Discover WWNs on NPIV

  • 1.  Discover WWNs on NPIV

    Posted 02-04-2013 01:58 AM


    I have some ports on SAN768b switch with NPIV config.

    When I run switchshow, the only information that I can get is:

    131   13   03fc80   idN4   Online  FC  F-Port  1 N Port + 4 NPIV public

    We have a performance issue with VMWare, and I can't identify which port these servers are connected. The only information is the zone (where I can identify the WWNs)

    Is there any way to discover the WWNs of these HBAs?

    portshow 13 or nsshow (the alpa part of the FID would change and Domain and Area part would remain the same for each WWN for port 13)

    Hi Marcia,

    portLoginShow shows all WWNs logged into fabric on a given physical port.

    If you know device WWN you can further identify it with nodeFind command.

    nsZoneMember might tell you with what other devices your host WWN can communicate.

    Hope this helps,

    We do a ton of NPIV and the best way that I have found to ID the port is using DCFM/BNA. Easy way here is to right click on the switch in DCFM/BNA and click on performance monitor/ real time graph. Look for your NPIV WWN and you will see the actual port number above it. Hope this helps
