Running Applications on a Cluster

This section provides general information about con- figuring and running applications software on the PowerEdge Cluster. To configure applications software, click the Start button, point to Programs, point to Admin- istrative Tools (Common), and then click Cluster Administrator. In Cluster Administrator, open a connec- tion to the cluster.

Before you start Cluster Administrator on either cluster node, make sure the Cluster Service has been started and a cluster has been formed. You can verify this by using the Event Viewer and looking for events logged by ClusSvc. You should see either of the following events:

Microsoft Cluster Server successfully formed a cluster on this node.

or

Microsoft Cluster Server successfully joined the cluster.

Setting Up Applications Software to Run on the Cluster

Setting up applications software to run on a cluster means establishing them as a group of cluster resources. Cluster resources are created using the New Resource wizard.

The process of creating resources involves the following:

•The type of resource must be specified.

•The possible owners of the resource must be selected (the default is both nodes).

•The dependencies of the resource must be determined.

•The resource-specific parameters must be defined.

After a resource has been created, it must be brought online for access by the cluster nodes and clients.

The following subsections outline the creation and setup of three example cluster resources:

•Internet Information Server (IIS) service

•File-sharing service

•Print-spooling service

These examples are provided here to instruct you in set- ting up cluster resources using real applications software. Refer to the Microsoft Windows NT Cluster Server Administrator’s Guide for more detailed information and instructions about creating cluster resources.

Internet Information Server Service

The IIS Virtual Root is one of the Microsoft Cluster Server resource types that can be used to provide fail- over capabilities for virtual root directories of IIS version

3.0or later. The IIS Virtual Root depends on three other types of resources (disk, Internet Protocol [IP] address, and network name resources); these resources will be placed in the same recovery group.

The following example procedure describes how to set up the IIS Virtual Root service. This procedure assumes that IIS has already been installed.

1.Start the New Group wizard by right-clicking any group or resource in the Cluster Administrator, then point to New, and then select Group from the submenu.

2.In the dialog box, type Web Service for the new group name.

You may also want to select one of the cluster nodes as the preferred owner of the group.
