How to find the location of the Quorum disk?

Hi
Can anyone tell me how to find the location fo the Quorum disk, which
is not located in the server but in any one of the nodes? I have
checked the registry of the cluster server, it tells me the path of
the quorum disk but not the node name or the machine ID. I assume it
has to do somethign with the IP Address of the node, but I am not
being able to solve it. Please help.
Thanks
M

Hi
Look at the command line tool cluster.exe:
cluster /quorum

Thanks Mike...but I was not looking for some utility tools . What
i am looking for is conceptual knowledge. I want to know where, the
location of the quorum disk is stored, in the system. Can u help me
with some conceptual idea about the location of quorum disk? :?:
Thanks and regards

To know the node name, you will need to know which node is owning the quorum resource at that time. Note at any time, the resource can be owned by only one node as Windows MSCS is based on shared nothing
model. One of the ways to own the owner of the quorum resource is to open the Cluster Administrator and look at the owner of the quorum resource.

|||Here is some coneptual information (from Windows 2003 Help) that you may find helpful for the quorum resource
Quorum resource
In every cluster, a single resource is designated as the quorum resource. This resource maintains the configuration data necessary for recovery of the cluster. This data, in the form of recovery logs, contains
details of all of the changes that have been applied to the cluster database. This provides node-independent storage for cluster configuration and state data.
Quorum resource and the cluster database
The cluster database is an integral part of the formation of a server cluster. When a node joins or forms a cluster, the Cluster service must update the node's private copy of the cluster database. When a node
joins an existing cluster, the Cluster service can retrieve the data from the other active nodes. However, when a node forms a cluster, no other node is available. The Cluster service uses the quorum resource's
recovery logs to update the node's cluster database. To ensure cluster unity, Windows Server 2003, Enterprise Edition and Windows Server 2003, Datacenter Edition use the quorum resource to ensure that only
one set of active, communicating nodes is allowed to operate as a cluster. A node can form a cluster only if it can gain control of the quorum resource. A node can join a cluster or remain in an existing cluster only if
it can communicate with the node that controls the quorum resource.
For more information on the cluster database, see Cluster database.
For more information on cluster resources, see Server cluster resources.
Scenarios
To illustrate the importance of the quorum resource, consider these situations in a simple two-node cluster:
Node 1 fails. Node 2 continues operating, writing changes to the cluster database. But before node 1 can be restarted, node 2 fails. When node 1 becomes active, it must update its private copy of the cluster
database with the changes made by node 2. The Cluster service uses the quorum resource's recovery logs to perform the update.
The networks providing communication between nodes 1 and 2 fail. Each node assumes the other node has failed and attempts to continue operating as the cluster. If both could succeed, the result would be two
separate clusters using the same cluster name and competing for the same resources. Windows Server 2003, Enterprise Edition and Windows Server 2003, Datacenter Edition use quorum resource ownership to
prevent this problem and maintain cluster unity. In this scenario, the node that gains control of the quorum resource is allowed to form a cluster, and the other fails over its resources and becomes inactive.
The quorum resource can be any resource with the following attributes:
The resource must enable a single node to gain physical control of it and defend its control.
The resource must provide physical storage that can be accessed by any node in the cluster.
The resource must use the NTFS file system.
Types of quorum resources
There are two resources that come with the operating system that can act as a quorum resource for multinode clusters. They are:
The Physical Disk resource
The Majority Node Set resource
For single-node clusters, the Local Quorum resource acts as a quorum resource. However, other developers can create their own quorum resource types for any resources that meet the arbitration and storage
requirements. For more information, see the Microsoft Software Development Kit (SDK).
