HP 3PAR HP-UX Implementation Guide

Required
Employ fabric zoning, using the methods provided by the switch vendor, to create relationships
between host server HBA ports and HP 3PAR StoreServ Storage ports before connecting to the
fabrics.
Fibre Channel switch vendors support the zoning of the fabric end-devices in different zoning
configurations. There are advantages and disadvantages with each zoning configuration. Choose
a zoning configuration based on your needs.
The HP 3PAR StoreServ Storage arrays support the following zoning configurations:
• One initiator to one target per zone
• One initiator to multiple targets per zone (zoning by HBA). This zoning configuration is
recommended for the HP 3PAR StoreServ Storage. Zoning by HBA is required for coexistence
with other HP Storage arrays.
NOTE: For high availability/clustered environments that require multiple initiators to access
the same set of target ports, HP recommends that separate zones be created for each initiator
with the same set of target ports.
NOTE: The storage targets in the zone can be from the same HP 3PAR StoreServ Storage,
multiple HP 3PAR StoreServ Storages , or a mixture of HP 3PAR and other HP storage systems.
For more information about using one initiator to multiple targets per zone, see Zoning by HBA in
the Best Practices chapter of the HP SAN Design Reference Guide, available on the following
website:
HP SAN Design Reference Guide
If you use an unsupported zoning configuration and an issue occurs, HP may require that you
implement one of the supported zoning configurations as part of the troubleshooting or corrective
action.
After configuring zoning and connecting each host server HBA port and HP 3PAR StoreServ Storage
port to the fabrics, verify the switch and zone configurations using the HP 3PAR OS CLI showhost
command, to ensure that each initiator is zoned with the correct targets.
HP 3PAR Coexistence
The HP 3PAR StoreServ Storage array can coexist with other HP array families.
For supported HP arrays combinations and rules, see the HP SAN Design Reference Guide, available
on the following website:

Configuration Guidelines for Fabric Vendors
Use the following fabric vendor guidelines before configuring ports on fabric to which the HP 3PAR
StoreServ Storage connects.
• Brocade switch ports that connect to a host server HBA port or to an HP 3PAR StoreServ
Storage port should be set to their default mode. On Brocade 3xxx switches running Brocade
firmware 3.0.2 or later, verify that each switch port is in the correct mode using the Brocade
telnet interface and the portcfgshow command, as follows:
brocade2_1:admin> portcfgshow
Ports 0 1 2 3 4 5 6 7
