Understanding Your Failover Cluster
45
Replacing a Failed Disk
If a disk in a Failover Cluster has failed, you can assign a different disk. To
replace the failed disk:
1 Right-click on the resource and click Properties.
2 In the General tab, click Repair, and select a new disk that you want to
use. The new disk that you assign must be one that can be clustered.
NOTE:
The Repair option does not recover data. You can restore data to the disk
before using the Repair option.
File Share Resource Type
If you want to use your cluster solution as a high-availability file server, select
one of the following types of file share for your resource:
• Basic file share — Publishes a file folder to the network under a single
name.
• Share subdirectories — Publishes several network names-one for each file
folder and all of its immediate subfolders. This method is an efficient way
to create large numbers of related file shares on a file server.
• DFS root — Creates a resource that manages a stand-alone DFS root.
Fault-tolerant DFS roots cannot be managed by this resource. A DFS root
file share resource has required dependencies on a network name and an IP
address. The network name can be either the cluster name or any other
network name for a virtual server.
Configuring Active and Passive Cluster Nodes
Active nodes process application requests and provide client services. Passive
nodes are backup nodes that ensure that client applications and services are
available if a hardware or software failure occurs. Cluster configurations may
include both active and passive nodes.
NOTE:
Passive nodes must be configured with appropriate processing power and
storage capacity to support the resources that are running on the active nodes.
Your cluster solution supports variations of active/active and active/passive
configurations.
Cluster solutions running the Windows Server 2008 operating system can
support up to sixteen nodes in multiple configurations.
