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 P9000 or XP Command View Advanced
Edition Software or XP Remote Web Console (shown). 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.
