Dear all
Hi
As our vcsa fail and vm network is connected on VDS we can not change network adapter port group
now i want to know due vds config if i set Port binding on Ephemeral-no binding is that possible change
network port group for each vm after vcenter fail
BR
Babak
Yes
"Ephemeral" port groups can be used even without vCenter Server up, and running.
Hint: If the Embedded Host Client doesn't show the ephemeral port groups (which I consider being a bug), you may use VMRC to reconfigure network settings for a VM.
I usually create one ephemeral port group for the vCenter Server's network, so that it is possible to fix issued with vCenter Server itself.
André
So thanks
Do you suggest use ephemetal-no binding instead of static binding for all of portgroup on VDS ?
BR
No, it should not be done for all VM port groups. Only for the port group used by vCenter as a rescue.
So thanks
but could not understand the reason for assign vcenter port group on ephemeral-no binding because if my vcenter fail and down i could not change network adapter portgroup for other vms
but you said just change port binding type for vCenter why ?
BR
If vCenter is down your VMs do not lose connectivity on their current port groups, so there is no need to reassign them to other port groups. What matters is getting vCenter back online, and for that you may need an ephemeral port group (or multiple) dependingdon your network.
It's actually about performance, statistics, overhead, etc. why you should not use ephemeral port groups by default.
What you may do, it to create an additional ephemeral port group for each of your VLANs for disaster recovery purposes to be e.g. able to create new VMs while vCenter Server isn't available. Once it becomes available again, reconfigure the newly create VM, and attach it to a static port group.

imagine i have a vswitch and one vds while my vcenter goes down i could not change my vm port group in edit setting but if i set my port binding type on ehemeral if my vcenter fail i can change vm
network from vds to vss in vm edit setting
is that correct ?
BR
Not exactly.
You can change your VM's network settings - no matter what's currently configured - to an ephemeral, or VSS port group.
André
Also, how often is your vCenter down at the moment when you absolutely must change a VM's port group? Because if that's happening frequently, something is wrong with your environment.
if my vcenetr goes down can i change my vm's port group from VDS to vss by connect direct to esxi host ?
if my vcenetr goes down can i change my vm's port group from VDS port group1 to VDS portgroup2 by connect direct to esxi host ?
BR

Yes.
if my vcenetr goes down can i change my vm's port group from VDS port group1 to VDS portgroup2 by connect direct to esxi host ?
You can only change to ephemeral port groups.
André
i could not understand why you say use ephemeral port binding type just for vcenter port group ?
if vcenter goes down can i change vm's port group from vss to vds ?
BR

That's how I do it.
if vcenter goes down can i change vm's port group from vss to vds ?
Not unless you you have ephemeral port groups.
Please ask yourself, how often will you need to change network settings for VMs while vCenter Server is down?
In case vCenter Server is down, I 'd rather try to make it working again, rather than changing network settings for VMs.
As mentioned earlier, it's basically up to you to create ephemeral port groups for each VLAN.
