Chapter 5. Completing networking, clustering, and storage
access setup
Note: Before proceeding with the steps in this chapter, configure the shared
storage using the Storage Manager application. See “Chapter 4. Setting up
storage” on page 29 for details.
The Model 326 uses Microsoft Cluster Server (MSCS) software to provide clustering
technology for your storage. Clustering ensures availability of the storage,
regardless of individual component failure.
After installing the clustering function, you can use Cluster Administration to set up
the failover function. Then, if a node or a node’s component were to fail, the Model
326 detects the failure and begins a failover process in less than 10 seconds, and
completes the process within 60 seconds. Failover/Failback includes Active/Active
support for the CIFS and NFS protocols.
Active/Active support is available for HTTP and FTP. See the online cluster
administration guide for this procedure.
Novell NetWare and Apple Macintosh shares are available on both nodes, but not
through clustering services. If either node fails, the shares become unavailable until
the node is brought back up.
This chapter gives the details for installing and initially configuring MSCS on the
Model 326. Administrative concepts and procedures are provided in the online help
and at the following Web sites:

Networking setup
Attention: Before you install cluster services on the first node, make sure that the
joining node is powered off. This is required to prevent corruption of data on the
shared storage devices. Corruption can occur if both nodes simultaneously write to
the same shared disk that is not yet protected by the clustering software.
Configuring the interconnect (private) network adapter
To configure the interconnect (private) network adapter, perform the following steps
on both nodes. The
Private connection is the “heartbeat” interconnect for the
cluster.
1. Right-click My Network Places and then select Properties .
2. Select the network connection that uses the IBM Netfinity 10/100 Ethernet
Adapter.
3. Right-click the adapter icon and click Properties .
4. Click Configure , select the Advanced tab, and verify that the following
characteristics are set:
Link speed and Duplex 100 Mbps / Full Duplex
5. Click OK .
6. If prompted to restart the node, select No .
