Configuring system files

Configure the Tru64 system to recognize the FCA as explained in the Tru64 Installation Guide or

New Hardware Delivery (NHD) kit. This consists of booting genvmunix and executing doconfig (as

explained in the Installation Guide). This can also be done by editing the system kernel configuration

file as explained below.

Use the doconfig -c config_file command to reconfigure the kernel, where

config_file is usually the system name.

When you add a new FCA after an FCA of the same type has already been installed, a simple

reboot causes the host to recognize the new FCA. No rebuilding or reconfiguration is required.

If you plan to use clustering, install and configure the clustering software on the servers.

Clustering is the organization of multiple servers into groups. Within a cluster, each server is a node.

Multiple clusters compose a multi-cluster environment. The following example shows a multi-cluster

environment with three clusters, each containing two nodes. The nodes share access to the disk array.

In this example, the array is configured so that Host Group 00 is presented only to Cluster 1, Host

Group 01 only to Cluster 2, and Host Group 02 only to Cluster 3. Always configure an array so that

a host group is presented to only 1 cluster.

Figure 2 Multi-cluster environment

Within the Storage Area Network (SAN), the clusters may be homogeneous (all the same operating

system) or they may be heterogeneous (mixed operating systems). How you configure LUN security

and fabric zoning depends on the operating system mix and the SAN configuration.

You can connect multiple clusters of various operating systems to the same switch and fabric using

appropriate zoning and LUN security as follows:

•

Storage port zones may overlap if more than one operating system needs to share an array port.
