Hi,
I'm running into an issue when I increase the vNIC qty on my blade servers from 6 to 8 or more vNICs and the placement order is not adhered to.
Basically the first 3 vNICs and the last are in order, from 4 onwards its mixed up........
Right now it stops the NFS datastores from mounting as the NFS nics are associated to a different vSwitch and are some of my other NICs
I have tried the following placement order methods - all with the same results
I'm running an A and B MAC pool (Assignment order = Default) and my A and B vNICs were associated accordingly
I've created a new larger MAC pool and set the Assignment Order to Sequential, changed all the vNIC tempaltes to use the new MAC pool, created a new SP-Template and new SP, asscioated the server - still no success
Ive upgraded firmware from 2.2(3g) to 2.2(5b) - no success
Any ideas?
Cheers
Mike

I posted a topic in this forum almost a month ago about this.
I also just closed a TAC case about this. There isn't much Cisco can do about this as its caused by how ESXi deals with enumeration.
It basically came down to my work around (set all VNICs and VHBAs to admin host port one on vcon one) or having to delete all the adapters and reading in esxi anytime you add VNICs. If you go with my work around you don't get the benefit of multiple pci connections. If you go with the VMware method you have a significantly manual process that must be done on every update of nics.
Its not ideal and I wish VMware would handle it better. Hopefully they introduce something in a future release.

Hi Steven, thanks for the update - would you mind if i got the TAC case # so i can reference this for my case?

The engineer provided me bug ID CSCuv34051
08-19-2015 07:24 PM
Thanks - that bug ID isn't even for our relevant hardware as noted above
When I apply the settings as you have mentioned in your post I'm still getting inconsistant placement

Thanks for the reply
Re CSCut78943
There is another bug that stops the AdminHost port due to other Policies - I created a new SP-Template with manual vNIC creation and specified the order - set all vNICs to vCON1, tried;
No success
Re CSCuv34051
There seem to be to many difference
B200M3 vs M4
2.1(3b) vs 2.2(3b) and 2.2(5b)
VIC 1240 vs 1340

Hey,
I totally agree with you on the bug.
However my intent was to provide the solution.
If you read the workaround it kinda solves tour problem.
It also mentions a VMware KB article.
Thanks,

I've looked into the VMware KB a bit more - the remove, boot, add, boot work around seems to work
Thanks

hey thank you.
can you mark the post as answered, it will help other people to find it easier.
thank you again.
08-24-2015 03:54 PM
Done - I've also documented my process in more detail to help
Cheers

After reviewing the VMware KB this "workaround" worked for me

We were running in to same issue, after adding new nics in UCS VMWare will go crazy. All networking will be in mess.
Used below link of VMware to reorder nics and it worked flawlessly after that
