HP 3PAR X9000 File Serving Software (IBRIX) Implementation Guide (QL226-96987, June 2013)

Required
Employ fabric zoning, using the methods provided by the switch vendor, to create relationships
between host server HBA ports and storage server ports before connecting the host server 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
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 website:
http://www.hp.com/go/3par/
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 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).
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 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

The following fill-word modes are supported on a Brocade 8 G/s switch running FOS firmware
6.3.1a and later:
admin>portcfgfillword
Usage: portCfgFillWord PortNumber Mode [Passive]
Mode: 0/-idle-idle - IDLE in Link Init, IDLE as fill word (default)
1/-arbff-arbff - ARBFF in Link Init, ARBFF as fill word
2/-idle-arbff - IDLE in Link Init, ARBFF as fill word (SW)
3/-aa-then-ia - If ARBFF/ARBFF failed, then do IDLE/ARBFF
HP recommends that you set the fill word to mode 3 (aa-then-ia), which is the preferred
mode using the portcfgfillword command. If the fill word is not correctly set, er_bad_os
counters (invalid ordered set) will increase when you use the portstatsshow command
while connected to 8 G HBA ports, as they need the ARBFF-ARBFF fill word. Mode 3 will
