Understanding Your Failover Cluster
41
Forming a New Cluster
Failover Clustering maintains a current copy of the cluster database on all
active nodes. If a node cannot join a cluster, the node attempts to gain control
of the witness disk resource in Node and Disk Majority model and forms a
cluster. The node uses the recovery logs in the quorum resource to update its
cluster database.
Joining an Existing Cluster
A node can join a cluster if it can communicate with another active node in
the cluster. When a node joins a cluster, the node is updated with the latest
copy of the cluster database. Failover Clustering validates the node's name,
verifies version compatibility, and the node joins the cluster.
Cluster Resources
A cluster resource is any physical or logical component that can be:
• Brought online and taken offline
• Managed in a cluster
• Hosted by one managed system at a time
Setting Resource Properties
Failover Clustering allows you to set the properties for any resource that is a
part of the cluster.
To change or modify resource properties:
1 Right-click the resource you want to modify and click on Properties. The
resource properties are listed under four tabs:
• General- Allows you to rename the resource or use the Repair option
to stop using a failed disk and assign a different disk.
• Dependencies- Failover Clustering uses the resource dependencies list
when bringing resources online and offline.
For example, if a group with a physical disk and a file share is brought
online together, the physical disk containing the file share must be
brought online before the file share. Under the Dependencies tab, you
can specify the resources that must be brought online before your
resource can come online. You can add multiple dependencies using
