The following fill-word modes are supported on a Brocade 8 Gb/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 Gb 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 additional
information, see the Brocade Fabric OS Command Reference Manual available at:
www.brocade.com
In addition, some HP switches, such as the HP SN8000B 8-slot SAN backbone director switch,
the HP SN8000B 4-slot SAN director switch, the HP SN6000B 16 Gb FC switch, or the HP
SN3000B 16 Gb FC switch automatically select the proper fill-word mode 3 as the default
setting.
• McDATA switch or director ports should be in their default modes as G or GX-port (depending
on the switch model), with their speed setting permitting them to autonegotiate.
• Cisco switch ports that connect to HP 3PAR StoreServ Storage ports or host HBA ports should
be set to AdminMode = FX and AdminSpeed = auto port, with the speed set to auto negotiate.
• QLogic switch ports should be set to port type GL-port and port speed auto-detect. QLogic
switch ports that connect to the HP 3PAR StoreServ Storage should be set to I/O Stream Guard
disable or auto, but never enable.
Target Port Limits and Specifications
To avoid overwhelming a target port and ensure continuous I/O operations, observe the following
limitations on a target port:
• Maximum of 64 host server ports per HP 3PAR StoreServ Storage port, with a maximum total
of 1,024 host server ports per HP 3PAR StoreServ Storage.
• Maximum I/O queue depth on each HP 3PAR StoreServ Storage HBA model, as follows:
QLogic 2G: 497◦
◦ LSI 2G: 510
◦ Emulex 4G: 959
◦ HP 3PAR HBA 4G: 1638
◦ HP 3PAR HBA 8G: 3276 (HP 3PAR StoreServ 10000 and HP 3PAR StoreServ 7000
systems only)
