Mapping Pwwn To Virtual Pwwn - Cisco MDS 9000 Series Configuration Manual

Configuring FlexAttach Virtual pWWN
• The port must be in a shut state when a virtual pWWN is assigned.
Step 1 Enter configuration mode:
Example:
switch# configure terminal
Step 2 Configure the FlexAttach virtual pWWN for the interface:
Example:
switch(config)# flex-attach virtual-pwwn vpwwn interface interface
(Optional) Configure the FlexAttach virtual pWWN for the interface in the VSAN:
switch(config)# flex-attach virtual-pwwn vpwwn interface interface [ vsan vsan]
Step 3 Commit the configuration:
switch(config)# flex-attach commit

Mapping pWWN to Virtual pWWN

You can configure virtual pWWNs through real pWWNs. This process is required for NPIV hosts containing
multiple pWWNs, of which only FLOGI is mapped to the virtual pWWN. Subsequent FDSIDs will have
different mappings.
Several checks are done by the NPV core to ensure the uniqueness of virtual pWWNs in the switch across
the NPV switches. When duplicate virtual pWWNs are configured, the subsequent logins are rejected by the
NPV core switch.
Restrictions
• The specified virtual pWWN and the real pWWN must not be logged in.
• To map pWWN to virtual pWWN, perform this task:
Before you begin
The interface must be in a shut state and the specified virtual pWWN should not be logged in.
