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 adapter using the FCA manufacturer's instructions. HP supplies driver, firmware, and BIOS downloads for commonly available FCAs. These downloads contain FCA settings that are tested and approved by HP. To obtain a download, log onto the HP website at www.hp.com and search for the model name or number of your FCA. Download the file, and follow the installation instructions in the "readme" or documentation file supplied with each download. Contact your HP representative for current information on compatible FCAs. Fabric zoning and LUN security By using appropriate zoning and LUN security, you can connect various servers with various operating systems to the same switch and fabric with the following restrictions: • Storage port zones can overlap if more than one operating system needs to share an array port. • Heterogeneous operating systems can share an array port if you set the appropriate host group and mode. All others must connect to a dedicated array port. • Use LUN Manager for LUN isolation when multiple hosts connect through a shared array port. LUN Manager provides LUN security by allowing you to restrict which LUNs each host can access. • QLogic and Emulex FCAs must be in separate zones (a QLogic zone and an Emulex zone) whether the FCAs are in the same or separate servers. • If booting over the SAN, within a server, the booting FCAs must be from the same vendor. Additional data storage FCAs can be from a different vendor.

host to the disk array.
Loading the operating system and software

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 adapter using the FCA manufacturer's instructions.
HP supplies driver, firmware, and BIOS downloads for commonly available FCAs. These downloads

and search for the model name or number of your FCA. Download the
file, and follow the installation instructions in the “readme” or documentation file supplied with
each download.
Contact your HP representative for current information on compatible FCAs.
Fabric zoning and LUN security
By using appropriate zoning and LUN security, you can connect various servers with various
operating systems to the same switch and fabric with the following restrictions:
•
Storage port zones can overlap if more than one operating system needs to share an array
port.
•
Heterogeneous operating systems can share an array port if you set the appropriate host
group and mode. All others must connect to a dedicated array port.
•
Use LUN Manager for LUN isolation when multiple hosts connect through a shared array port.
LUN Manager provides LUN security by allowing you to restrict which LUNs each host can
access.
•
QLogic and Emulex FCAs must be in separate zones (a QLogic zone and an Emulex zone)
whether the FCAs are in the same or separate servers.
•
If booting over the SAN, within a server, the booting FCAs must be from the same vendor.
Additional data storage FCAs can be from a different vendor.

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.
