HP StorageWorks Fabric OS 6.3.3d Release Notes (5697-0493, May 2010 - includes all 6.3.0x versions)

The only mode of operation in releases prior to Fabric OS 6.2.x was the Idle implementation.
Fabric OS 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 Fabric OS 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 Fabric OS 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
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.

ports at idle [mode 0]. Can be
changed by the user.
• If pre-6.2.0d was installed in the
factory, all internal and external
ports remain at idle [mode 0],
unless they were manually
changed to arb(ff) [mode 1],
then they remain at arb(ff). Can
be changed by the user.
All ports default to idle [mode 0]
regardless of what FOS was previ-
ously installed, unless manually
