Configure FC switches

Defining the paths
Installation
Open VMS supports Fibre Channel only in a switch topology. Refer to the
switch documentation to set up the switch. The disk array may support a
large number of LUs. Open VMS supports 32,768 LUs per port.
Use Command View (shown) or LUN Configuration Manager to create
paths (LUNs) between hosts and volumes in the disk array. This process is
also called "LUN mapping." LUN mapping includes:
• Configuring ports
• Setting LUN security
• Creating host groups
• Assigning host bus adapter WWNs to host groups.
• Mapping volumes to host groups (by assigning LUNs).
See the Command View or LUN Configuration Manager guide for more
information. Note the LUNS and their ports, WWNs, nicknames, and
LDEVs for later use in verifying host and device configuration.
Path configuration for Open VMS requires the following steps:
1. If you will be using RAID Manager, define a single "command device"
LUN per XP array and present it to the Open VMS hosts across all
connected paths.
