Chapter 1 Overview of Red Hat®Linux®Configuration

1.1 Red Hat®Linux®Configuration

This document describes the requirements and procedures for connecting the Lightning

9900™ V subsystem to a Red Hat®Linux®system and configuring the new Lightning 9900™ V

devices for operation with the Red Hat®Linux®operating system. The Hitachi Data Systems

Customer Service representative performs the physical installation of the 9900V subsystem.

The user prepares for 9900V subsystem installation and configures the new 9900V devices

with assistance as needed from the Hitachi Data Systems representative.

Configuration of the 9900V SCSI disk devices for Red Hat®Linux®includes:

 Setting the host mode and configuring the 9900V fibre-channel ports (see section 2.3).

 Connecting to the 9900V subsystem (see section 2.4).

 Configuring the host fibre-channel adapters (see section 2.5).

 Verifying device recognition (see section 2.6).

 Setting the number of LUs (see section 3.1).

 Partitioning the devices (see section 3.2).

 Creating the file systems (see section 3.3.1).

 Creating the mount directories (see section 3.3.2).

 Creating the mount table (see section 3.3.3).

 Certifying the file system (see section 3.3.4).

 Setting the auto mount procedures (see section 3.3.5).

For further information on Red Hat®Linux®please refer to the Red Hat®Linux®user

documentation, or contact technical support.

Note on the term “SCSI disk”: The 9900V logical devices are defined to the host as SCSI disk

devices, even though the interface is fibre-channel.

1.2 The Lightning 9900™ V Array Subsystem

The Hitachi Lightning 9900™ V RAID subsystem supports concurrent attachment to multiple

UNIX®-based and PC-server platforms. Please contact your Hitachi Data Systems account

team for the latest information on platform support. The 9900V subsystem provides

continuous data availability, high-speed response, scaleable connectivity, and expandable

capacity for PC server and open-system storage. The 9900V subsystem can operate with

multihost applications and host clusters, and is designed to handle very large databases as

well as data warehousing and data mining applications that store and retrieve terabytes of

data.

The Hitachi Lightning 9900™ V subsystem can be configured with fibre-channel, FICON™,

and/or ExSA™ (Extended Serial Adapter™) ports to provide connectivity with S/390®

mainframe hosts as well as open-system hosts. For further information on the 9900V

subsystem, please refer to the Hitachi Freedom Storage™ Lightning 9900™ V User and

Reference Guide (MK-92RD100), or contact your Hitachi Data Systems account team.

For further information on the 9900V subsystem, please refer to the Hitachi Lightning 9900™

V Series User and Reference Guide (MK-92RD100), or contact your Hitachi Data Systems

account team, or visit Hitachi Data Systems online (http://www.hds.com).

Note on the term “SCSI disk”: The 9900V logical devices are defined to the host as SCSI disk

devices, even though the interface is fibre-channel.
