 Issues configuring Distributed vSwitch and Distributed Port Groups in ESXi 8.0u3

Hi,

I am currently setting up 3x new ESXi 8.0u3 hosts in a new cluster, and have plugged in 3 network adapters.

vmnic0 - for iscsi network

vmnic1 & vmnic2 - for management and vm network

The network in vmnic1 & vmnic2 are trunked (i.e. mutiple VLANs)

I have also configured the following for vSwitch:

vSwitch0:

4x VM network

1x Default Management network with vmkernel (vmk0)

Physical Adapters vmnic1 & vmnic2 are connected to vSwitch0

vSwitch1:

1x iSCSI network with vmkernel (vmk1)

Physical Adapter vmnic0 is connected to vSwitch1

I was able to create a new Distributed Switch, and a new Distributed Port Group.

My problem is that when I add Host to the Distributed Switch (in my case i tried to add to 1 host 1st), and when i assign vmk0 to management port group, the task runs and times out, and there is no changes made. There are residual changes made to the host and I had to access the DCUI to run some commands to remove the VDS.

Question: Should I configure vSwitch0 to use one vmnic (i.e. vmnic1) first, have the VDS use vmnic2 as the only uplink first, then migrate vmk0 to the VDS on vmnic2?

Or is there any guides that I can refer to for such cases (only 2 physical adapters)

Thanks in advance!

Hello 

If you want to migrate your phisical and virtual network from vss to vds you should plan it carefully.

you have to have 2 vmnics that connected to the same dc phisical switches with the same access levels on switch ports. then migrate just one vmnic uplink then migrate just one portgroup and check traffic forwarded correctly from the migrated portgroup then migrate all other portgroups and phisical uplinks.
