Problem with vhba and dynamic vnic placement

Hello all,

I have a problem with vnic/vhba placement policies on an UCS-B:

When a configure a Service Profile, evrything is good:

- I use a "specify manualy" vnic/vhba placement policy  and can create this configuration:

- vhba 0 : Order 1

- vhba 1 : Order 2

- veth0 : Order 3

- veth1 : Order 4

- veth 2: Order 5

- veth 3: Order 6

- 8 Dynamic vnic : Order 7 to 14

As soon as i associate this SP with a B200M2 (with palo), UCS manager change this order like that:

- veth0 : Order 1

- veth1 : Order 2

- veth 2: Order 3

- veth 3: Order 4

- 8 Dynamic vnic : Order 5 to 12

- vhba 0 : Order 13

- vhba 1 : Order 14

I've tried several placement policies (auto, exclude dynamique from vcon 1, ....) but it's still the same.

I need to maintain previous order with first vhba, then vnic and finaly dynamic vnic...

My config:

- 1* UCS 5108

- 4 *UCS B200M2 with palo adapter

- UCS MANAGER 2.0(1q)

Does someone know this problem and how to solve it ?

Thanks in advance

Problem with vhba and dynamic vnic placement


When using dynamic vNICs you can't define more than one physical NIC (eth0 and eth1).  If you try to create more than two vNICs (using a single VIC) with a Dynamic vNIC policy, it should error out on you during association.

The vCon connection policy is really only used for full width blades with dual mezz cards populated.  This gives you some control as to which mezz card and interface vNIC/vHBAs are placed on.

With a B200, the only virtual PCI slots you'll have will be 1 and 2.  To my understanding you need the vHBA's as the lowest PCI device # - is that correct?

For your placement policy, set slot 1 to be "Assigned Only", and leave the rest set as "All".  Next assign your vHBAs both to Slot 1, and click ok.  Associate the Service Profile to the blade and report the results.

This should set the desired placement and ordering for your vHBAs as the lowest.

Problem with vhba and dynamic vnic placement

I've made all those changes :

Vconn1: assigned only:

     - Vhba0   1

     - Vhba1    2

Vconn2: All

Vnic eth0, Vnic eth1 are not assigned anywhere

One dynamic vnic policy with 8 vnic

But the result is still the same:

Vhba1 is ordered 11

Vhba2 is ordered 12

Vnic eth0 is ordered 1

Vnic eth1 is ordered 2

Dynamic Vnic are ordered from 3 to 10
