Hello,
did anyone notice that the vmnic numbering has been changed in ESXi 5.5? I can't find anything on that topic in the change log, but i confirmed that on a HP server with a fresh installation of an ESXi 5.1 and ESXi 5.5 with the following result. Seems that the numbering is now based on the Slot ID, written to the chassis...
For me, that is an possible issue. When i update a Cluster from 5.1 to 5.5 and add a newly installed 5.5 host later, i have an inconsistent numbering. Any thoughts?
I have a blog on that topic, with some further information: http://www.virten.net/2013/11/vmnicvmhba-sequence-changed-in-esxi-5-5/
