HP 3PAR Citrix Implementation Guide

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.
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 need to be from the same HP 3PAR StoreServ Storage
or multiple HP 3PAR StoreServ Storage systems.
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).
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
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
-----------------+--+--+--+--+----+--+--+--
Speed AN AN AN AN AN AN AN AN
Trunk Port ON ON ON ON ON ON ON ON
Locked L_Port .. .. .. .. .. .. .. ..
Locked G_Port .. .. .. .. .. .. .. ..
Disabled E_Port .. .. .. .. .. .. .. ..
where AN:AutoNegotiate, ..:OFF, ??:INVALID.
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
also work correctly for lower-speed HBAs, such as 4 Gb/2 Gb HBAs. For more information,
see the Fabric OS command Reference Manual supporting FOS 6.3.1a and the FOS release
notes.
