The network requirements for clustering are:

•  A unique NetBIOS cluster name

•  Five unique, static IP addresses:

•  two are for the network adapters on the internal network

•  two are for the network adapters on the external network

•  one is for the cluster itself

•  A domain user account for Cluster Service (all nodes must be part of the same

domain.)

•  Two network adapters for each node—one for connection to the external network and

the other for the node-to-node internal cluster network. If you do not use two network
adapters for each node, your configuration is unsupported. HCL certification requires
a separate private network adapter.

Disks can be shared by the nodes. The requirements for sharing disks are as follows:

•  Physically attach all shared disks, including the quorum disk, to the shared bus.

•  Make sure that all disks attached to the shared bus are seen from all nodes. You can

check this at the setup level in <Ctrl> <M> (the BIOS configuration utility.) See page
69 for installation information.

•  Assign unique SCSI identification numbers to the SCSI devices and terminate the

devices properly. Refer to the storage enclosure manual about installing and
terminating SCSI devices.

•  Configure all shared disks as basic (not dynamic.)

•  Format all partitions on the disks as NTFS.

It is best to use fault-tolerant RAID configurations for all disks. This includes RAID
levels 1, 5, 10, 30 or 50.
