Restore Cisco Nexus 1000V - Host-ID fingerprint posted: Jun 16, 2009 11:58 PM

Did anyone find some information on how to restore a Cisco Nexus 1000V?

The license is based on a fingerprint of the host-id from the VSM. In case we loose the VM with the VSM or a ESX host server needs to be reinstalled, this fingerprint is different. So what would mean the licensekey need's to be regenerated.

Has anyone found some information on this?

Tom,

The hostid would most deffinitely change on a reinstall. Which means you would need to rehost license. There is a procedure for this, but it requires that you work with licensing agents on www.cisco.com.

The process is detailed in the License configuration guide on the www.cisco.com website.

Here is a link to the document.

So that explains why vMotion is not supported for the VSM.

The 1000V host-id is tied just to the 1000V. It is not tied to VMware software.

If the VSM is changed/replaced a new license key can be sought as follows:

Step 1: Contact Cisco Global Licensing Operations (GLO) at 800-553-2447 or licensing@cisco.com.
Step 2: Be prepared with following information: Old Hostid, or Original PAK, or Sales Order and Preferred contact method
Step 3: Receive email from Cisco GLO with new license file within 48 hours.

Neal,

You say that vMotion will be fully supported to the 1000v VSM. Does that also mean that the VSM VM can run on the same VEM and ESX cluster that it is managing? If so, that's different from early information I received.

(Sorry to hijack this thread)

Yes you can put the VSM in the same cluster and have the VSM run ontop of a VEM. That will be a supported configuration.

A: We do not recommend it.

Tom,

There must be some misconfiguration. I'm able to migrate my VSM to VEM and migrate service console port with no issues. The VSM is not in the datapath. So if the VSM goes away the VEM will continue to foward packets based on the last known configuration from the VSM.

Now you can't migrate the VSM at the same time you add a host to the VEM. That creates a catch-22 condition. The VEM needs to talk to the VSM , but yet you are migrating the VSM so it has no network connection.

If you have two nics create another vswitch and stick the VSM connections on that vswitch. Migrate your service console and vmk interfaces from the initial vswitch and then create port-profiles for control, packet, and management. Once the VEM is connected and the port-profiles are created you can migrate the VSM to the VEM.

It seems Cisco's recommended setup for the 1000v is to have two VSMs running in your ESX cluster.
