24 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX
Configuring the Fibre Channel ports
Configure the disk array Fibre Channel ports by using Remote Web
Console (shown), Command View, or Command View XP AE. Select the
settings for each port based on your storage area network topology. Use
switch zoning if you connect different types of hosts to the array through
the same switch.
Fibre Address
In fabric environments, the port addresses are assigned automatically. In
arbitrated loop environments, set the port addresses by selecting a unique
arbitrated loop physical address (AL-PA) or loop ID for each port.
