HP 3PAR Coexistence

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 hostHBA ports and storage server ports before connecting the host HBA ports or HP 3PAR StoreServ Storage ports to the fabric(s).

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 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. This document is available on the HP BSC website:

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 HBA port and HP 3PAR StoreServ Storage port to the fabric(s), verify the switch and zone configurations using the HP 3PAR OS CLI showhost command, to ensure that each initiator is zoned with the correct target(s).

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 HP BSC website:

Configuration Guidelines for Fabric Vendors

Use the following fabric vendor guidelines before configuring ports on fabric(s) to which the HP 3PAR StoreServ Storage connects.

•Brocade switch ports that connect to a host HBA port or to an HP 3PAR StoreServ Storage port should be set to their default mode. On Brocade 3xxx switches running Brocade firmware
