Server cluster rules

Following these rules will help you solve the most common problems associated with clusters.

  • Windows Server 2003, Enterprise Edition or Windows Server 2003, Datacenter Edition must be installed on each node.

  • All nodes of the cluster must belong to the same Windows Server 2003 family operating systems domain; see Choosing a domain model.

  • When you first create the cluster or add nodes to the cluster, you must be logged on to the domain that has administrative user rights and permissions on all nodes.

  • Each cluster node can belong to only one cluster.

  • The shared drive must be formatted using the NTFS file system.

  • Cluster disks on a shared bus must be partitioned as master boot record (MBR) and not as GUID partition table (GPT) disks.

  • Do not change the computer name of a cluster node after configuring the first node of your cluster.

  • Do not repartition disks on the shared bus without first deleting the corresponding disk resources.

  • If you start the node using an operating system other than Windows Server 2003, Enterprise Edition or Windows Server 2003, Datacenter Edition, do not run any diagnostic tools that make low-level writes to a physical disk.

  • Do not reassign the drive letters of the system disks on the nodes.

  • Verify that either the WINS or DNS service is accessible from all nodes.

  • Verify that TCP/IP is installed on all nodes and clients.

  • Verify that all cluster nodes can detect one another over the network. Use the TCP/IP ping utility or the Windows Server 2003 family operating system net view command.

  • Check all event logs on all affected computers for error messages.
