HP StorageWorks 8/8 - SAN Switch Release Note page 28

slotnumber: For bladed systems only, specifies the slot number of the port to configure, fol-
lowed by a slash (/).
portnumber: Specifies the number of the port to configure, relative to its slot for bladed sys-
tems. Use the switchShow command to list valid ports.
mode: Specifies the fill word for portnumber. This operand is required. Valid values are one
of the following:
0 IDLE in Link Init and IDLE as fill word (default)
1 ARB(ff) in Link Init and ARB(ff) as fill word
Example: To set the fill word of a port to ARBFF-ARBFF:
switch:admin> portcfgfillword 2/3, 1
For more information, see the portCfgShow command in the Fabric OS Command Reference
Manual.
Behavior
Default mode: The only mode of operation in releases earlier than Fabric OS 6.1.2 was the
IDLE implementation. FOS v6.2.0a and v6.2.0b defaulted to ARB/ARB for 8-Gb devices. With
the introduction of FOS v6.2.0d, the new command defaulted to mode 0 (Idle) and enabled
the user to configure the ARB configuration.
Existing Product: This change has no effect on current product configurations in the field. The
mode is currently 0, and during a firmware upgrade the mode remains 0 and no devices are
impacted. If a new device is added to the configuration that requires the ARB sequence, those
ports can be configured at that time. Loading 6.2.0d or later does not automatically change
the mode. In current configurations the mode has to be changed manually. This change does
not affect 1G-b/2-Gb /4-Gb devices. Settings of 0 or 1 have no affect on these devices. It
only affects devices that negotiate or are fixed to 8-Gb speeds.
Changing the mode after FOS v6.2.0d is installed: If you change the mode after installing
Fabric OS 6.2.0d or later 6.2.0x release, the portCfgFillWord command changes the
configuration parameter in accordance with the selected mode, and automatically disables/en-
ables the port for which the command was invoked. Subsequent Link Initializations will default
to the new mode setting.
Other scenarios: The portcfgfillword command has no effect on 1-Gb / 2-Gb /4-Gb
devices but the mode is persistent. If a device attempts to negotiate or is fixed to 8-Gb, the
configured mode will take effect. The persistent configuration is on a port-by-port basis (that
is, if an 8-Gb device was connected to a 2-Gb or 4-Gb optic and that optic was replaced with
an 8-Gb optic, the current behavior of the mode is activated.)
Table 6 summarizes the portcfgfillword command.
