Network requirements
■
A unique NetBIOS cluster name
■
Five unique, static IP addresses: two for the network adapters
on the private network, two for the network adapters on the
public network, and one for the cluster itself.
■
A domain user account for Cluster service (all nodes must be
members of the same domain)
■
Each node should have at least two network adapters—one
for connection to the public network and the other for the
node-to-node private cluster network. If only one network
adapter is used for both connections, the configuration is
unsupported. A separate private network adapter is required
for HCL certification.
Shared disk requirements
Note:
Do not let more than one node access the shared storage
devices at the same time until Cluster service is installed on at least
one node and that node is online. This can be accomplished through
selective storage presentation, SAN switch zoning or having only one
node online at all times.
■
All software components listed in the SAN connection tool
must be installed and the fibre cables attached to the HBA(s)
before the cluster installation is started.
■
All shared disks, including the quorum disk, must be
accessible from all nodes.
■
All shared disks must be configured as basic (not dynamic).
■
All partitions on the disks must be formatted as NTFS.
Cluster installation overview
During the installation process, nodes will be shut down and
rebooted. These steps are necessary to guarantee that the data on
disks that are attached to the shared storage bus is not lost or
corrupted. This can happen when multiple nodes try to
simultaneously write to the same disk that is not yet protected by
the cluster software.
