Setting Up and Zoning the Fabric
NOTE: This section does not apply for a direct connection or when deploying HP Virtual Connect
Direct-Attach Fibre Channel storage for HP 3PAR storage systems, where the HP 3PAR StoreServ
Storage ports are cabled directly to the uplink ports on the HP Virtual Connect FlexFabric 10
Gb/24-port Module for c-Class BladeSystem. Zoning is automatically configured based on the
Virtual Connect SAN Fabric and server profile definitions.
For more information about HP Virtual Connect, HP Virtual Connect interconnect modules, and the
HP Virtual Connect Direct-Attach Fibre Channel feature, see HP Virtual Connect documentation.

Fabric zoning controls which FC end-devices have access to each other on the fabric. Zoning also
isolates the host and HP 3PAR StoreServ Storage ports from Registered State Change Notifications
(RSCNs) that are irrelevant to these ports.
You can set up fabric zoning by associating the device World Wide Names (WWNs) or the switch
ports with specified zones in the fabric. Although you can use either the WWN method or the port
zoning method with the HP 3PAR StoreServ Storage, the WWN zoning method is recommended
because the zone survives the changes of switch ports when cables are moved around on a fabric.
Required
Employ fabric zoning, using the methods provided by the switch vendor, to create relationships
between host HBA ports and storage server ports before connecting the host HBA ports or HP 3PAR
StoreServ Storage ports to the fabric(s).
FC 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 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 Also, see the 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.
