Nexus 1000V - Can not see VEM in VSM

c_simon

Level 1

Hello,

We are trying the version 4.0(4)SV1(2) and we can not see the VEM in the VSM yet. We don't see the "System Uplink" port profile assigned to a physical interface and we think that maybe this is the problem.

This is our config of port-profile

port-profile type ethernet system-uplink
  vmware port-group
  switchport mode trunk
  switchport trunk allowed vlan all
  no shutdown
  system vlan 22-23
  state enabled

port-profile type vethernet vlan-22
  vmware port-group
  switchport mode access
  switchport access vlan 22
  no shutdown
  state enabled
port-profile type vethernet vlan-23
  vmware port-group
  switchport mode access
  switchport access vlan 23
  no shutdown
  state enabled

svs-domain
  domain id 50
  control vlan 22
  packet vlan 23
  svs mode L2

Thank you! Celeste

Simon,

This issue can be caused by multiple reasons but there are few things to check first at initial configuration. Your vem, esx host, has to communicate to vsm on control vlan. This is like backplane on your switch. One way to verify end-to-end connectivity for control vlan is creating secondary service console interface with control vlan port-group. This doesn't have to be routable. Just between hosts, especially the host that has vsm and other hosts with vem.

Once that is verified then you can do the same thing for packet vlan to make sure. Next step is to check if you have installed the vem installation. You can login to esx host as root privilege and do vem status. Then it will tell you if vem is running or not. Also, you can check the license issue as well

Hi Kang,

We test the connectivity with our Packet and Control Vlans, and it works fine, but we still not seeing the VEM in VSM

The sh module vem mapping shows nothing:

VSM-1000v# sh module vem mapping

Mod     Status          UUID                                    License Status

---     -----------     ------------------------------------    --------------

VSM-1000v#

And the vem status command in ESX shows that the agent is running and loaded.

VSM and VM are running on the same ESX host.

Thank you!

Celeste

If you are sure control, packet vlan have configured correctly, then you can try to remove that host from dvs and add back in. It is better to choose the vmnic when you add the host to the N1K rather than adding it later. N1K needs at least one vmnic to connect to vsm. This has to be mapped on your system uplink.

Then you can try to restart the host or vem restart on the host.

thanks

Hello,

we do have the same Problem.

Installed is the Nexus1000v.4.0.4.SV1.3a

The latest VEM (VEM410-201007311) is installed on ESXi4.1

Packet VLAN and Control VLAN are testet. Communication works fine.

The Hosts don't register to the VSM.

VSM Logging says:

2010 Oct  7 17:05:24 DF-ESX-V-01-PRZ %VMS-5-DVS_HOSTMEMBER_INFO: A host with name=[HOST2] and uuid=[a62ba661-7
74b-3f10-0069-00238b428590] is added to the dvs. The host is not found  as a module in the VSM configuration.

We have Installed the VEM manually, per VUM and automaticaly per VUM.

Jean

Is your VSM running on the N1KV port profiles vlan-22 and vlan-23 for the control and packet interface? If so, you'll have to make both of those system vlans in the port profile as well.

Also have you added your pnic to the uplink port profile from the DVS networking view on the host?

Thanks,

sachin

Hello Sachin,

we use VLAN 900 and 901 for Packet and Control.

Both VLANs are defined as system vlans.

Regards

Jean

Could you post the port profile config for your uplink/veth profiles, svs connection and svs domain if possible?

Also could you paste the output of vemcmd show version on the host.

thanks,

sachin

vemcmd show version

VEM Version: 4.0.4.1.3.1.0-2.0.3

VSM Version: 4.0(4)SV1(3a)

System Version: VMware ESXi 4.1.0 Releasebuild-260247

Hi Jean,


Based on the port profile names, I am guessing that the VSM is on the VEM with InfraAccess-VSM-Control and InfraAccess-VSM-Packet as the control and packet port groups for the VSM VM. If so, the vlans on these port profiles 901/900 should be defined as system vlans as well.


Hope this helps


Thanks,

Sachin

Hi Sachin, sorry for responding so late.at the moment we have Standard VS.the VSM is connected to 3 Portgroups; Management, Control and PacketThe VLAN IDs of Packet and Control are corresponding the VLAN IDs of the VSM. Because no host is connected to the VSM, we can't use InfraAccess-VSM-Control and InfraAccess-VSM-Packet.We're still at the beginning :( RegardsJean

Last Update.

i configured the system vlans on the corresponding portgroups on the VSM.

No Connection :(

Hi Sachin,

after adding "channel-group auto mode on" to all Uplink Portgroups, the VEMs registred.

Regards

Jean

In case anyone else runs across this thread (as I did in troubeshooting a similar issue) I wanted to share what fixed it for me.  In my case, I had accidentally added the ESX Host to the wrong VSM.  I removed the host from the VSM and added it to the correct one, but it still seemed to be broken.  I followed all of the steps in this document:

http://www.cisco.com/en/US/docs/switches/datacenter/nexus1000/sw/4_0/troubleshooting/configuration/guide/trouble_5modules.html#wp1192946

However, everything checked out according to the document.  As a last resort, I decided to remove the ESX Host from the vDS and uninstall the VEM using the command "vem-remove -d" at the ESX host.  I then added the host back to the correct vDS, and the issue was resolved!  I had removed and added the host back many, many times, so I am certain the uninstalling the VEM and having VUM reinstall it is what resolved the issue.  If the above Cisco document does not shed any light, uninstalling and reinstalling the VEM may be useful for you.
