adding vNIC to UCS + vmware

[kthned]

Hi

I am currently working on migrating my VMWare esx host running on UCS to ACI env. 

I am planning to make a disjoint UCS fabric interconnect so that old vlans connect to N5Ks (traditional fabricPath) and the new vlans trunk to ACI leafs (baremetal).

Currenlty my problem is to add a new vNIC under UCS service policy "SP-aci" which is derived from "SP-fp". and then configure vCenter so that the host can be added to ACI distributed virtual switch that was pushed from APIC controller via vmm integration.

Now I write a short procedure and need your valuable feedback if it is possible to do like this

1. From vCenter migrate all VMs from host-107.
2. Shutdown host-107
3. from UCS disassociate SP from host-107
4. Clone current SP to a new SP "SP-aci" [mix because it has FP + ACI vNICs]
5. Add a new vNIC to the newly cloned SP "SP-aci" for ACI and trunk ACI vlans 
6. Associate newly created SP to the server 107 & restart.
7. From vCenter server, add the newly created vmnic from host-107 to ACI distributed switch.

Is there any thing that I need to worry about during the process ? you valuable feedback welcome :)

Greetings.

A couple of items to note:

• configure your disjoint layer2 (prune vlans for your uplink interfaces) before you plug in your new links to the ACI environment.
• After applying new/updated service profile to blade that has additional vnics to carry additional vlans, make sure your check mac addresses and vmnic names to make sure Vsphere hasn't reassigned the vmnic numbers, which can happen when adding new vnics. (i.e. previous VMNIC2 is now VMNIC3)

Thanks,
