Define a Server Cluster in Storage Manager for SANs
Applies To: Windows Server 2003 R2
With Storage Manager for SANs, you can provide logical unit number (LUN) access to a group of servers (a server cluster) in your storage area network (SAN). Server clusters are created by defining them in Storage Manager for SANs and by enabling clustering services on each individual server in the cluster.
Warning
To prevent data loss, make sure that each server is a member of only one cluster and that clustering services are running on all cluster nodes. For more information about clustering services, see Clustering Services at the Microsoft Web site.
After server clusters are created, you can assign LUNs to them in the same way you assign LUNs to individual servers.
To define a server cluster in Storage Manager for SANs
In LUN Management, click Manage Server Connections.
In the Manage Server Connections dialog box, click Manage Clusters.
In the Manage Clusters dialog box, click Add.
In the Add New Cluster dialog box, type a name for the cluster and optionally, type a general description that will help you identify the cluster.
From the server list, select all the servers that you want to include in the new cluster.
Note
To add servers to a cluster you must first add them to the server list in Manage Server Connections. For more information see Manage Server Connections.
Click OK to create the new cluster.
Click OK again, to go back to the Manage Server Connections dialog box.
The new cluster will now be listed in the Manage Server Connections dialog box. To configure the connections of the cluster, configure the Fibre Channel ports or iSCSI initiator adapters of each individual server included in the cluster by selecting the server from the list. All configuration changes you do on individual servers will take effect on the cluster.
Warning
If you are going to enable more than one connection (Fibre Channel ports and/or iSCSI initiator adapters) on a server in the cluster, and that server is not configured to use Multipath I/O, data corruption can occur. For more information about Multipath I/O, see Support for Multipath I/O (MPIO).
