Network Requirements
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.
Shared Disk Requirements
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 77 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, 3, 5,
10, 30 or 50.
