operations with assistance
from a Hitachi Data Systems representative, if necessary.
Refer to the following documents for information and instructions about
configuring your storage system for open-systems operations:
• The host attachment guide provides information and instructions to
configure the storage system and data storage devices for attachment to
the open-systems hosts.
• The Hitachi Command Suite Installation and Configuration Guide or the
System Administrator Guide provides instructions for installing,
configuring, and using Device Manager - Storage Navigator to perform
resource and data management operations on the storage system.
• The Provisioning Guide for Open Systems describes and provides
instructions for configuring the storage system for host operations,
including FC port configuration, LUN mapping, host groups, host modes
and host mode options, and LUN security.
Each Fibre Channel port on the storage system 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 storage systems and provides instructions for configuring and
performing SNMP operations.
• The Provisioning Guide for Open Systems and Hitachi Volume Shredder
User Guide provide instructions for configuring multiple custom volumes
(logical units) under single LDEVs on the VSP G1000, G1500, and VSP
F1500 . 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

The VSP G1000, VSP G1500, and VSP F1500 support 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 Microsoft Windows hosts are connected to
separate Fibre Channel ports, or through a switch to a single Fibre Channel

Note: Queue depth and other parameters may need to be adjusted
for the storage system. See the host attachment guide for queue
depth and other requirements.
