Windows server 2003 2 node cluster

Why is that? How can i correct? Saturday, March 19, AM. Tuesday, March 22, AM. Gunner Thanks for the reply I've done more general research myself and i post my results In the case A: - no heartbeat possible because heartbeat configured only on private NIC, and NIC dead on one node - Both nodes still alive and functional We are in a "Split Brain" situation, where each node doens't know if it has to be the cluster owner.

The behaviour of the entire cluster is explained very good in a past article by Jason Nash which i quote "Whenever the cluster cannot determine who owns the quorum, challenge - defense is initiated. If the nodes of a cluster lose network communication with each other for example, if there is no communication over the private or public network , the Cluster service by using Clusdisk. The following procedure describes what occurs if the nodes in a cluster lose network connectivity and there is no available network for heartbeat communications: 1.

The node that currently owns the quorum disk is called the "defender. All other nodes nodes that do not own the quorum disk become the "challengers. When the challenger detects the loss of heartbeat communications, it immediately issues a bus-wide scsi reset command.

Ten seconds after the scsi reset command is issued, the challenger tries to reserve the quorum disk. If the defender node is online and functioning, it will have already reserved the quorum disk as it typically does every three seconds. The challenger detects that it cannot reserve the quorum, and then shuts down its Cluster service. If the defender is not functioning properly, the challenger can successfully reserve the quorum disk.

August 8, at am But our according to our Windows admin, in Windows , the cluster installation is completely changed and so it's NOT possible to perform upgrade of a 2 node clustered Windows x64 to Windows x64 But, I'm NOT sure whether any body did this kind of upgrade and what Microsoft suggests and our Windows admin still looking for the options to achieve this upgrade If you find any information, please share in this thread.

August 9, at pm I did find the below but NOT the complete documentation If you want to upgrade the operating system on the cluster nodes to Windows Server , you will face some challenges. This leaves you two choices: 1. August 10, at am August 10, at pm
