Introduction
The HP NetRAID-1Si and HP NetRAID-3Si adapters and the integrated
HP NetRAID controllers built into certain HP NetServers let you link multiple
hard disk drives together to write data across them as if they were one large drive
You configure your linked drives in a RAID (redundant array of independent
disks) subsystem.
Initial installation and configuration of HP NetRAID Series adapters is described
in the HP NetRAID Series Installation and Configuration Guide. Initial
configuration of the integrated HP NetRAID controller is described in the HP
NetServer Integrated NetRAID Controller Configuration Guide.
This HP NetRAID Series User Guide contains information on the HP NetRAID
utilities that let you manage and make changes to an existing RAID system. This
guide covers the following topics:
•Overview of HP NetRAID Utilities
•HP NetRAID Assistant (for Windows NT and Windows 2000)
•HP NetRAID Config (for Novell NetWare, IBM OS/2, and SCO
OpenServer and UnixWare)
•HP NetRAID Express Tools (use with all supported network operating
systems)
•Reconstructing and Rebuilding Drives
•Capacity Expansion
•Monitor Alert List
•Alarm Control and Audible Warnings

1 Overview of HP NetRAID Utilities
Three HP NetRAID utilities can configure and manage HP NetRAID Series
subsystems. Integrated HP NetRAID controllers and HP NetRAID Series adapters
(HP NetRAID-1Si and HP NetRAID-3Si) use the same utilities. However, all
utilities are not available to all network operating systems.
•HP NetRAID Assistant is used only with Microsoft Windows NT and
Windows 2000. (This utility is similar to the one that you ran from the
HP NetServer Navigator CD-ROM to initially configure your
HP NetRAID subsystem.)
•HP NetRAID Config is a text-based RAID configuration utility that runs
under Novell NetWare, IBM OS/2, SCO OpenServer, and SCO UnixWare.
•HP NetRAID Express Tools is a text-based RAID configuration utility
available to all operating systems. HP NetRAID Express Tools has some
advanced features not available in the other utilities.

NOTE Consult the Hewlett-Packard World Wide Web site
(http://www.hp.com/go/netserver) or your local HP dealer for
compatibility of your adapter with the most current versions of
the network operating systems listed in the preceding table.

HP NetRAID Assistant
HP NetRAID Assistant is an object-oriented GUI management utility. It runs
under Microsoft Windows NT and Windows 2000, and it allows you to
reconfigure and manage your HP NetRAID subsystem and to monitor its status.
For complete instructions on using this utility, see Chapter 2, "HP NetRAID
Assistant," in this guide.
NOTE Users of all operating systems run HP NetRAID Assistant from
the HP NetServer Navigator CD-ROM to configure their
systems during initial installation.

HP NetRAID Config
HP NetRAID Config is a character-based, non-GUI utility that runs under all
supported operating systems other than Microsoft Windows NT and
Windows 2000. HP NetRAID Config allows you to reconfigure and manage your
HP NetRAID subsystem and to monitor its status.
HP NetRAID Config performs most of the same functions as HP NetRAID
Assistant as well as some additional ones, but it runs under Novell NetWare,
IBM OS/2, SCO OpenServer, and SCO UnixWare.
The command you use to start the HP NetRAID Config utility depends on which
NOS you are using.
•For Novell Netware, type load megamgr
•For IBM OS/2, type megaconf
•For SCO OpenServer, type megamgr
•For SCO UnixWare, type megamgr
For instructions on using this utility, see Chapter 3, "HP NetRAID Config," in this
guide.

HP NetRAID Express Tools
HP NetRAID Express Tools is available to all network operating systems because
this utility is contained in the firmware. HP NetRAID Express Tools contains
some advanced management and diagnostic utilities that are not available with
HP NetRAID Assistant or HP NetRAID Config.
NOTE To access HP NetRAID Express Tools you must restart the
HP NetServer.
To start HP NetRAID Express Tools:
1. Log off all users, close all applications, and power down the HP NetServer.
2. Restart the HP NetServer.
3. When the following prompt appears, press <Ctrl> <M>.
Option: Experienced users may press <Ctrl> <M> for
HP NetRAID Express Tools now.

HP NetRAID Utility Comparison Chart
The three HP NetRAID utilities (HP NetRAID Assistant, HP NetRAID Config,
and HP NetRAID Express Tools) perform many of the same functions, but they
are not identical.
Parameters with default values and functions that are not shared by each of these

Chapter 1 Overview of HP NetRAID Utilities

NOTE Write-Back means that data is written to disk only when it is
forced out of the cache. Write-Back is efficient because an
entry may be written many times in the cache without a disk
access. While this setting increases performance, data can be
lost if power fails.
Write-Back is NOT recommended unless one of the following
is true:
•The HP NetRAID adapter is an HP NetRAID-3Si, which
has a Battery Backup Unit.
•Your system is equipped with a UPS (uninterruptible
power supply).
•Your system is an HP NetServer LH 3000/3000r,
LH 6000/6000r, or LT 6000r that is equipped with a
charged accessory Battery Backup Module.
Write-Back is not certified for any logical drive used as a
Novell NetWare volume.
