Lance's Random Ramblings
I was struggeling with an install of ESXi on a cisco 6509 switch where the management and VM LAN connectivity worked just fine but for some reason the SAN NFS VLAN just did not want to communicate with the Nexenta on that VLAn.
After some searching and trial and error I was able to utilise this post http://blogs.egroup-us.com/?p=2453 to get the port-channel and the ports configured correctly. I did not use all the settings from this post but it did remind me to check my port0-channel config.
I am busy working on a contract with a comonay that is implementing a 10G network for their ESX cluster.
We have been using extreme X650 10G copper switches for the core.
Migrating the current servers to the 10G environment was relatively easy and went with minimal issues.
Over the last 2 weeks I have been trying to get a new server to connect to the cluster ahnd have been frustrated. I have been unable to get the server communicating on the management VLAN. the server was configured correctly and so was the switch or so I thought.
It seems that to make this work you need to add the network cards to the vlan in the extreme os as untagged which then allows you to connect the server to vCenter and then once you add your NIC’s to the dv switch you lose connectivity again and have to readd the ports to the management vlan as tagged.
this post is more fo rme to be able to look it up in the future.
