Setting the system option modes
The HP service representative sets the system option mode(s) based on the operating system and
software configuration of the host. Notify your HP representative if you install storage agnostic
software (such as backup or cluster software) that might require specific settings.
Installing and configuring the host
This section explains how to install and configure Fibre Channel adapters (FCAs) or Converged
Network adapters (CNA) that connect the host to the disk array.
Installing and configuring the FCAs, CNAs
Install and configure the Fibre Channel or Converged Network adapters using the manufacturer's
instructions.
Loading the operating system and software
Follow the manufacturer's instructions to load the operating system and software onto the host.
Load all OS patches and configuration utilities supported by HP and the FCA or CNA manufacturer.
Clustering and fabric zoning
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.
Figure 8 Multi-cluster environment (Linux)
Within the SAN, the clusters can be homogeneous (all the same operating system) or heterogeneous
(mixed operating systems). How you configure LUN security and fabric zoning depends on the
operating system mix and the SAN configuration.
