Conﬁguring system ﬁles

Conﬁgure the Tru64 system to recognize the HBA as explained in the Tru64 Installation Gu ide or New

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

explained in the Installation Guide). This can also sometimes be done by ed iting the system kernel

conﬁguration ﬁle as explained below.

1. Use the doconﬁg-cconﬁg_ﬁle command to reconﬁgure the kernel, where conﬁg_ﬁle is usually

the system n

ame.

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

reboot causes the host to recognize the new HBA. No rebuilding or reconﬁgu ration is required.

Clustering and fabric zoning

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

Clustering is the organization of multiple servers into groups. Within a cluster, ea ch 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. Alwa ys conﬁgure an array so that a host

group is presented to only 1 cluster.

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

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

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