Dell 4200 Uninstalling Microsoft Cluster Server, Removing a Node From a Cluster, Cluster Service

Cluster Service

The Cluster Service performs most of the cluster functionality, including membership management, communication management, and fail-over manage- ment. When the Cluster Server has been properly installed, the Cluster Service is started on each node and is activated automatically in the event that one of the nodes fails or goes off-line.

To verify that the Cluster Service is running on a cluster node, click the Start button, point to Settings, and then click Control Panel. Double-click the Services icon. The Cluster Service should be indicated in the dialog box. Check to make sure that the Cluster Service is running on the second node also.

Availability of Cluster Resources

In the context of clustering, a resource is a basic unit of fail-over. Applications are made up of resources that are grouped together for the purposes of recovery. All recov- ery groups, and therefore their comprising resources, must be online (or in a ready state) for the cluster to func- tion properly.

To verify that the cluster resources are online, start the Cluster Administrator on the monitoring node. Click the Start button, point to Programs, point to Administrative Tools (Common), and then click Cluster Administrator. Open a connection to the cluster and observe the running state of each recovery group. If a group has failed, one or more of its resources may be off-line.

Troubleshooting the reasons that resources might be fail- ing is beyond the scope of this document, but examining the properties of each resource and ensuring that the specified parameters are correct is a first step in this pro- cess. In general, if a resource is off-line, it can be brought online by selecting it, right-clicking it, and choosing Bring Online from the pull-down menu. For information about troubleshooting resource failures, refer to the Microsoft Windows NT Enterprise Edition Administra- tor’s Guide and Release Notes .

Uninstalling Microsoft Cluster Server

Before you can uninstall Cluster Server from a node, you must do the following:

1.Take all resource groups off-line or move them to the other node.

2.Evict the node from the cluster by right-clicking the node icon in Cluster Administrator and selecting Evict Node from the menu.

3.Close Cluster Administrator on the node.

4.Stop the Cluster Service running on the node.

5.Uninstall Microsoft Cluster Server using the Add/ Remove Programs utility in the Control Panel group.

Removing a Node From a Cluster

WARNING: The power supplies in this computer system produce high voltages and energy hazards, which can cause bodily harm. Only trained service technicians are authorized to remove the computer covers and access any of the components inside the computer.

WARNING: This system may have more than one power supply cable. To reduce the risk of electrical shock, a trained service technician must disconnect all power supply cables before servicing the system.

When removing a node from a cluster, it is important to power down the node before removing any of the cluster cabling. Likewise, when rejoining a node to a cluster, all cables must be attached before the node is powered up.
