DATA CENTER TECHNICAL BRIEF

Setting Up NPIV with Brocade HCM and Microsoft Hyper-V 12 of 12

 To get this detail, run the FOS CLI command nsShow on the switch. In this example, the source is the

virtual port 28:92:00:05:1E:65:8A:CB (Physical Disk 3).

nsShow displays a lot of detail, so to help find the information, use

This displays the data one page at a time.

In this example, these are the details for the source ID (the Hyper-V guest).

Port Number

In order to understand how to set this up, you need to understand how perfTtMon works (Top Talkers). The

I/O transferred is in terms of what the switch sees. In a server/storage configuration, the port is considered

the ingress and the storage the egress. So by adding an ingress to the port number of a server, this is

considered the writes from the server to the storage. If you added an egress on the port with the storage,

this would be reads on the server. In this example, writes to the storage device from the server are shown.



Perfttmon –add ingress 35 (the port with the virtual port).



Perfttmon –show 35. By default, only a certain number of Top Talkers are listed at any one time. If

there are several NPIV ports on a physical port, you will need to show more of the NPIV ports by running

perfttmon –show 35 x (where x is any number). This command does not run continuously, you

have to run it manually. This command samples once every 30 sec and then averages the values. The

first time you run the command, you may see no data, which means either there is no data running, or

that you need to wait longer for the data to be crunched.

NOTE: Two ports are listed: the first one i

s the virtual port and the second is the other virtual port on that

physical port. Since the physical port is not listed (nor zoned), no traffic is being used by the physical port.
