Disclaimer: At the time this book was written, the final release of the NAS
Gateway 500 code was not available yet. Because we were working with the
prerelease code, it is possible that there may be some differences as
compared to the final product.

Connect the cables as described in 9.3.1, “Our cluster topology” on page 205.
Connect the integrated Ethernet port 1 of node 1 to the network in which your PC
resides.
Make sure that the Initial Configuration wizard on both nodes has not been run
before.
Power on both nodes, and wait until both nodes have their IP addresses
displayed on the LCD operator panel.
If the WebSM Remote Client is not installed on your PC, follow the steps
described in 7.4.2, “Web-based System Manager Remote Client installation” on
page 123 to install it. Use the IP address displayed on the LCD operator panel of
node 1.
Start the WebSM Remote Client. In the Host name field, fill in the IP address
displayed on the LCD operator panel of node 1. Fill in the root in the User name
field. Fill in the password in the Password field. After that, press Enter or Tab and
wait for the connection to be established.
Start the Initial Configuration wizard as described in 7.4.4, “Initial Configuration
wizard” on page 131. Click Next to continue.
Important: The four Ethernet ports connecting to the client network must be
on the same VLAN.
Important: You should not connect the node 2 integrated Ethernet port 1 to
the client network unless you have a DHCP server on the network. If there is
no DHCP server, both nodes will be assigned the same IP address on port 1,
which will result in an IP address conflict if both nodes are connected.
Chapter 9. Cluster configuration 213
As shown in Figure 9-4, select Clustering. Because what we are constructing is
not a geographical cluster,
do not select Remote Mirroring. If the CIFS feature
has been purchased, select CIFS File Serving. Click Next to continue.
Figure 9-4 Select the clustering feature
The date and time settings panel will appear, as shown in Figure 7-22 on
page 134. Enter the proper date and time settings, then click Next to continue.
The root password panel will appear, as shown in Figure 7-23 on page 135.
Enter the new root password twice and click Next to continue.
The NAS Administrators panel will appear, as shown in Figure 7-24 on page 136.
We add user nasadmin here as a NAS administrator account. This administrator
account will be added to both nodes. Click Next to continue.
The directory service panel will appear, as shown in Figure 7-27 on page 138.
Click Next to continue.
214 The IBM TotalStorage NAS Gateway 500 Integration Guide
The File Access Users panel will appear, as shown in Figure 9-5 below. File
Access Users are cluster aware, and if they exist, they should be added here.

Chapter 9. Cluster configuration 215
The Cluster wizard starts here, as shown in Figure 9-6. Fill in the Cluster name,
Node 1 host name, and Node 2 host name field. If you want to configure Link
Aggregation for your cluster configuration, click Configure Link Aggregation.
Please see “Configuring Link Aggregation” on page 152 for more information
about Link Aggregation. Otherwise, click Next to continue.
