portCfgFillWord command The portCfgFillWord command configures the fill word for a single 8-Gb FC port. • Syntax: portcfgfillword [slotnumber/]portnumber, mode • Description: Use this command to configure the fill word for an 8-Gb FC port. (It does not apply to a non-8-Gb FC port.) This command disables and re-enables the port; the port comes online with the new fill-word setting. The configuration is stored in nonvolatile memory and is persistent across switch reboots and power cycles. • Notes: This configuration cannot be set on VE_Ports or VEX_Ports. Use the portCfgShow command to display user-configured fill-word settings. The execution of this command is subject to any Administrative Domain or VF restrictions. • Operands: This command has the following operands: • slotnumber-For blade systems only, specifies the slot number of the port to be configured, followed by a slash (/). • portnumber-Specifies the number of the port to be configured, relative to its slot for blade systems. Use the switchShow command to display a list of valid ports. • mode-Specifies the fill word for portnumber. This operand is required. Valid values are as follows: • 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 See also the portCfgShow command in the Fabric OS Command Reference Manual. • Behavior: • Default mode The only mode of operation in releases prior to FOS 6.2.x was the Idle implementation. FOS 6.2.0a and 6.2.0b defaulted to ARB/ARB for 8-Gb devices. With 6.2.0d, the default reverted to the Idle implementation. The new portCfgFillWord command enables the user to configure the ARB configuration. • Existing product For products in the field, this change has no effect on current configurations. The mode is currently 0, and during a firmware upgrade, the mode will remain 0 and no devices will be impacted. If a new device is added to the configuration, and it requires the ARB sequence, the ports can be configured at that time. Loading FOS 6.2.x does not automatically change the mode. In current configurations, the mode must be changed manually. This does not affect 1-Gb, 2-Gb, or 4-Gb devices. Any settings of 0 or 1 have no effect on these devices; they affect only devices that negotiate or are fixed at 8-Gb speeds. If you change the mode after installing FOS 6.2.0d or later, the portCfgFillWord command changes the configuration parameter and automatically disables/enables the port for which the command was invoked. Subsequent link initializations will use ARB(FF). • Other scenarios The portCfgFillWord command has no effect on 1-Gb, 2-Gb, or 4-Gb devices, but the mode is persistent. If a device attempts to negotiate or is fixed at 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 HP StorageWorks FOS 6.3.0b Release Notes 35

portCfgFillWord
command
The
portCfgFillWord
command configures the fill word for a single 8-Gb FC port.
•
Syntax:
portcfgfillword [slotnumber/]portnumber, mode
•
Description:
Use this command to configure the fill word for an 8-Gb FC port. (It does not apply
to a non-8-Gb FC port.) This command disables and re-enables the port; the port comes online
with the new fill-word setting. The configuration is stored in nonvolatile memory and is persistent
across switch reboots and power cycles.
•
Notes:
This configuration cannot be set on VE_Ports or VEX_Ports. Use the
portCfgShow
command
to display user-configured fill-word settings. The execution of this command is subject to any Ad-
ministrative Domain or VF restrictions.
•
Operands:
This command has the following operands:
•
slotnumber
—
For blade systems only, specifies the slot number of the port to be configured,
followed by a slash (/).
•
portnumber
—
Specifies the number of the port to be configured, relative to its slot for blade
systems. Use the
switchShow
command to display a list of valid ports.
•
mode
—
Specifies the fill word for
portnumber
. This operand is required. Valid values are as
follows:
•
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
See also the
portCfgShow
command in the
Fabric OS Command Reference Manual
.
•
Behavior:
•
Default mode
The only mode of operation in releases prior to FOS 6.2.x was the Idle implementation. FOS
6.2.0a and 6.2.0b defaulted to ARB/ARB for 8-Gb devices. With 6.2.0d, the default reverted
to the Idle implementation. The new
portCfgFillWord
command enables the user to configure
the ARB configuration.
•
Existing product
For products in the field, this change has no effect on current configurations. The mode is cur-
rently 0, and during a firmware upgrade, the mode will remain 0 and no devices will be im-
pacted. If a new device is added to the configuration, and it requires the ARB sequence, the
ports can be configured at that time.
Loading FOS 6.2.x does not automatically change the mode. In current configurations, the
mode must be changed manually. This does not affect 1-Gb, 2-Gb, or 4-Gb devices. Any settings
of 0 or 1 have no effect on these devices; they affect only devices that negotiate or are fixed
at 8-Gb speeds.
If you change the mode after installing FOS 6.2.0d or later, the
portCfgFillWord
command
changes the configuration parameter and automatically disables/enables the port for which
the command was invoked. Subsequent link initializations will use ARB(FF).
•
Other scenarios
The
portCfgFillWord
command has no effect on 1-Gb, 2-Gb, or 4-Gb devices, but the
mode is persistent. If a device attempts to negotiate or is fixed at 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
