Roadmap for setting up and configuring the NAS 200

The following roadmap presents the requirements and instructions required to set
up and configure the NAS 200. Following these directions and referring to the
appropriate sections of this book will help you in this task.

Configuration and administration tools (“Chapter 2. Configuration and
administration tools” on page 5)

The NAS 200 has several different methods of configuration depending on
your environment.

Determine how you will manage the device. You can manage the NAS 200
in “headless” mode or with a keyboard, display, and mouse directly attached
to each node. For “headless” management of the NAS 200, you can use
one of the following tools:
v Terminal Services, for remote configuration and management from

another device on the network

v Universal Manageability Services (UMS) for management through a web

browser

2 NAS 200 User’s Reference

v Windows 2000 for NAS, a Web-based GUI for those not familiar with the

Windows desktop

v IBM Advanced Appliance Configuration Utility (IAACU) for setup and

configuring multiple devices or other appliances on a single network

Having determined how you will manage the NAS 200, you can begin setup
and configuration of the device.

Step 1 - Initial network setup (“Chapter 3. Getting started” on page 19)

Configure the NAS 200 to enable access over the network.
First, use DHCP or static addressing to set up one network connection. If

you are running with a keyboard, display, and mouse, set up a network
connection to access the device. If you are running in a headless
environment, you can use one of the following methods:
v If DHCP is installed and the IP address requested can be determined,

you can use this method for initial setup, but you should change this
address to static later in the configuration.

v If you have multiple appliances or cannot determine the DHCP address,

you can install the IAACU utility to identify appliances and define IP
addresses. The tool will also allow you to set static addresses.

Next, complete the steps in “Initial setup and configuration” on page 20.

Step 2 - Define storage (“Chapter 4. Storage configuration” on page 23)

The NAS 200 comes with preconfigured storage spanning the internal hard
disk drives:

v A RAID-level 1E array, for the System partition (drive letter will be C:)
v A RAID-level 1E array, for the Maintenance partition (drive letter will be

D:)

v A RAID-level 5 array, comprised of the remaining storage. This array

consists of a single logical unit number (LUN), for the Data drive (drive
letter will be E). The size of this (LUN) depends on the number and size
of hard disk drives that came with your NAS 200.

You can use the preconfigured Data drive, or delete it and configure new
storage.

Step 3 - Completing setup (“Chapter 5. Completing setup” on page 27)

At this point you can define users and file shares to the NAS 200, to allow
the storage to be accessed by clients and servers on the network.

Step 4 - Additional functions (“Chapter 6. Additional administrative functions”

on page 35)

Additional functions are available for such tasks as backup and creating
persistent images. It is recommended that once you complete the setup and
configuration procedures, you use the Persistent Storage Manager Disaster
Recovery option (“Disaster Recovery” on page 39) or other method to back
up the system configuration in the event of a failure.

Chapter 1. Introduction 3

4 NAS 200 User’s Reference

Chapter 2. Configuration and administration tools

Attention

Changing the preloaded software configuration of this product, including

applying or installing unauthorized service packs or updates to preinstalled

software, or installing additional software products that are not included in

either the preloaded image or on the Supplementary CD, may not be

supported and could cause unpredictable results. For updated compatibility

information, please see

http://www.ibm.com/storage/nas

To correct problems with a preloaded software component, back up your user

and system data. Then use the Recovery CD to restore the preloaded

software image.

The NAS 200 appliance comes with the following configuration programs that you
can use to configure and administer the appliance:

v Terminal Services Client (page 6 and page 8)
v IBM Advanced Appliance Configuration Utility (IAACU, page 7 and page 9)
v Universal Manageability Services (page 7 and page 15)
v Windows 2000 for Network Attached Storage (page 7 and page 17)

This chapter describes these tools in general and then in detail.
In addition to these primary tools, the NAS 200 offers several secondary

administrative tools:

v Telnet Server support (page 18)
v Simple Network Management Protocol (SNMP) support (page 18)

There are several ways to setup and administer the NAS 200. Table 1 on page 6
suggests which tool you can use for specific functions, but does not list all options
or combinations. The administrator training-level or administrator preferences may
determine an alternate approach from that suggested in the table.

Using a keyboard, monitor, and mouse for setup and configuration

It is highly recommended that you directly attach a keyboard, monitor, and mouse to
the NAS 200 when:

v Initially setting up and configuring the device
v Changing or adding to RAID arrays (for example, adding a new array with

ServeRAID Manager, adding a new RAID controller, or adding a storage

expansion unit)
v Troubleshooting the device

Quad-Port Ethernet Adapter using SLICuser

Disaster Recovery Restores a previously saved PSM image of the system partition to a failed

machine. This will restore all configuration information on the machine. You
create the recovery boot diskette from the PSM tools in the Windows 2000
for NAS GUI.

Recovery CD Set Reinstalls the software to the original state as shipped on the machine;

however, does not restore configuration information (so configuration changes
you applied to the original shipped configuration are lost). You must first boot
with the Recovery Enablement Diskette, and then reboot with the Recovery
CD. To create the Recovery Enablement Diskette, run
\DiskImages\Recovdsk.bat on the Supplementary CD.

Terminal Services Client

6 NAS 200 User’s Reference

The Terminal Services Client, when installed on a workstation that is
attached to the same network as the NAS 200, enables you to remotely

administer the appliance using the NAS 200 desktop. If you are familiar with
administrative tasks using a Windows desktop, you can use Terminal
Services.

See “Terminal Services and the IBM NAS Administration Console” on
page 8 for more information.

IBM Advanced Appliance Configuration Utility (IAACU)

The IBM Advanced Appliance Configuration Utility (IAACU) aids in setting
up and reconfiguring the network configuration on your appliances. The
IAACU agent works with the IAACU Console to automatically detect the
presence of appliances on the network.

Once the appliance is detected by the IAACU Console, you can use the
IAACU to:

v Set up and manage the appliance’s network configuration, including

assigning the IP address, default gateway, network mask, and DNS
server to be used by the appliance.

v Start Universal Manageability Services on the appliance, enabling you to

do more advanced systems-management tasks

See “IBM Advanced Appliance Configuration Utility” on page 9 for more
information.

Universal Manageability Services

Universal Manageability Services (UM Services) provides point-to-point
remote management of client systems through a Web browser window. You
can use UM Services to:

v Learn detailed inventory information about your computers, including

operating system, memory, network cards and hardware

v Track your computers with features such as power management, event

log, and system monitor capabilities

v Upwardly integrate with Tivoli Enterprise, Tivoli NetView

Associates Unicenter, Microsoft SMS, and Intel
Suite

In addition, you can link to Windows 2000 for Network Attached Storage
and Terminal Services from UM Services.

See “Universal Manageability Services” on page 15 for more information.

Windows 2000 for Network Attached Storage

For administrators who are not familiar with the Windows operating
systems, the NAS 200 provides a Web-based GUI, Microsoft Windows 2000
for Network Attached Storage (Windows 2000 for NAS). Using Windows
2000 for NAS, you navigate through various administrative task categories
by clicking on the appropriate links or buttons, and then selecting a task
from that category.

Chapter 2. Configuration and administration tools 7

Terminal Services and the IBM NAS Administration Console

If you are familiar with Windows operating systems, you can use Terminal Services.
In some cases, you must use Terminal Services to complete administrative tasks.

You can access Terminal Services in two ways:

1. Through the UM Services browser, as described in step 3 on page 16.

2. By using the Terminal Services Client software.
To use Terminal Services Client, complete the following steps to install it on the

remote workstation and connect to your NAS 200 appliance:

1. Insert the Supplementary CD into the workstation CD-ROM drive.

2. Click Start → Run.

3. In the Open field, type (with quotes)

"x:\Terminal Services Client\Disk 1\setup.exe"

where x is the drive letter assigned to the CD-ROM drive. Then click OK to
begin the Terminal Services Client Setup program.

4. Accept the defaults in each window that opens or refer to the Microsoft
Windows documentation for more instructions. When the Terminal Services
Client Setup program is completed, proceed to the next step.

5. Check the workstation network TCP/IP protocol configuration settings.

Connecting to the desktop through Terminal Services

To connect to Terminal Services from your workstation, do the following:

1. Click Start → Programs → Terminal Services → Terminal Services Client.

2. In the Server field, select the computer name of the desired NAS 200 . If the
desired NAS 200 is not listed, enter the IP address or the computer name of the
NAS 200. The computer name is predefined as IBM5194-xxxxxxx, where
xxxxxxx is the serial number located in the lower right corner of the bezel on the
front of the appliance. If you have changed the computer name from the
predefined value, use that name instead.

For Size, select a size other than full screen in which the NAS 200 desktop will
appear, then click Connect to start the Terminal Services Client session. A user
log in window displays.

Log in. Type Administrator in the Username field, type password in the
password field, and then click OK to log in. Once you have logged in, you can
begin using Terminal Services Client to configure and manage your NAS 200.

Once you have logged into Terminal Services, you can perform administrative tasks
on the NAS 200, as if your keyboard, mouse, and monitor were directly attached to
it. The NAS 200 desktop contains a shortcut, titled IBM NAS Admin, to a special
console, the IBM NAS Administration console.

8 NAS 200 User’s Reference

IBM NAS Administration console

The IBM NAS Administration console contains all of the standard functions that are
contained in the standard Computer Management console available on any
Windows 2000 desktop, plus the following functions specific to the NAS 200, as
described in “Chapter 6. Additional administrative functions” on page 35:

v NAS Backup Assistant
v Persistent Storage Manager
v ServeRAID Configuration

Determining who is using the network-attached storage

Occasionally, the administrator may want to know who is using the
network-attached storage. The administrator can determine this information as
follows:

1. Start a Windows Terminal Services session from the administrator’s console to
the NAS 200.

2. Click on the IBM NAS Admin icon on the desktop.

3. In the left plane, click on File Systems, then Shared Folders, then Sessions.

4. The users currently using the storage are displayed. If necessary, you can close
those sessions with a right-click. Before you close a session, you can notify the
user that you are going to close the session by clicking on Start, Programs,

Accessories, Command Prompt, and then issuing the net send hostname
messagetext command.

IBM Advanced Appliance Configuration Utility

The IBM Advanced Appliance Configuration Utility (IAACU) helps you to set up and
reconfigure the network configuration on your NAS 200, as well as other IBM
appliances.

The IAACU agent, preinstalled on your NAS 200, works with the IAACU Console, a

™

-based application that is installed on a remote workstation. You can use the

Java
agent and console as a systems-management device to automatically detect the
presence of NAS 200 appliances on the network. Once the NAS 200 appliance is
detected by the IAACU Console, use the IAACU to set up and manage the
appliance’s network configuration, including assigning the IP address, default
gateway, network mask, and DNS server to be used by the appliance. You can also
use the IAACU to start Universal Manageability Services (UM Services) on the
appliance, enabling you to perform more advanced systems-management tasks.

For networks that are not currently running DHCP servers, the IAACU is useful for
automatically configuring network settings for newly added appliances, such as the
NAS 200.

However, networks with DHCP servers will also benefit from using the IAACU
because it enables you to reserve and assign the appliance IP address in an
orderly, automated fashion. Even when you use DHCP and do not reserve an IP
address for the appliance, you can still use the IAACU to discover appliances and
to start UM Services Web-based systems-management.

Notes:

1. The Advanced Appliance Configuration configures and reports the TCP/IP
settings of the first adapter on each appliance only. The first adapter is typically

the built-in Ethernet controller. Be sure to connect the built-in Ethernet connector
to the same physical network as your systems management console.

2. The Advanced Appliance Configuration Utility must be running to configure
newly installed appliances automatically.

3. The system running the Advanced Appliance Configuration Utility console
automatically maintains a copy of its database (ServerConfiguration.dat) in the
Advanced Appliance Configuration Station installation directory. To remove
previous configuration data, close the Advanced Appliance Configuration Utility,
delete this file, and then restart the utility. This deletes all previously configured
Families. However, the Advanced Appliance Configuration Utility will
automatically discover connected appliances and their network settings.

Once you connect the NAS 200 to your network, the IAACU agent automatically
reports the appliance’s serial number and type, the MAC address of its onboard
Ethernet controller, and whether DHCP is in use by the appliance. Furthermore, it
will report the hostname, primary IP address, subnet mask, primary DNS server
address, and primary gateway address if these are configured on the system.

The IAACU agent is preinstalled on your NAS 200 appliance.
Note: The IAACU agent periodically broadcasts the appliance IP settings. To

prevent the service from broadcasting this data periodically, stop the
iaaconfig service.

IAACU Console

The IAACU Console is a Java application that you install on one remote workstation
in your network for use as a systems-management console. For information on how
to install the IAACU Console, see Table 13 on page 79.

Note: The IAACU creates a private database that is specific to the IP subnetwork

to which it is attached. Therefore, do not install it on more than one
systems-management console residing on the same IP subnetwork.

The IAACU Console enables you to:
v Automatically discover NAS 200 appliances, as well as other IBM appliances,

that run the IAACU agent and are attached to the same physical subnet as the
IAACU Console.

When you start the IAACU Console, it automatically detects all appliances on
your physical subnet that are running the IAACU agent.

v Use a GUI-based application to configure the appliance network settings.

Use the IAACU to assign network parameters such as IP addresses, DNS and
gateway server addresses, subnet masks, and hostnames.

v Group discovered appliances into function-specific Families. Appliances are

added to a Family based on the appliance type. Appliances that perform the
same function appear in the same Family. (Note that all NAS 200 appliances are
in the same family.)

v Start UM Services Web-based systems-management console.

Launch UM Services on your appliances and perform advanced
systems-management tasks on a selected appliance with a single mouse click.

The IAACU Console is divided into two panes:

10 NAS 200 User’s Reference

v The Tree View Pane

The Tree View Pane, located on the left side of the IAACU Console window,
presents a list of all discovered NAS 200 appliances and includes any Families
you have previously defined. The Tree View Pane also includes groups for
appliances that do not fit any of the defined Families, that were not configured
using the IAACU, or that have IP addresses that conflict with other devices on
your network. When you click on any item in the Tree View, information about
that item (and any items that are nested below that item in the tree view)
displays in the Information Pane.

v The Information Pane

The Information Pane, located at the right side of the IAACU Console, displays
information about the item that is currently selected in the Tree View Pane. The
information that displays in the Information Pane varies depending on the item
that is selected. For example, if you select the All Appliances item from the Tree
View Pane, the Information Pane displays configuration information (IP settings,
hostname, serial number, and so on) about each of the NAS 200 appliances that
have been discovered by the IAACU Console. However, if you select a Family,
the Information Pane displays information about the Family settings for the
selected Family.

The IAACU Console also features the following menus:
v File: Use the File menu to import or export the IAACU Console configuration

data, to scan the network, or to exit the program.

v Family: Use the Family menu to add or delete Families, or to move Families up

or down in the tree view.

v Appliance: Use the Appliance menu to remove a previously discovered

appliance from a Family or group, and to add an appliance to the first matching
Family in the tree view.

v Help: Use the Help menu to display product information.

Discovering NAS 200 Appliances

Any NAS 200 appliance, or other IBM appliance, that is running and is connected to
the same subnet as the system running the IAACU Console is automatically
discovered when you start the IAACU Console. Discovered appliances appear in
the IAACU Console tree view (in the left pane of the IAACU Console window). Each
appliance will appear in two locations in the tree view:

1. Every discovered appliance is listed in the tree view under All Appliances.

2. Each discovered appliance will also appear in one of the following portions of
the tree view:

v In a Family

If the discovered appliance fits the requirements of a Family, it will
automatically appear as part of a Family.

Note: If a discovered appliance fits the requirements of more than one

Family, it is automatically added to the first appropriate Family that is
listed in the tree view, starting from the top of the tree. For information
on how to move appliances between families, see “Using Families and
Groups in the Tree View” on page 12.

v In the Orphaned Appliances group

If the discovered appliance does not fit a previously configured Family, it is
placed in the Orphaned Appliances group.

v In the Orphaned Externally Configured Appliances group

Chapter 2. Configuration and administration tools 11

Appliances that are running the IAACU agent, but that have a network
configuration that was not set by the IAACU agent or console, will appear in
the Orphaned Externally Configured Appliances group. If an appliance is
contained in the Orphaned Externally Configured Appliances group, you can
use the Adopt By First Matching Family function to add it to a previously
defined Family. For more information, see “Using the Adopt by First Matching
Family Function” on page 14.

Using Families and Groups in the Tree View

Families are important elements of the IAACU. They specify the parameters that the
IAACU uses to automatically categorize discovered appliances and to configure
them with the appropriate network settings. Family rules are defined solely by
appliance type or purpose. Each Family can contain only one type of appliance.
The only way to automatically apply predetermined network settings to newly
installed and discovered appliances is to create and use Families.

Appliances that match the rules criteria for a Family group can be automatically
configured to use predefined network settings. A Family can be configured to allow
appliances to use DHCP to configure their IP settings, or can be defined to
automatically assign IP settings (such as primary gateway and DNS server
addresses, assigning an IP address from a specified IP address range, and
specifying a subnet mask). Host names for discovered appliances can also be
defined so that they are allocated using either a prefix or appliance serial number.

The IAACU is not the only way to configure network settings. For example, network
settings can be configured using Terminal Services for Windows or by attaching a
keyboard and mouse to the appliance and using Windows Control Panel. If the
appliance network settings have been configured by a method other than using the
IAACU, the appliance will be discovered by the IAACU and it will be added to an
appropriate Family, if one exists. Appliances that have been configured using a
method other than the IAACU for which no appropriate family exists will appear in
the Orphaned Externally Configured Appliances group.

The Tree View Pane contains the following items:

v All Appliances

Every discovered appliance is listed in the tree view under All Appliances.

v Families

The Families group in the Tree View Pane shows all Families that have been
defined, with appliances that have already been assigned to each Family nested
beneath the Family name in the tree view. Families are defined by appliance
purpose, so all appliances that appear in a given family are of the same type. If
you select a Family from the Tree View Pane, a description of the Family and the
rules that are used to define the selected Family display in the Information Pane.
If you select an appliance from a Family in the Tree View Pane, the selected
appliance network settings display in the Information Pane.

If you are not using DHCP, the IAACU automatically assigns one IP address per
appliance, using available addresses within the range defined in the Family rules.
When a Family’s IP address range has been exhausted, the IAACU automatically
searches for other Families that have rules matching the appliance being
configured. If a matching Family with an available address is found, the appliance
will automatically be assigned to the Family that has available IP addresses. This
enables you to define multiple Families, each of which uses a set of
non-contiguous IP address ranges.

When an appliance is discovered on the network, the IAACU automatically
searches all previously defined Families, starting with the first Family listed in the

12 NAS 200 User’s Reference

Families tree view and moving downward. Appliances are automatically added to
the first defined Family that matches the appliance purpose. Therefore, the order
in which Families appear is important. To adjust this search order, right-click on a
Family and then select Move Up or Move Down to adjust its position within the
Families list.

v Orphaned Appliances

Any discovered appliances that have been configured using the IAACU but that
do not meet the rules for any existing Family are automatically added to the
Orphaned Appliances group.

v Orphaned Externally Configured Appliances

Any discovered appliance that has been configured without using the IAACU tool
and that does not meet the rules for any existing Family is automatically added to
the Orphaned Externally Configured Appliances group. Appliances configured
without the IAACU that meet the rules for any existing Family are automatically
added to the matching Family. To add an Orphaned Externally configured
Appliance to an appropriate Family that was created after the orphaned
appliance was discovered, right-click on the orphaned appliance and select
Adopt by First Matching Family. For more information, see “Using the Adopt by
First Matching Family Function” on page 14.

Note: The IAACU will not change manually configured network settings of

discovered appliances. If the manually configured IP and Subnet
addresses fit an existing Family, the IAACU will place that appliance into
that Family, but will not change any other settings (such as Host Name,
DNS, or gateway addresses).

v Conflicting Network Addresses

Any discovered appliance that has the same IP address as a previously
discovered appliance will be listed in the Conflicting Network Addresses group.

Creating a Family: To create a Family:

1. Select Create Family from the Family menu.
The IAACU Family Setup window displays.

2. Select the Appliance Family Rules.
The Appliance Family Rules determine what purpose an appliance must serve

to be included in the Family. You can select one of the following values:

v IBM TotalStorage NAS Appliances
v IBM xSeries 130 and 135

You should select IBM TotalStorage NAS Appliances for a family that is to
include your NAS 200.

3. Specify a Family name.
In the Family Name field type the name that will be used for this Family.

4. Specify network resources to be used by members of the Family.
You can use the IAACU to assign network resources for members of this

Family, or you can use a DHCP server to assign network resources.
v To use the IAACU to assign network resources, uncheck the Use DHCP

checkbox and fill in the following fields:

Min IP Address

The lowest IP address in a range of IP addresses that can be
assigned to an appliance that is a member of this Family

Chapter 2. Configuration and administration tools 13

Max IP Address

The highest IP address in a range of IP addresses that can be
assigned to an appliance that is a member of this Family

Subnet Mask

The subnet mask value that will be used by appliances that are
members of this Family

Default Gateway

The IP address of the default gateway that will be used by appliances
that are members of this Family (optional)

DNS The IP address of the DNS server that will be used by appliances

that are members of this Family (optional)

v To use a DHCP server to assign network resources, check the Use DHCP

checkbox. This will allow a DHCP server on your network to assign an IP
address and subnet mask and to specify the default gateway address and
address of the DNS server that will be used by appliances that are members
of this Family.

5. Select a Host Name Allocation Type.
The Host Name Allocation Type enables you to automatically specify a Host

Name that members of this Family will use. You can select one of the following
Host Name Allocation Types:

No Allocation

No preconfigured host name format will be assigned to appliances that
are members of this family.

Use Serial Number

The Serial Number of the discovered appliance will be used as a host
name for the appliance.

Use Prefix Name

A user-specified prefix, along with an incremental number for each
appliance, will be used for the host name of each appliance that is a
member of this Family. Type the desired prefix in the Host Name Prefix
field.

6. Click OK to save this Family.

Removing Appliances from Families: Use the Remove Appliance function to
delete an appliance from the IAACU Console database and view pane. Removing
an appliance that is no longer in use allows the IP address that was assigned to the
appliance to be allocated to another appliance. You can also remove an appliance
from a family and then rescan the network to add it to an appropriate Family that
appears higher in the Tree View pane.

To remove an appliance, right-click on the appliance, and then select Remove
Appliance from the pop-up menu.

v If the IAACU is unable to communicate with the selected appliance (because, for

example, it has been removed from the network or has failed), the appliance is
removed immediately.

v If the IAACU is able to communicate with the selected appliance, you will be

asked to confirm removal of the appliance before the appliance removal task is
completed. This helps prevent accidental removal of an active and functional
appliance.

Using the Adopt by First Matching Family Function: Use this function to:

14 NAS 200 User’s Reference

v Add an Orphaned Externally Configured Appliance to an appropriate Family.

Appliances that have been configured without using the IAACU tool and that do
not meet the rules for any existing Family are automatically added to the
Orphaned Externally Configured Appliances group. If, after the orphaned
appliance is discovered, you create a Family that is appropriate for the orphaned
appliance, right-click on the orphaned appliance and select Adopt by First
Matching Family to move the appliance from the Orphaned Externally
Configured Appliances group to the newly created Family.

v Move an appliance from one Family to another appropriate Family that occurs

higher in the list of previously defined Families. If there is more than one
appropriate Family for a newly discovered appliance, it automatically appears in
the first appropriate Family in the list of Families. If you want to move a
discovered appliance from one appropriate Family to another appropriate Family:

1. Right-click on the Family that you want the appliance moved to.

2. Select Move Up in List to move the selected Family up in the list of families.
Repeat steps 1 and 2 until the Family that you want to add the appliance to
displays above the Family that currently contains the appliance.

3. Right-click on the appliance that you want to move to another Family and
then select Adopt by First Matching Family.

Universal Manageability Services

The Universal Manageability Services (UM Services) GUI enhances the local or
remote administration, monitoring, and maintenance of IBM systems. UM Services
is a lightweight client that resides on each managed computer system. With UM
Services, you can use a Web browser and UM Services Web console support to
inventory, monitor, and troubleshoot IBM systems on which UM Services is
installed.

This “point-to-point” systems-management approach, in which you use a Web
browser to connect directly to a remote client system, enhances support and
enables you to effectively maintain IBM systems without requiring the installation of
additional systems-management software on your administrator console.

In addition to point-to-point systems-management support, UM Services also
includes support for UM Services Upward Integration Modules. These modules
enable systems-management professionals who use any supported
systems-management platform (including Tivoli Enterprise, CA Unicenter TNG
Framework, and Microsoft Systems Management Server [SMS]) to integrate
portions of UM Services into their systems-management console. Because it was
designed to use industry-standard information-gathering technologies and
messaging protocols, including Common Information Model (CIM), Desktop
Management Interface (DMI), and Simple Network Management Protocol (SNMP),
UM Services adds value to any of these supported workgroup or enterprise
systems-management platforms.

Complete documentation on how to use UM Services is included on the
Documentation CD that came with the appliance.

System requirements

The UM Services client is preinstalled on the NAS 200 appliance. However, you
must have a Web browser installed on your systems-management console. It is
recommended that you set Microsoft Internet Explorer 5.x (or later) as the default
browser.

Chapter 2. Configuration and administration tools 15

Notes:

1. You must install the optional Java Virtual Machine (VM) support to access a
client system running UM Services.

2. If you reinstall Internet Explorer after installing UM Services, you must reapply
the Microsoft VM update. The UM Services client requires Microsoft VM Build
3165 or later. Download the latest Microsoft VM from:

http://www.microsoft.com/java

3. If you install UM Services before you install Microsoft Management Console
(MMC) 1.1 (or a later version), you will not have an icon for Microsoft
Management Console in the IBM Universal Manageability Services section of
your Start menu.

Starting UM Services

You can use IAACU or Terminal Services Client to configure the network setting
remotely, or you can attach a keyboard and mouse to your appliance and configure
the Network settings using the Windows Control Panel. Once you have configured
the network settings for your appliance, you are ready to use UM Services.

To start UM Services:

1. Start your Web browser and then, in the Address or Location field of the
browser, enter:

http://ip_address:1411

where ip_address is the IP address of the NAS 200 and then press Enter.
Or, type:

http://computer_name:1411

where computer_name is the computer name of the NAS 200. The computer
name is predefined as: IBM5194-xxxxxxx, where xxxxxxx is the serial number
located in the lower right corner of the bezel on the front of the appliance.

If you have changed the computer name from the predefined value, use that
name instead. After you have entered the computer name, press Enter.

2. A user log in window displays. Type Administrator in the Username field, and
type password in the Password field. You can leave the Domain field blank.
Make sure the “Save this password in your password list ” checkbox is not
checked, and then click OK.

Note: To ensure system security, change the Administrator password from

“password” to something else. Once you do, or if you create another user
in the Administrator group in the future, use your new
username/password combination instead of the default
username/password combination.

The first time you connect you may be prompted to install XML and Swing
components. Follow the on-screen instructions to install these components and
then close and restart Internet Explorer before you proceed.

3. You are now connected to the NAS 200 through UM Services. In addition to the
standard UM Services functionality, your appliance includes functionality for
administering the appliance, available from the Appliances tab in the left pane of
the UM Services browser. The default view (in the right pane of the UM
Services browser) when you connect to your appliance is Windows 2000 for

16 NAS 200 User’s Reference

NAS. The other selectable view in the Appliances tab is Windows 2000 Terminal
Services, which displays a Terminal Services Web Connection page.

To start Windows 2000 for NAS, click Administer this server appliance in the
right pane of the UM Services browser. To connect to the NAS 200 and manage
it as though you were running Terminal Services Client from your desktop,
select Terminal Services in the Appliances tab of the UM Services browser,
and then follow the instructions for connecting to the NAS 200 using Terminal
Services described in “Terminal Services and the IBM NAS Administration
Console” on page 8.

Launching UM Services from the configuration utility

You can use the IAACU to launch UM Services on your NAS 200 appliance.
Note: The selected appliance must be running Universal Manageability (UM)

Services as a UM Services client. Also, the systems-management console
(the system that is running the IAACU Console) must use a Web browser
that is supported for use with UM Services. If you have not used UM
Services from this system, you will need to install several plug-ins before
proceeding. If you are using an unsupported browser, or if your browser
does not have the necessary plug-ins, you will be notified when you attempt
to launch UM Services on the appliance. For more information on UM
Services, go to:

http://www.ibm.com/pc/ww/software/applications/ums/library.html

To use the IAACU Console to start UM Services on an appliance:

1. Click on the appliance in the IAACU Console Tree View Pane.
When you select the appliance from the tree view, information about the

selected appliance displays in the Information Pane. A Start Web-Based
Management button displays as well.

2. Click Start Web-Based Management.
Your default Web browser starts, loading the UM Services browser

automatically.

3. Log in to the UM Services browser. Refer to step 2 on page 16 for log in
instructions.

For more information on using UM Services to manage your appliances, see the
Universal Manageability Services User’s Guide, included on the Documentation CD
that came with the appliance.

Windows 2000 for Network Attached Storage

You can perform the appliance administration tasks with the Windows 2000 for
Network Attached Storage GUI. You navigate through various administrative task
categories by clicking on the appropriate links on pages or buttons at the top of the
page, and then selecting the task from that category.

Online help is available for Windows 2000 for NAS. This online help can be
accessed in two ways:

1. By clicking the Help button at the top of any Web page. This will display a table
of contents which you can navigate to find help for any Windows 2000 for NAS
task.

2. By clicking the question mark (?) button at the top of any Web page. This will
display context-sensitive help for the task you are currently performing.

Chapter 2. Configuration and administration tools 17

While you can perform most administrative tasks using Windows 2000 for NAS,
there are some advanced tasks for which you must use Terminal Services Client.
See “Terminal Services and the IBM NAS Administration Console” on page 8 for
more information.

You can start Windows 2000 for NAS in one of three ways:

1. Through UM Services, as described in step 3 on page 16.

2. From a Web browser, by entering http://ip_address:8099 or
http://computer_name:8099 and then logging on to the NAS 200.

3. From the NAS 200 desktop while using Terminal Services Client and starting a
browser.

Telnet Server support

CAUTION:
When you Telnet to another machine, your user name and password are sent
over the network in plain, unencrypted, text.

The NAS 200 includes Telnet server capability. The Telnet server provides limited
administrative capability for the NAS 200. This may be useful in cases where you
need to remotely administer the NAS 200, but do not have access to a
Windows-based workstation (from which you could remotely administer the
appliance via a supported Web browser or Terminal Services Client).

SNMP support

You can access the NAS 200 from any Telnet client by specifying the IP address or
hostname of the NAS 200, then logging in using an ID and password (defined on
the NAS 200) with administrative authority. Once you have logged in, you will be
presented with a command-line interface similar to that of a DOS command prompt
in Windows (in fact, it will start at the C:\ prompt). From this interface, you can issue
DOS-like commands (such as dir and cd), and some UNIX-like commands (such
as grep and vi). You can launch some applications, but only character-mode
applications are supported.

By default, the Telnet server is disabled. To enable the Telnet server, from the
Windows 2000 for NAS user interface, go to the Network task group, then select
Telnet. On the Telnet Administration Configuration page that appears, put a check
in the Enable Telnet access to this appliance check box. Later, if you wish to
disable Telnet access, you can uncheck Enable Telnet access to this appliance.If
you do not require Telnet access to the NAS 200, then it is recommended that you
leave the Telnet server disabled.

Support for the Simple Network Management Protocol (SNMP) is enabled. In order
to manage the NAS 200 from your SNMP-capable management application, you will
need to install the Management Information Base (MIB) files for various
components of the NAS 200 on the management application workstation, so that
the application can recognize those SNMP elements (values, alerts, etc.) supported
by the components. Go to www.storage.ibm.com/nas for information on MIB files
that are supported by the NAS 200.
