2 portCfgNPIVPort portCfgNPIVPort Synopsis Enables or disables N_Port ID virtualization (NPIV) functionality on a port. [slot/]port mode Description Use this command to enable or disable NPIV functionality on a port. N_Port ID Virtualization (NPIV) enables a single Fibre Channel protocol port to appear as multiple, distinct ports, providing separate port identification within the fabric for each operating system image behind the port as if each operating system image had its own unique physical port. NPIV assigns a different virtual port ID to each Fibre Channel protocol device without impacting your existing hardware implementation. The virtual port has the same properties as an N_Port and is therefore capable of registering with all fabric services. The following conditions must be met for a switch port to respond to NPIV requests from an NPIV device: NPIV capable: NPIV capability is a switch blade or port attribute that is required for NPIV functionality. Some blades within a switch, or some ports within a switch or blade, may not have NPIV capability. NPIV functionality cannot be enabled on such ports and they do not respond to NPIV requests. NPIV enabled: NPIV functionality must be enabled on a port for it to respond to NPIV requests. By default, NPIV is by default enabled. It can be selectively disabled or re-enabled on specified switch ports using this command. NPIV HA: To enable NPIV functionality on dual-CP systems, NPIV-enabled firmware must be running on both the active and the standby CPs. This requirement does not apply to single-CP systems. Up to a maximum of 255 virtual port IDs are allocated per NPIV port. The maximum number of virtual IDs can be configured from 0 to 255 per port. The default value is 126 per port. The number of virtual port IDs per switch can be configured with the configure command. Refer to the Fabric OS Administrator's Guide for details on NPIV configuration procedures. Note Changes made by this command are persistent across switch reboots and power cycles. Use the portCfgShow command to determine whether NPIV is enabled on a port. Use the portCfgDefault command to reset all port configurations, including the NPIV configuration of a port. The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command Availability" for details. Operands This command has the following operands: slot For bladed systems only, specifies the slot number of the port to be configured, followed by a slash (/). port Specifies the number of the port to be configured, relative to its slot for bladed systems. Use switchShow to display a listing of valid ports. mode Enables or disables NPIV on the specified port. Specify 1 to enable or 0 to disable the feature. 618 Fabric OS Command Reference 53-1001337-01
