1000V no longer creates port groups in vCenter

(Bit of a newbie when it comes to 1000V. Apologies in advance if I'm using the wrong terminology.)

I have two separate 1000V environments and both worked perfectly up until a few days ago. Now, however, one of them has stopped syncing up with vCenter. Previously, when I created a port profile and entered the "state enabled" command, the port group would immediately appear in vCenter. Now, nothing.

If I do "show svs connections" I see the correct vCenter IP address, with config status "Enabled", operational status "Connected" and sync status "Complete". At this point I'm stumped!

Can anyone offer some troubleshooting suggestions so that I can get back on track? Naturally, I have new customers eager to 1000Vget up and running who are stuck without connectivity at this point.

Re: 1000V no longer creates port groups in vCenter

Hi Mathew,

I don't think you have used even a single incorrect terminology. Important is what changes were made? vCenter upgrade/ESXi upgrade/VEM or VSM upgrade

 

Could you please provide the below output? 

1. show module 

2. show svs connection 

3. show vms internal event-history errors | last 50 (where enabling the port-group)

4. show running-config port-profile <name>

 

In the mean time, please try below after getting above outputs: (No impact)

#config t
#svs connect <connection-name>
#no svs connect   ***let complete*
#show detail
#connect   *****to re-connect*
#show detail

Check this: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCuv97166/?reffering_site=dumpcr . I don't know what is the running version, so just suspecting above bug. 

 

Please rate if you find it helpful.

Re: 1000V no longer creates port groups in vCenter

Hi MJ, thanks for your reply.

Here's the output you requested: https://pastebin.com/dDhVYBh6

Note the failed part at the end where I tried to do 'svs connect <connection-name>'. I assumed the connection name was the 'VC01' part from the output of 'show svs connection'. Is that not the case?

Hi Mathew,

 

Sorry for delay response. I saw lot of soap error, lets re-initialize the connection b/w VC & N1kv. 

 

V13005NX1001(config)# svs connect VC01

V13005NX1001(config-svs-conn)# no connect 

*****Check the connection state ( show svs connections)***  

operational status: Disconnected

V13005NX1001(config-svs-conn)# connect 

*****Check the connection state ( show svs connections)***  

operational status: Connected
sync status: in progress

Re: 1000V no longer creates port groups in vCenter

Hi MJ,

 

I successfully disconnected/reconnected and now new port profiles are getting created in vCenter. However, I now seem to have another (related?) problem: new VLANs are only appearing on a couple of ESXi hosts.

To test, I created a new VLAN:

- vlan 2600

- name vlan-test

- state active

- no shutdown

 

Then I added it to the uplink port:

- port-profile HCS-UPLINK

- switchport trunk allowed vlan add 2600

 

Then I created a new port profile:

- port-profile type vethernet matt-test

- vmware port-group

- switchport mode access

- switchport access vlan 2600

- no shutdown

- state enabled

 

The port profile was created correctly in the switch and in vCenter, but as you can see from the above pic, vlan 2600 only appears on a couple of the hosts in the port list. I would expect it to show up on all of them.

 

Any ideas what's happening here?

I forgot to answer this: no changes have been made at all, as far as I'm aware. A week or so ago it worked just fine and now it no longer updates the vCenter.

Re: 1000V no longer creates port groups in vCenter

After further testing and monitoring, the problem seems to be intermittent and not quite as simple as a new port-profile not being pushed out to the dvSwitch in vCenter.

 

For a recent port profile I created, I've discovered that only one of the ESXi hosts has its VLAN listed in the uplink port - i.e. if I click the uplink port andthen the 'Ports' tab, I can see the list of ports and associated ESXi hosts, VLAN IDs, etc., but the new VLAN associated with the new port-profile I created shows up on only one host.

 

Also, in general, the list of VLANs in that screen is quite different for the hosts, whereas I would expect every host to show the same VLANs (because they're all connected to the same vSwitch and, then, to the same 1000V switch).

I'm thoroughly confused at this point!
