IMPORTANT: For optimal performance when configuring any XP disk array with a Tru64 host, HP does not recommend: • Sharing of CHA (channel adapter) microprocessors • Multiple host groups sharing the same CHA port NOTE: As illustrated in "Microprocessor port sharing (OpenVMS)" (page 58), there is no microprocessor sharing with 8-port module pairs. With 16- and 32-port module pairs, alternating ports are shared.

IMPORTANT:
For optimal performance when configuring any XP disk array with a Tru64 host,
HP does not recommend:
•
Sharing of CHA (channel adapter) microprocessors
•
Multiple host groups sharing the same CHA port
NOTE:
As illustrated in
“Microprocessor port sharing (OpenVMS)” (page 58)
, there is no
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)
