Cluster Installation
Installation Overview During installation, some nodes are shut down, and other nodes are rebooted. This
is necessary to ensure uncorrupted data on disks attached to the shared storage bus. Data
corruption can occur when multiple nodes try to write simultaneously to the same disk, if
that disk is not yet protected by the cluster software.
The table below shows which nodes and storage devices should be powered on during
each step.

Before installing the Cluster Service software you must follow the steps below:
• Install Windows 2000 Advanced Server or Windows 2000 Datacenter Server on each
node
• Setup networks
• Setup disks
Note:
These steps must be completed on every cluster node before proceeding with the
installation of Cluster Service on the first node.
To configure the Cluster Service on a Windows 2000-based server, you must be able to
log on as administrator or have administrative permissions on each node. Each node must
be a member server, or be domain controllers inside the same domain. A mix of domain
controllers and member servers in a cluster is not acceptable.
