    Virtual Servers and Resource Groups In a cluster environment, you do not access a physical server; you access a virtual server, which is managed by MSCS. Each virtual server has its own IP address, name, and hard drive(s) in the shared storage system.

  • Page 11: Shared Storage Systems

    See "Quorum Disk (Quorum Resource)" and the MSCS online documentation for more information. NOTE: PowerEdge Cluster SE500W solutions do not support the Majority Node Set (MNS) Quorum resource type. Shared Storage Systems Cluster nodes can share access to external storage systems; however, only one of the nodes can own any RAID volume in the external storage system at any time.

  • Page 12: Storage System

    NOTE: MSCS and Network Load Balancing (NLB) features cannot coexist on the same node, but can be used together in a multitiered cluster. For more information, see the Dell PowerEdge Clusters website at www.dell.com/ha or the Microsoft website at www.microsoft.com.

    This warning message alerts you to the possibility of data loss if certain precautions are not taken to protect the integrity of the data on your cluster. NOTICE: To prevent data loss, your cluster must meet the conditions in the following bulleted list before you attempt any data-destructive operation on your shared hard drives.

  • Page 45: Configuring And Managing Virtual Disks

    NOTE: Dell recommends that you use a RAID level other than RAID 0 (which is commonly called striping). RAID 0 configurations provide very high performance, but do not provide the level of availability required for the quorum resource. See the documentation for your storage system for more information about setting up RAID levels for the system.
  • Page 46 Drive letters A through D are reserved for the local system. The number of drive letters required by individual servers in a cluster may vary. Dell recommends that the shared drives be named in reverse alphabetical order beginning with the letter z.
  • Page 47 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.

  • Page 48: Installing And Configuring Mscs

    NOTE: In Windows Server 2003, mapping a network drive to the same drive letter as a cluster disk resource renders the cluster disk inaccessible from Windows Explorer on the host. Ensure that mapped network drives and cluster disks are never assigned the same drive letter.

  • Page 49: Creating The Quorum Resource

    To properly identify the quorum resource, Dell recommends that you assign the drive letter Q to the quorum resource partition. Dell does not recommend using the remainder of the virtual disk for other cluster resources. If you do use the space for cluster resources, be aware that when you create two volumes (partitions) on a single virtual disk, they will both fail over together if a server fails.

    This tracking system allows you to view the state of all cluster network interfaces from a cluster management application, such as Cluster Administrator. Cluster Nodes A cluster node is a system in a server cluster that has a working installation of the Windows operating system and the Cluster Service. Cluster nodes have the following characteristics: •...

  • Page 59: Forming A New Cluster

    • 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.

  • Page 60: Groups

    • Can be brought online and taken offline • Can be managed in a server cluster • Can be hosted (owned) by only one node at a time To manage resources, the Cluster Service communicates to a resource Dynamic Link Libraries (DLL) through a Resource Monitor.

  • Page 61: Dependent Resources

    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.

  • Page 62: Configuring Resource Dependencies

    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.

  • Page 64: Resource Failure

    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.

  • Page 65: Creating A New Resource

    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. If the Cluster Service exceeds the maximum number of restart attempts (Threshold value) within the specified time period (Period value), and the resource is still not operational, the Cluster Service considers the resource to be failed.

  • Page 66: Deleting A Resource

    Share subdirectories — Publishes several network names—one for each file folder and all of its immediate subfolders. This method is an efficient way to create large numbers of related file shares on a single file server. For example, you can create a file share for each user with files on the cluster node.

  • Page 67: Configuring Active And Passive Cluster Nodes

    Configuring Active and Passive Cluster Nodes Active nodes process application requests and provide client services. Passive nodes are backup nodes that ensure that client applications and services are available if a hardware or software failure occurs. Cluster configurations may include both active and passive nodes. NOTE: Passive nodes must be configured with appropriate processing power and storage capacity to support the resources that are running on the active nodes.
  • Page 68 After failover, the Cluster Administrator can reset the following recovery policies: • Application dependencies • Application restart on the same cluster node • Workload rebalancing (or failback) when a failed cluster node is repaired and brought back online Failover Process The Cluster Service attempts to fail over a group when any of the following conditions occur: •...

  • Page 69: Failback

    The Cluster Service continues to try and fail over a group until it succeeds or until the number of attempts occurs within a predetermined time span. A group’s failover policy specifies the maximum number of failover attempts that can occur in an interval of time. The Cluster Service will discontinue the failover process when it exceeds the number of attempts in the group’s failover policy.
