Configuring Virtual Channel Settings; Configuring System Services; Configuring Arbitrated Loop Parameters - HP StorageWorks 2/64 - Core Switch Administrator's Manual

Configuring virtual channel settings

You can configure the parameters for eight virtual channels to enable fine-tuning for a specific
application. You cannot modify the first two virtual channels, which are reserved for switch internal
functions.
CAUTION: The default virtual channel settings have already been optimized for switch performance.
Changing the default values can improve switch performance but can also degrade performance. Do not
change these settings without fully understanding the effects of the changes.
VC Priority specifies the class of frame traffic given priority for a virtual channel.

Check this box to specify that fabric address notification (FAN) frames are sent to
public loop devices to notify them of their node ID and address.
Following the completion of loop initialization, a remote state change notification
(RSCN) is issued when FL_Ports detect the presence of new devices or the absence of
pre-existing devices. Check this box to issue an RSCN upon completion of loop
initialization, regardless of the presence or absence of new or pre-existing devices.
Check this box to disable 0x00 as an arbitrated loop physical address (AL_PA) value.
