Making a new VLAN available to ESX4 via vNIC Templates
You have several Service Profiles that are associated to blades and running vSphere's ESX4. You have a new network VLAN to make available to vSphere so you need to do three things - all of which are NON-DISRUPTIVE CHANGES, which means NO REBOOTS!
Modify the northbound LAN switches (e.g. a pair of Nexus 5Ks) to allow the new VLAN.
Create the VLAN in UCS Manager and make it available to Service Profiles by modifying a vNIC template
Create a new port group in the vSphere vSwitch to make the VLAN available to virtual machines
This procedure relates to UCS 1.02(d) and ESX4.
For this illustration, the new VLAN is "dmz_84".
This procedure expects you to have two vNIC Templates called vmnic0 and vmnic1. These are Updating templates, and they are used by the ESX4 Service Profiles.
On the Nexus5K
Create the VLAN
Modify the configuration of the ports that are connected to the UCS 6120s to allow the new VLAN.
In LAN --> LAN Cloud --> VLANs, Create VLAN
Configure the new VLAN as "dmz_84" as a Global/Common VLAN with an VLAN ID of 84.
Now the VLAN is available, we need to tell the Service Profiles to make this VLAN available to the blade vNICs. There are two ways to do this:
First, we can hand edit all the Service Profiles to add the new VLAN to each vNIC, or
Make Service Profiles use Updating vNIC Templates - now we make just one edit, and UCS will update all the Service Profiles for us!
Our ESX Service Profiles are using Updating vNIC Templates:
So, we need to edit the vNIC Template vmnic0:
Remember, because this is an Updating template, any changes will be automatically applied to all Service Profiles using this template. These VLAN changes do NOT require a reboot.
All we need to do is click Modify VLANs and add our new VLAN, and Voila!
All Service Profiles using the vmnic0 (and vmnic1 which we would also edit) template will automatically be able to see VLAN 84.
If using normal vSwitches or dvSwitches, you just need to create a new port group with an ID of 84
If using nxSwitch, then create a new port-profile.
Configure your virtual machines' vnics to use the new Port Group with VLAN ID 84.
