With Fabric OS 6.1.2x and 6.2.0d and later, the default reverted to the IDLE implementation. The new portCfgFillWord command was also implemented beginning with these versions, and enables the user to configure the ARB(FF) 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 Fabric OS 6.1.2x or later does not automatically change the mode (with the exception of 6.2.0a and 6.2.0b, as noted above). In current configurations, the mode must be changed manually. This does not affect 1-Gb, 2-Gb, or 4-Gb devices. The mode 1 setting has no effect on these devices; it affects only devices that negotiate or are fixed at 8-Gb speeds. ◦ Changing the mode after Fabric OS 6.1.2x has been installed If you change the mode after installing Fabric OS 6.1.2x or later, with the exception as noted above for 6.2.0a and 6.2.0b, the portCfgFillWord command changes the configuration parameter in accordance with the selected mode, and automatically disables/enables 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, 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 is connected to a 2-Gb or 4-Gb SFP, and that SFP is replaced with an 8-Gb SFP, then the current behavior of the mode is activated. ◦ The following table provides a portcfgfillword summary: Fabric OS version All 8-Gb switches except 8-Gb SAN Switch for HP BladeSystem c-Class 8-Gb SAN Switch for HP BladeSystem c-Class Any Fabric OS earlier All ports set to IDLE. than 6.1.2 No ARB(FF) capability.

With Fabric OS 6.1.2x and 6.2.0d and later, the default reverted to the IDLE
implementation. The new
portCfgFillWord
command was also implemented beginning
with these versions, and enables the user to configure the ARB(FF) 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 Fabric OS 6.1.2x or later does not automatically change the mode (with the
exception of 6.2.0a and 6.2.0b, as noted above). In current configurations, the mode
must be changed manually. This does not affect 1-Gb, 2-Gb, or 4-Gb devices. The mode
1 setting has no effect on these devices; it affects only devices that negotiate or are fixed
at 8-Gb speeds.
◦
Changing the mode after Fabric OS 6.1.2x has been installed
If you change the mode after installing Fabric OS 6.1.2x or later, with the exception as
noted above for 6.2.0a and 6.2.0b, the
portCfgFillWord
command changes the
configuration parameter in accordance with the selected mode, and automatically
disables/enables 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, 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 is connected to a 2-Gb or 4-Gb SFP, and thatSFP is replaced with an 8-Gb
SFP, then the current behavior of the mode is activated.
