Enabling FlexAttach Virtual pWWN
The FlexAttach virtual pWWN feature is enabled automatically, manually, or by mapping pWWN to
virtual pWWN.
Automatically Enabling FlexAttach Virtual pWWN
The virtual pWWN is enabled automatically on all the NPV switches or per port on the NPV box. When
enabled automatically, a virtual WWN is generated from the device switch WWN. This WWN is used
as the virtual pWWN. Virtual pWWNs are generated using the local switch WWNs.
The port must be in a shut state when the virtual pWWN is enabled.
Note
To enable virtual pWWN automatically for all the interfaces, follow these steps:
From the Device Manger menu bar, select FC > FlexAttach.

Server Mobility—A server can be moved to another port on the same NPV device or another NPV
device without changing the SAN. This is accomplished by moving the virtual pWWN to the new
port. No change is needed if FlexAttach was configured using the physical port WWN of the server
to the virtual port WWN mapping.
FlexAttach configuration is supported only on NPV switches.
Cisco Fabric Services (CFS) IP version 4 (IPv4) distribution should be enabled.
Virtual WWNs should be unique across the fabric.
