Providing LUN Access to a Server Cluster

  • Article

Applies To: Windows Server 2003 R2

With Storage Manager for SANs, you can provide LUN access to a group of servers (a server cluster) in your 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 members. For more information, see Clustering Services at the Microsoft Web site (https://go.microsoft.com/fwlink/?LinkId=50520).

To provide LUN access to a server cluster

  1. In LUN Management, click Manage Server Connections.

  2. In the Manage Server Connections dialog box, click Manage Clusters.

  3. In the Manage Clusters dialog box, click Add.

  4. 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.

  5. 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 "Task 1: Configure Server Connections" earlier in this guide.

  6. Click OK to create the new cluster, and click OK again to go back to the Manage Server Connections dialog box.

  7. 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 the iSCSI initiator adapters of each individual server included in the cluster by selecting the server from the list. All of the configuration changes you make on the individual servers will take effect on the cluster.

  8. After server clusters are created, LUNs can be assigned to them in the same way they are assigned to individual servers.

Warning

If you are going to enable more than one connection (Fibre Channel ports and/or iSCSI initiator adapters) between a server cluster and a LUN, and the cluster 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" earlier in this guide.
