Roadmap for setting up and configuring the NAS Gateway 300
A suggestion for first-time users...
Your understanding of the NAS Gateway 300 and your ability to use it will be
greatly enhanced if you first proceed to the NAS Setup Navigator tutorial.
The NAS Setup Navigator maps out the initial configuration tasks and leads
you through the tasks in the proper order. The tool detects which NAS
appliance it is running on and adjusts the menu and content appropriately. You
can follow links to more in-depth information and to the configuration panels
used to perform the steps. You can also tailor the instructions to fit your needs
by selecting optional topics. The Navigator not only presents information on
functions and features–such as clustering–but also allows you to enable the
functions and features. To start the NAS Setup Navigator, click on the NAS
Setup Navigator icon on the desktop.
After you have become familiar with the NAS Gateway 300, you can refer to
this book for more details.
The following roadmap presents the requirements and instructions for setting up
and configuring the NAS Gateway 300. Following these directions and referring to
the appropriate sections of this book will help you in this task.
Prerequisites
vA 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.
Figure 1. Opening screen of the NAS Setup Navigator
Chapter 1. Introduction 3

vAll Windows shared disks must be defined as basic. Windows 2000
dynamic disks are not supported.
vA Quorum drive must be available to both nodes and have the same
drive letter on each node.
vAll disks shared between the two cluster nodes must have the same
drive letter.
vAll shared storage must be defined as NTFS and be on primary
partitions.
vCompression cannot be enabled on any disk partition.
vEach node must have one private and one public adapter.
Cluster setup requirements
See “Cluster setup requirements” on page 6.
Configuration and administration tools
The NAS Gateway 300 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 NAS
Gateway 300 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 13 for information on managing this
device using a keyboard, display, and mouse. For “headless” management
of the NAS Gateway 300, you can use one of the following tools:
vTerminal Services, for remote configuration and management from
another device on the network
vUniversal Manageability Services (UMS) for management through a Web
browser
vWindows 2000 for NAS, a Web-based GUI for those not familiar with the
Windows desktop
vIBM Advanced Appliance Configuration Utility (IAACU) for setup and
configuring multiple devices or other appliances on a single network
After you determine how you will manage the NAS Gateway 300, you can
begin setup and configuration of the device.
For more information on configuration and administration tools, see
Chapter 3, “Configuration and administration tools” on page 13.
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 2, “Getting
started” on page 9.
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:
vIf 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.
4NAS Gateway 300 User’s Reference

vIf 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 10 and
“Setting up the network” on page 11.
Step 2 - Define storage and setup partitions
The NAS Gateway 300 attaches to your SAN-attached storage device,
through the Fibre Channel, and provides your Ethernet LAN-attached clients
access to that storage. You must define storage arrays and logical drives on
the SAN-attached storage device and set up Windows partitions on the
logical drives as defined in Chapter 4, “Setting up storage” on page 27.
For more information on defining storage and setting up partitions, see
Chapter 4, “Setting up storage” on page 27.
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 33. Note the cautionary statement
at the beginning of that section.
b. Domain setup
See “Joining a node to a domain” on page 36.
3. Shut down the first node (see “Shutting down and powering on the NAS
Gateway 300” on page 87 for more information on shutting down the
NAS Gateway 300).
4. Power on the other node (the joining node).
5. Set up the joining node:
a. Networking setup
See “Networking setup” on page 33.
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 “Fibre Channel adapter” on page 104 to diagnose
the problem.
c. Domain setup
See “Joining a node to a domain” on page 36.
d. Shut down the joining node (see “Shutting down and powering on
the NAS Gateway 300” on page 87 for more information on shutting
down the NAS Gateway 300).
6. Power on the first node and complete “Cluster setup” on page 39.
7. Power on the joining node and complete “Cluster setup” on page 39.
For more information on network setup and cluster installation, see
Chapter 5, “Completing networking, clustering, and storage access setup”
on page 33.
Chapter 1. Introduction 5

Step 4 - Cluster administration
At this point you can add users, file shares, and complete other
configuration tasks to improve operations of the NAS Gateway 300 in a
cluster environment.
1. Add users (see “Creating users” on page 42).
2. Add file shares (see “Creating clustered file shares (CIFS and NFS)” on
page 50). 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 66) 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 “Shutting down and powering on the NAS Gateway 300” on page 87 to
ensure system integrity.
For more information, see Chapter 6, “Managing and protecting the network
and storage” on page 55.
Cluster setup requirements
Before you configure the NAS Gateway 300 nodes for clustering, ensure that the
following requirements are met:
Network requirements
vA unique NetBIOS cluster name.
vYou 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 8 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 NAS Gateway 300 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.
