2 Model 326 User’s Reference
Roadmap for setting up and configuring the Model 326
A suggestion for first-time users...
Your understanding of the Model 326 and your ability to use it will be greatly
enhanced if you first proceed to the NAS Setup Navigator tutorial.
The NAS Setup Navigator is a distillation of the tasks you will need to
complete to set up and configure the Model 326 and get it up and running.
The Navigator not only presents information on functions and features -- such
as clustering -- but also allows you to enable the functions and features.
After you have become familiar with the Model 326, you can refer to this book
for more details.
The following roadmap presents the requirements and instructions for setting up
and configuring the Model 326. Following these directions and referring to the
appropriate sections of this book will help you in this task.
Prerequisites
v A domain controller must exist on the network and a login ID must be
defined for each node to log on. Each node must join the same domain.
v All Windows shared disks must be defined as basic. Windows 2000
dynamic disks are not supported.
v A Quorum drive must be available to both nodes and have the same
drive letter on each node.
v All disks shared between the two cluster nodes must have the same
drive letter.
v All shared storage must be defined as NTFS and be on primary
partitions.
v Compression cannot be enabled on any disk partition.
v Each node must have one private and one public adapter.
Cluster setup requirements
See “Cluster setup requirements” on page 6.
Configuration and administration tools
The Model 326 is a network-attached storage appliance that has several
different methods of configuration depending on your environment.
First, determine how you will manage the device. You can manage the
Model 326 in “headless” mode or with a keyboard, display, and mouse
directly attached to each node. See “Using a keyboard, monitor, and mouse
for setup and configuration” on page 9 for information on managing this
device using a keyboard, display, and mouse. For “headless” management
of the Model 326, 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
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
Chapter 1. Introduction 3
After you determine how you will manage the Model 326, you can begin
setup and configuration of the device.
For more information on configuration and administration tools, see
“Chapter 2. Configuration and administration tools” on page 9.
Step 1 - Initial network setup
Configure both nodes to enable access over the network. The general steps
to do this are given below. More details are given in “Chapter 3. Getting
started” on page 25.
1. Use Dynamic Host Configuration Protocol (DHCP) or static addressing
to set up one public network connection in each node.
a. If you are operating with a keyboard, display, and mouse, set up a
public network connection to access the device.
b. If you are operating in a headless environment, use one of the
following methods:
v If DHCP is installed and the IP address requested can be
determined, you can use DHCP 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.
2. Complete the steps in “Setting the date and time” on page 27 and
“Setting up the network” on page 27.
Step 2 - Define shared storage and setup partitions
The Model 326 comes with preconfigured shared storage spanning nine
disks. The storage is formatted as an array, at RAID-level 5, consisting of
the following logical unit numbers (LUNs):
v A LUN of 500 MB, for the Quorum drive (drive letter G)
v A second LUN, composed of the remaining space and used as a shared
drive with one built-in hot spare
To use this default, preconfigured storage, validate all storage areas and
determine that the drive letters are the same on each node.
Otherwise, from one of the two nodes, define all storage arrays using
Storage Manager and then set up Windows partitions as defined in
“Chapter 4. Setting up storage” on page 29.
Attention: When you set up the shared storage, you must configure the
storage on one node only. During the setup of shared storage, leave the
joining node powered off.
Step 3 - Complete network setup and cluster installation
1. Power on either node. (This becomes the first node.)
2. Set up the first node:
a. Networking setup
See “Networking setup” on page 37. Note the cautionary statement
at the beginning of that section.
b. Domain setup
See “Joining a node to a domain” on page 40.
4 Model 326 User’s Reference
3. Power off the first node.
4. Power on the other node (the joining node).
5. Set up the joining node:
a. Networking setup
See “Networking setup” on page 37.
b. Shared storage setup
For the joining node, the only part of this step that you must
complete is assigning drive letters on the shared storage; make sure
that the drive letters are the same as those on the first node.
Also, if you have trouble with the Fibre Channel connection, you can
use the steps in “Testing the Fibre Channel host adapter with FAStT
MSJ” on page 108 to diagnose the problem.
c. Domain setup
See “Joining a node to a domain” on page 40.
d. Power off the joining node.
6. Power on the first node and complete “Cluster setup” on page 40.
7. Power on the joining node and complete “Cluster setup” on page 40.
For more information on network setup and cluster installation, see
“Chapter 5. Completing networking, clustering, and storage access setup”
on page 37.
Step 4 - Cluster administration
At this point you can add users, file shares, and complete other
configuration tasks to improve operations of the Model 326 in a cluster
environment.
1. Add users (see “Creating users” on page 43).
2. Add file shares (see “Creating clustered file shares (CIFS and NFS)” on
page 47). Note that you must configure Server for NFS before NFS file
sharing can be used.
For more information on cluster administration, see “Configuring clusters” on
page 41.
Step 5 - Additional functions
Additional functions are available for backup, persistent images, and adding
more storage areas. It is recommended that after you complete the setup
and configuration procedures, you use the Persistent Storage Manager
Disaster Recovery option (“Disaster Recovery” on page 64) or other method
to back up the system configuration in the event of a failure.
Also, it is imperative to use the system shutdown procedure described
in “Powering off and powering on the Model 326” on page 49 to ensure
system integrity.
For more information, see “Chapter 6. Managing and protecting the network
and storage” on page 53.
Chapter 1. Introduction 5
Cluster setup requirements
Before you configure the Model 326 nodes for clustering, ensure that the following
requirements are met:
Network requirements
v A unique NetBIOS cluster name.
v You will need at least seven static IP addresses: five for the node and
cluster setup, and two for each file share served by the cluster. A formula
for the number of static IP addresses is:5+(2xnumber_of_file shares).
The IP addresses required for node and cluster setup are:
– At least three unique, static IP addresses for the public network: one
for each node (for client access through the PCI NIC adapter) and
one for the cluster itself (the administration IP address).
Table 1 on page 7 shows a summary of the networking information
necessary for the public connection.
– Two static IP addresses for the cluster interconnect on a private
network or crossover, through the onboard Ethernet adapter. The
default IP addresses for the private network adapters are 10.1.1.1 for
the first node in the cluster, and 10.1.1.2 for the node that joins the
cluster. (The top node in the Model 326 is considered the first node,
and the bottom node is considered the joining node.)
Notes:
1. If you are not the system administrator, contact that person for the
applicable IP addresses.
2. Each node in a cluster must join the same domain and be able to
access a Primary Domain Controller (PDC) and DNS server, but it is not
required that the nodes log into the domain.
3. Each node in the cluster must have at least two network adapters: at
least one for the public network and the other for the private
interconnect.
Shared disk requirements
Powering off and powering on the Model 326
6 Model 326 User’s Reference
v All shared disk arrays and devices, including the quorum disk, must be
physically attached to a shared storage bus.
v All shared disks must be configured as basic (not dynamic) disks.
v All shared disks must have the same drive letter on each node.
v All partitions on these disks must be formatted with NTFS.
v All partitions on these disks must also be Primary Partitions.

Terminal Services Client
The Terminal Services Client, when installed on a workstation that is
attached to the same network as the Model 326, enables you to remotely
administer the appliance using the Model 326 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 12 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.
After the appliance is detected by the IAACU Console, you can use the
IAACU to:
v Set up and manage the network configuration for the appliance, including
assigning the IP address, default gateway, network mask, and DNS
server to be used by the appliance. (See the note in “Setting up the
network” on page 27, regarding the Ethernet adapter that is integrated on

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 23.
2. By using the Terminal Services Client software.
Installing Terminal Services
To use the Terminal Services Client, complete the following steps to install it on the
remote workstation and connect to the Model 326 appliance:
1. Insert the Supplementary CD into the workstation CD-ROM drive.
2. Select Start → Run.
3. In the Open field, type (with quotation marks)
"x:\Terminal Services Client\Disk 1\setup.exe"
where x is the drive letter assigned to the CD-ROM drive.
4. Click OK to begin the Terminal Services Client Setup program.
5. Accept the defaults in each window that opens or refer to the Microsoft
Windows documentation for more instructions.
6. When the Terminal Services Client Setup program completes, ensure that the
workstation has network-connectivity to the NAS appliance so that you can
administer the appliance.
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 appropriate Model 326. If
that Model 326 is not listed, enter the IP address or the computer name of the
Model 326. The computer name is predefined as IBM5195-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.
Note: Although you can do so, it is recommended that you not change the
default computer name to avoid the chance of propagating
misidentification through the system. And, if you are using IBM Director
to manage your appliance, and you change the default name, the default
name continues to appear in IBM Director.
3. For Size, select a screen size in which the Model 326 desktop will appear. It is
recommended that you choose a size other than full screen.
4. Click Connect to start the Terminal Services Client session. A user login window
appears.
5. Log in. Type Administrator in the Username field, type password in the
Password field, and then click OK to log in. After you log in, you can begin
using Terminal Services Client to configure and manage the Model 326, as if a
keyboard, mouse, and monitor were directly attached to it. The Model 326
desktop contains a shortcut, titled IBM NAS Admin, to a special console, the
IBM NAS Administration console.
12 Model 326 User’s Reference
IBM NAS Administration console

To determine this information:
1. Start a Windows Terminal Services session from the administrator’s console to
the Model 326.
2. Click the IBM NAS Admin icon on the desktop.
3. In the left pane, click File Systems → Shared Folders → Sessions.
4. The users currently using the storage are displayed. To close those sessions,
use a right-click. Before you close a session, notify the user that you are going
to close the session by clicking Start → Programs → Accessories → Command
Prompt, and then issuing the net send hostname messagetext command.
IBM Advanced Appliance Configuration Utility
Note: Although you can do so, it is recommended that you not change the default
computer name of your NAS appliance to avoid the chance of propagating
misidentification through the system. Also, The IBM Advanced Appliance
Configuration Utility depends on the original name to function.
The IBM Advanced Appliance Configuration Utility (IAACU) helps you to set up and
reconfigure the network configuration on the Model 326 appliance, as well as other
IBM appliances. The IAACU agent, preinstalled on the Model 326 appliance, works
with the IAACU Console, a Java-based application that is installed on a
network-attached system. You can use the IAACU as a systems-management
console to automatically detect the presence of Model 326 appliances on the
network. After the Model 326 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
Model 326.
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
Chapter 2. Configuration and administration tools 13
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 IAACU configures and reports the TCP/IP settings of the first adapter
(excluding the integrated Ethernet controller that is used for the interconnection
of the two engines) on each appliance. The “first” adapter is defined by its
position: if there is an adapter in slot 2, it is the first adapter; if there is an
adapter in slot 3, it is the first adapter.
Be sure to connect the first adapter to the same physical network as your
systems-management console. You can do this in one of two ways:
v Manually configure the network adapter to be on the same subnetwork as the
systems-management console.
v Create a Family that assigns the network adapter to the same subnetwork as
the systems-management console. See “Using Families and Groups in the
Tree View” on page 17 for more details. Note that the values for Min IP
address, Max IP address, Subnet Mask, and Default Gateway must be in the
same range that the IAACU is configured.
2. The IAACU must be running to configure newly installed appliances
automatically.
3. The system running the IAACU 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
IAACU, delete this file, and then restart the utility. This deletes all previously
configured Families. However, the IAACU will automatically discover connected
appliances and their network settings.
Initial network adapter selection and connection to the IAACU
Unlike the limited number of network adapter placement options in the previous
release, in this release there are an increased number of network adapter types
and/or locations from which you can connect. Assuming you have a keyboard and
monitor attached, perform the following steps to take into account the new adapter
placement options:
1. Decide which adapter will be used to connect to the IAACU, and connect the
appropriate cable type.
2. Open the Network and Dial-up Connections panel. (From the desktop, right-click
My Network Places, and select Properties.)
3. Determine the connection name of the adapter you have selected to use. Move
the mouse cursor over the adapter name, and a description of the adapter type
will appear. If this is inconclusive, right-click the adapter, and select Properties.
Under the General tab, click the Configure button. The line which contains the
location information will provide the adapter’s slot location. For example,
Location 1 means the adapter is in PCI slot number 1. Close the adapter
properties panel.
4. On the Network and Dial-up Connections menu bar, select Advanced and then
Advanced Settings. From the Connections menu, select the adapter’s
connection name. Then using the down arrow, move the selection down to the
next-to-last position in the list. (The last entry in the list should be the remote
access connections, shown as the telephone icon.) Save your changes by
clicking OK.
5. The IAACU will now detect the appliance using the adapter you have just
enabled.
14 Model 326 User’s Reference
IAACU Agent
IAACU Console
The IAACU agent is preinstalled on the Model 326 appliance.
After you connect the Model 326 to your network, the IAACU agent automatically
reports the appliance serial number and type, the MAC address of its onboard
Ethernet controller, and whether DHCP is in use by the appliance. Furthermore, it
reports the host name, primary IP address, subnet mask, primary DNS server
address, and primary gateway address if these are configured on the system.
Note: The IAACU agent periodically broadcasts the appliance IP settings. To
prevent the service from broadcasting this data periodically, stop the
iaaconfig service.
The IAACU Console is a Java application that you install on one system in your
network for use as a systems-management console. For information on how to
install the IAACU Console, see Table 23 on page 126.
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 Model 326 appliances, as well as other IBM appliances
that run the IAACU agent and are attached to the same physical subnet as the
IAACU Console.
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 host names.
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.
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:
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 Model 326 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 any item in the Tree View, information about that
item (and any items that are nested below that item in the tree view) appears in
the Information Pane.
v The Information Pane
The Information Pane, located on the right side of the IAACU Console, displays
information about the item that is currently selected in the Tree View Pane. The
information that appears 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,
Chapter 2. Configuration and administration tools 15
host name, serial number, and so on) about each of the Model 326 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:
File Use the File menu to import or export the IAACU Console configuration
data, to scan the network, or to exit the program.
Family
Use the Family menu to add or delete Families, or to move Families up or
down in the tree view.
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.
Help Use the Help menu to display product information.
Discovering Model 326 Appliances
Any Model 326 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 appears in two locations in the tree view:
v Every discovered appliance is listed in the tree view under All Appliances.
v Each discovered appliance also appears in one of the following sections of the
tree view:
– In a Family
If the discovered appliance fits the requirements of a Family, it will
automatically appear as part of a Family.
Notes:
1. 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 17.
2. If the Model 326 cannot be discovered by the IAACU console, check the
IP and subnet addresses of the Model 326 and the computer that is
running the IAACU console.
– In the Orphaned Appliances group
If the discovered appliance does not fit a previously configured Family, it is
placed in the Orphaned Appliances group.
– In the Orphaned Externally Configured Appliances group
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 19.
16 Model 326 User’s Reference
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 Panel 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 appear in the Information Pane.
If you select an appliance from a Family in the Tree View Pane, the selected
appliance network settings appear 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 the IP address range for the Family 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 noncontiguous 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
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 a
Family and then select Move Up or Move Down to adjust its position within the
Families list.
v Orphaned Appliances
Chapter 2. Configuration and administration tools 17
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 the
orphaned appliance and select Adopt by First Matching Family. For more
information, see “Using the Adopt by First Matching Family function” on page 19.
Note: The IAACU does 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 does 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 opens.
2. Select Appliance Family Rules.
The Appliance Family Rules determine what purpose an appliance must serve
to be included in the Family. Select one of the following values:
v IBM TotalStorage NAS Appliances
v IBM xSeries 130 and 135
3. Type the name that will be used for this Family in the Family Name field.
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, clear the Use DHCP check
box and fill in the following fields:
