The system creates the new virtual port, for example:(Create Virtual Port Menu)Enter Selection: 2Enter Hex Pattern : EFThe system returns the following:Virtual Port 21-EF-00-8B-14-5A-CF created successfully on HBAinstance 4.Note that the entered hex digits, EF, now appear in byte 1 of the new virtual portWWPN.To see the change to the virtual ports, you must manually refresh theconfiguration.QoS Menu(Command Line Option -qos)15: QoSQoS (quality of service) refers to service level agreement (SLA) to ensurebusiness continuity when transmitting data over virtual ports by either settingpriorities or allocating bandwidth. SANsurfer FC/CNA HBA CLI provides aneasy-to-use interface that lets you assign QoS to virtual ports by either settingpriorities or allocating bandwidth to them: Setting the QoS by bandwidth lets you allocate up to 80% of the numberof gigabits per second (Gbps) transmission speed of the physical port'scapacity to its defined virtual ports (NPIV). Using this feature lets youguarantee a transmission rate for each virtual port that requires a specificbandwidth to run mission-critical applications for business continuity usingvirtual ports. The setting for a given QoS can resolve bottlenecks that existwhen virtual machines contend for port bandwidth.NOTE:The QoS Menu option is available only for Windows operating systems and8Gb and 10Gb adapters. For Windows Server 2008, QoS is supported onlywith MSI-X enabled.
