Configure Command Virtual Channel Fields - HP StorageWorks 2/64 - Core Switch Command Reference Manual

Virtual channel settings
The switch enables fine-tuning for a specific application by configuring the parameters for eight virtual
channels. The first two virtual channels are reserved for switch internal functions and are not available for
modification.
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.
Table 6 lists the virtual channel fields and their settings.

VC Priority specifies the class of frame traffic given priority for a virtual channel.
Zoning operation parameters
The zoning operation parameter field is as follows:
Disable NodeName
Zone Checking
126 Fabric OS commands
The buffer-to-buffer (BB) credit represents the number of buffers
available to attached devices for frame receipt. The range of allowed
values varies depending on other system settings.
This mode enables a flag for the domain ID, so that the current domain
setting for the switch is insistent: that is, remains the same over switch
reboots, power cycles, CP failovers, firmware downloads, and fabric
reconfigurations. If a switch does not get the selected insistent domain
ID during a fabric reconfiguration, it segments itself out of the fabric
Default Range

Specify 1 to disable using node WWN when specifying nodes
in the zone database, or specify 0 to enable using node WWN
when specifying nodes in the zone data. The default value is 0.
This value must be set to 1 for interoperability.
