Defining The Paths - HP XP20000/XP24000 Configuration Manual

IMPORTANT:
HP does not recommend:
Sharing of CHA (channel adapter) microprocessors
Multiple host groups sharing the same CHA port
NOTE: As illustrated in
microprocessor sharing with 8-port module pairs. With 16- and 32-port module pairs, alternating
ports are shared.

Defining the paths

Use P9000 or XP Command View Advanced Edition Software or XP Remote Web Console (shown)
to define paths between hosts and volumes (LUNs) in the disk array.
This process is also called "LUN mapping." In XP Remote Web Console, LUN mapping includes:
Configuring ports
Enabling LUN security on the ports
Creating host groups
Assigning Fibre Channel adapter WWNs to host groups
Mapping volumes (LDEVs) to host groups (by assigning LUNs)

For optimal performance when configuring any XP disk array with a Tru64 host,
