Microsoft Cluster Server relies heavily on the underlying components
- Local and shared storage -Multi-homed networks Fibre Channel, SSA, or ServeRAID Systems management software -Microsoft Cluster Administrator -IBM Cluster Systems Manager ICSM Microsoft Cluster Server relies heavily on properly configured hardware and software. It is important, therefore, that you configure and test each device and software application before attempting to install MSCS. The same is true for determining problems. MSCS is designed to interact with the hardware and software...

Microsoft Cluster Server Basics 1
The cluster server comprises four categories of resources Nodes -The two whole computers that comprise the cluster - Individuality is superseded by cluster membership Individual resources -The applications, services, or components running on the cluster -The resources to which MSCS provides high availability Resource groups - Some resources require other resources to run successfully -These resources are grouped together to make maintenance easier - Logs data that is critical to recovery -...
MSCS Resource States
Initial state of resource. State is changed at request of the Cluster Service request is passed to the resource DLL entry point for execution. Transitional state of resource that is being brought online. Resource will either switch to online or revert to offline. State for a functioning resource. When a resource comes online, it is added to the monitors' list and LooksAlive IsAlive polling begins. Transitional state of resource being taken offline. Resource will either switch to offline or...
Cluster Tool Backup Resources
CLUSTOOL allows a quick recovery in case of a fatal failure of the cluster where a complete reinstall is the best solution. Without CLUSTOOL, complex cluster configurations i.e. configurations with a large number of virtual servers including their IP addresses and file shares take a long time to restore and are therefore expensive. Customers are often very reluctant to use this recovery approach due to extensive downtime and costs for administration. With a backup made with CLUSTOOL in place,...
CLUSTEREXE Command Line Program
Cluster.exe is a command line administration program, many of the commands can assist in assessing the state of cluster resources and performing cluster operations that may be prohibited because the GUI administrator will not run CLUSTER cluster name NODE node name Status CLUSTER cluster name RESOURCE resource name offline Cluster groups and resources that have been created using the command line program, batch file, can be restored easily in case of a catastrophic cluster failure CLUSTER...

Disk Signatures MSCS Resources and Clusdisk
The disk signature is used internally by MSCS as a resource parameter. For each shared disk its signature will be recorded in the registry key value. lt resourceID gt Parameters Signature -Where lt ResourceID gt is a random based number that uniquely identifies a resource The Cluster disk driver also records signatures of disks that have been locked defined as cluster resource in the value Services -where lt Sig gt is the disk signature of the device listed as lt n gt in Disk Admin The...
Network Problem Isolation
Ping nodes, cluster, virtual servers You can use ICSM to make sure all network resources are online. Use Ping on the interconnect network to confirm both nodes can be accessed. Use IPCONFIG from a Command Prompt to view all IP addresses currently used by this node. Confirm that the cluster name is registered on the client network. Confirm connection to all virtual servers. The MSCS cluster log records important events that take place during cluster service startup. Each manager component in...
Windows Advanced Server Cluster Tools
Many tools are available to use with Windows 2000 Advanced Server to perform exhaustive problem determination. CFGCMP Configuration Compare Monitoring Tools Event Log Replication When Clustering is installed on Windows 2000 servers, events logged in the event log of one node in the cluster are also replicated to the event log of the other nodes. Using the Cluster.exe command-line tool you can configure the behavior of this feature. To disable the replication of event logs for the entire cluster...
