HP StorageWorks 8/20q Command Line Interface Guide

196 Command Reference
ARB_FF Send ARB_FF (True) instead of IDLEs (False) on the loop. The default is
False.
InteropCredit Interoperability credit. The number of buffer-to-buffer credits per port. 0
means the default is unchanged. Default buffer-to-buffer credits are 16
per port.
Changing interoperability credits is necessary only for E_Ports that are
connected to non-FC-SW-2-compliant switches. Contact your authorized
maintenance provider for assistance in using this feature.
FANEnable Fabric address notification. Enables (True) or disables (False) the
communication of the FL_Port address, port name, and node name to the
logged-in NL_Port. The default is True.
AutoPerfTuning Automatic performance tuning for FL_Ports only. The default is True.
• If AutoPerfTuning is enabled (True) and the port is an FL_Port,
MFSEnable is automatically enabled. LCFEnable and VIEnable
are overridden to False.
• If AutoPerfTuning is disabled (False), MFSEnable,
LCFEnable, and VIEnable retain their original values.
LCFEnable Link control frame preference routing. This parameter appears only if
AutoPerfTuning is False. Enables (True) or disables (False)
preferred routing of frames with R_CTL = 1100 (Class 2 responses). The
default is False. Enabling LCFEnable will disable MFSEnable.
MFSEnable Multi-Frame Sequence bundling. This parameter appears only if
AutoPerfTuning is False. Prevents (True) or allows (False) the
interleaving of frames in a sequence. The default is False. Enabling
MFSEnable disables LCFEnable and VIEnable.
VIEnable Virtual Interface (VI) preference routing. This parameter appears only if
AutoPerfTuning is False. Enables (True) or disables (False) VI
preference routing. The default is False. Enabling VIEnable will
disable MFSEnable.
MSEnable Management server enable. Enables (True) or disables (False)
management server on this port. The default is True.
NoClose Loop circuit closure prevention. Enables (True) or disables (False) the
loop’s ability to remain in the open state indefinitely. True reduces the
amount of arbitration on a loop when there is only one device on the
loop. The default is False.
IOStreamGuard Enables or disables the suppression of RSCN messages.
IOStreamGuard can have the following values:
• Enable—Suppresses the reception of RSCN messages from other
ports for which IOStreamGuard is enabled.
• Disable—Allows free transmission and reception of RSCN
messages.
• Auto—Suppresses the reception of RSCN messages when the port is
connected to an initiator device with a QLogic HBA. For older QLogic
HBAs, such as the QLA2200, the DeviceScanEnabled parameter
must also be enabled. The default is Auto.
PDISCPingEnable Enables (True) or disables (False) the transmission of ping messages
from the switch to all devices on a loop port. The default is True.
