HBA problems only
2
1. Possible Cause: One or both of the required licenses are not installed on the edge switch
connected to the HBA port:
•
Adaptive Networking (AN) license.
•
Server Application Optimization (SAO) license.
Action: Enter the bcu qos --query command for the adapter port connected to the switch. If the
QoS state is “Unknown” instead of “Online” and total BB-Credits is “zero,” licenses may not be
installed. Verify if licenses are installed by executing the Fabric OS licenseshow command on
the switch. Install licenses as required.
For more information about Fabric OS commands and QoS support, refer to the
Fabric OS
Administrator’s Guide
.
2. Possible Cause: QoS is not enabled on both switch and adapter port.
Action: Verify if QoS is enabled for an adapter port using the qos -query <port_id> BCU
command. Verify if it is enabled on the switch using the islShow command.
Action: Verify zones on the switch using the Fabric OS cfgActvShow command.
3. Possible Cause: QoS zones are not created properly on the switch for high, medium, and low
priority targets.
Action: Verify that QoS is configured on the switch using instructions in the
Fabric OS
Administrator’s Guide
.
Quality of Service not functioning
Quality of Service (QoS) is enabled on an adapter port connected to a supported edge switch, but it
does not appear to be functioning.
Possible Cause: The following licenses must be installed:
-
Adaptive Networking (AN) license.
-
Server Application Optimization (SAO) license.
Action: To determine if these licenses are installed on the connected switch, execute the Fabric OS
licenseshow command on the switch. If licenses are not installed, install them. For more
information about Fabric OS commands and QoS support, refer to the
Fabric OS Administrator’s
Guide

Unable to create more than 126 Virtual (NPIV) ports for HBA
If you cannot configure more than 126 N-Port ID Virtualization (NPIV) ports (maximum is 255 for
Fibre Channel) refer to the following descriptions of possible causes and recommended actions to
help resolve the problem.
Possible Cause: The maximum NPIV limit for the connected switch has been reached.
Action: Execute the Fabric OS configure command on the attached switch and change the
maximum logins per port parameter under the F_Port login parameters menu to increase the
maximum NPIV IDs allowed per port.
