CAUTION: Changing host group modes for ports where servers are already installed and
configured is disruptive and requires the server to be rebooted.
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.
Configuring the Fibre Channel ports
Configure the disk array Fibre Channel ports by using Command View Advanced Edition or Remote
Web Console. Select the settings for each port based on your SAN topology. Use switch zoning
if you connect different types of hosts to the array through the same switch.
Installing and configuring the host
This section explains how to install and configure Fibre Channel adapters (FCAs) that connect the
host to the disk array.
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 manufacturer.
Installing and configuring the FCAs
Install and configure the Fibre Channel adapters using the FCA manufacturer's instructions.
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.
