Yesterday I re-setup the VMware environment for my client. There was a weird problem we were facing on the port group from standard vswitch for VMkernel. Here is the step how I create it.
Firstly, I created a new vSwitch, which is vSwitch 1 is this case, and I created 2 extra port group which is NFS1 and NFS2 at the same time with correct ip, subnet and etc. Once I done that, I click ok to apply the configuration. Funny thing happen now, the NFS1 created was working as I can mount the datastore as I need. NFS2 was giving problem which it suppose to point to different storage unit for NFS, it could not reach the storage unit. I try to perform vmkping on the ESX host, and it could not reach the storage host.

It been quite some times I did not migrate the ESX host from 1 vCenter to another. For most of the deployment recently, we were either deploy our vSphere 4 with DVswitch or Nexus 1000V from Cisco. Here are some steps you may want to consider when you migrate the ESX host from 1 vCenter to another if you are using DVswitch. Usually we can disconnect the ESX host from vCenter and remove it from inventory, and reconnect to the new vCenter. If you are follow this way for standard vSwitch, it shouldn’t cause you any problem, but if you deploy this way for the environment which using DVswitch, the new vCenter will give you error which shown the previous DVswitch record are still tie to the ESX host on a different vCenter. Do not get panic as the Network connectivity are still working as usual, but you will not able to connect the ESX host to the new DVSwitch.

The past one week have been busy with VMware vSphere 4 and Cisco Nexus 5000 POC and the result is really disappointed. Personally I couldn’t believed and I think I may missed out something. If anyone have any idea or suggestion, please feel free to comment here or post reply at slow Performance with 10 Gb CNA card on vSphere 4 thread.
