se500wbk1.book Page 46 Thursday, June 16, 2005 4:19 PM www.dell.com | support.dell.com Assigning Drive Letters and Mount Points A mount point is a drive attached to an empty folder on an NTFS volume. A mount point functions the same as a normal drive but is assigned a label or name instead of a drive letter. Using mount points, a cluster can support more shared disks than the number of available drive letters.
se500wbk1.book Page 47 Thursday, June 16, 2005 4:19 PM 5 In the dialog box, create a partition the size of the entire drive (the default) and then click OK. NOTE: The MSCS software allows only one node to access a logical drive at a time. If a logical drive is partitioned into multiple disks, only one node is able to access all the partitions for that logical drive. If each node must access a separate disk, two or more logical drives must be present in the storage system.
se500wbk1.book Page 48 Thursday, June 16, 2005 4:19 PM www.dell.com | support.dell.com 20 On node 2, open Disk Management. 21 Ensure that the drive letters for node 2 are correct. To modify the drive letters on node 2, repeat step 7 through step 9. Installing and Configuring MSCS MSCS is a software component in Windows 2000 and an integrated service in Windows Server 2003. MSCS performs the basic cluster functionality, which includes membership, communication, and failover management.
se500wbk1.book Page 49 Thursday, June 16, 2005 4:19 PM Creating the Quorum Resource When you install Windows 2000 Advanced Server in your cluster, the software installation wizard prompts you for a location to install the quorum resource. When you install Windows Server 2003 in your cluster, the software installation wizard automatically selects an NTFS disk as the quorum disk, which you can modify later using Cluster Administrator.

se500wbk1.book Page 55 Thursday, June 16, 2005 4:19 PM Installing Your Cluster Management Software This section provides information on configuring and administering your cluster using Microsoft® Cluster Administrator. Microsoft provides Cluster Administrator as a built-in tool for cluster management. Microsoft Cluster Administrator Cluster Administrator is Microsoft's tool for configuring and administering a cluster.
se500wbk1.book Page 56 Thursday, June 16, 2005 4:19 PM www.dell.com | support.dell.com To install Cluster Administrator and the Windows Administration Tools package on a remote console, perform the following steps: 1 Select a system that you wish to configure as the remote console. 2 Identify the operating system that is currently running on the selected system.
se500wbk1.book Page 57 Thursday, June 16, 2005 4:19 PM Using MSCS This section provides information about Microsoft® Cluster Service (MSCS). This section is intended to be an overview of MSCS and provides information about the following: • Cluster objects • Cluster networks • Network interfaces • Cluster nodes • Groups • Cluster resources • Failover and failback For information about specific MSCS procedures, see the MSCS online help.
se500wbk1.book Page 58 Thursday, June 16, 2005 4:19 PM www.dell.com | support.dell.com Preventing Network Failure The Cluster Service uses all available private and public-and-private networks for internal communication. Configure multiple networks as private or public-and-private to protect the cluster from a single network failure. If there is only one such network available and it fails, the cluster nodes stop communicating with each other.
se500wbk1.book Page 59 Thursday, June 16, 2005 4:19 PM • Every node in the cluster is aware of another system joining or leaving the cluster. • Every node in the cluster is aware of the resources that are running on all nodes in the cluster. • All nodes in the cluster are grouped under a common cluster name, which is used when accessing and managing the cluster. Table 5-1 defines various states of a node that can occur in cluster operation. Table 5-1.
se500wbk1.book Page 60 Thursday, June 16, 2005 4:19 PM www.dell.com | support.dell.com Groups A group is a collection of cluster resources with the following characteristics: • All of the resources in the group are moved to the alternate node when one resource in a group fails and it is necessary to move the resource to an alternate node. • A group is always owned by one node at any point in time, and a resource is always a member of a single group.
se500wbk1.book Page 61 Thursday, June 16, 2005 4:19 PM Dependent Resources A dependent resource requires—or depends on—another resource to operate. For example, if a Generic Application resource requires access to clustered physical storage, it would depend on a physical disk resource. A resource can specify one or more resources on which it is dependent; it can also specify a list of nodes on which it is able to run.
se500wbk1.book Page 62 Thursday, June 16, 2005 4:19 PM www.dell.com | support.dell.com Configuring Resource Dependencies Groups function properly only if resource dependencies are configured correctly. The Cluster Service uses the dependencies list when bringing resources online and offline. For example, if a group in which a physical disk and a file share are located is brought online, the physical disk containing the file share must be brought online before the file share.
se500wbk1.book Page 63 Thursday, June 16, 2005 4:19 PM Resource Parameters The Parameters tab in the Properties dialog box is available for most resources. Table 5-3 lists each resource and its configurable parameters. Table 5-3.
se500wbk1.book Page 64 Thursday, June 16, 2005 4:19 PM www.dell.com | support.dell.com Using the Quorum Disk for Cluster Integrity The quorum disk is also used to ensure cluster integrity by performing the following functions: • Maintaining the cluster node database • Ensuring cluster unity When a node joins or forms a cluster, the Cluster Service must update the node's private copy of the cluster database.
se500wbk1.book Page 65 Thursday, June 16, 2005 4:19 PM Adjusting the Threshold and Period Values If the resource DLL reports that the resource is not operational, the Cluster Service attempts to restart the resource. You can specify the number of times the Cluster Service can attempt to restart a resource in a given time interval.
