VEM module show an IP assigned to a NIC for the ISCSI.

[gloubier]

Hi,

With the help of the VMware sys admin I have almost finish to setup a new Nexus 1000v configuration with 2x VSM and 1x VEM ( temporary ).

I was lookinkg at the config and found that the IP associated to the VEM is a IP used for the ISCSI, so it's not even routed internaly in our LAN or DMZ.

From the Nexus :

swuapdmz03# show module

3    10.11.43.9       4c4c4544-0037-5810-8035-b7c04f585631  dmz01.ca <--- That's an IP for the ISCSI.

How is it possible? Any idea?

Thanks.

Hello Guillaume,

Can you please share the output of following commands from VSM

show int virtual

show run int vethX

Do you have multiple vmkernel interfaces on that host ?

Hi Padma,

Here the outptu from the 2 commands :

dmz03# show int virtual

-------------------------------------------------------------------------------
Port        Adapter        Owner                    Mod Host
-------------------------------------------------------------------------------
Veth1       vmk5           VMware VMkernel          3   esx03.uuu.com
Veth3       vmk0           VMware VMkernel          3   esx03.uuu.com
dmz03# sh run int vethernet 3

!Command: show running-config interface Vethernet3
!Time: Fri Jan 18 08:14:20 2013

version 4.2(1)SV2(1.1)

interface Vethernet3
  inherit port-profile service_console
  description VMware VMkernel, vmk0
  vmware dvport 609 dvswitch uuid "e4 b8 34 50 86 40 5b 65-20 ad 00 6d 19 71 74 b1"
  vmware vm mac 90B1.1C11.D90B

There's 2 vkernel that are used for the ISCSI but they haven't be added to the vswitch config.

Thanks.

Guillaume
