vCenter and PSC on VDS ephemeral port has issues

Hi. We use VDS only, and in our management cluster which has the PSCs and vCenters we put them on Ephemeral ports. But this always seems to happen lately.

If we shut down down the PSC (or vCenter too I am sure when I try it) that is the SSO for the vCenter which manages that management cluster, of course I have to power it up via the ESXi host. Because of course vCenter for that cluster is down.

However whenever I power it on, there will be no networkinging until I disconnect/reconnect the network in the PSC VM edit settings. I have no idea why. This is an ephemeral port so it is available etc when vCenter is down. But why do I have to disconnect/reconnect the port on power cycle just to get networking to work?

It makes me want to redesign and use standard switches. And we wanted to use standard switches, but our NSX deployment the installers insisted we had to use the VMware validated design which calls for all VDS and ephemeral. We wanted to use standard switch for our vCenters and PSC and hypervisors.

So I am confused why this is happening. Thanks,,,

Hi Jeffery,

This sounds like a bug. You should not have to disconnect/reconnect the NIC/network.

What version of VVD/vSphere are you running?

In a VVD there will always be 2 PSCs, highly-available.

Perhaps it is a bug. I do not remember what version of VVD. But I may go back and move our vCenter and hypervisors to Standard Switches. Though that is some work. And also that leaves me with 2 unused uplinks no our VDS. Which always drives me crazy, and no way to delete them.

I assume VVD has changed anyway, since PSCs are being deprecated.

VVD uses distributed switches, no standard vSwitches. You can have 4 NICs in the distributed switch.

I suggest you file a support request, as this behavior is unexpected.

VVD still uses external PSCs, for now. It will change.
