This is a vSphere 6.7 update 3 environment. VCSA is 220.127.116.11100 build 16275304. Hosts are 6.7.0 Update 3 build 16316930.
I recently swapped out my Edgerouter X for a pfSense appliance, and while everything seemed to come back online fine after the move my VCSA is having a bad time of it.
The host name and IP address of the VCSA has not changed.
Health status is all good in the VAMI, and SSO shows as running with the vsphere.local domain.
The VCSA is joined to my active directory domain run on two win2019 VMs on the same network.
DNS is set up on the pfSense box to point to both Windows domain controllers which have static A records created for the VCSA and other infrastructure pieces like the hosts and VMs.
I also have forwarders configured on each domain controller to point to a set of pi-holes for external resolution to Cloudflare.
Before making the router switch I shut everything down, VMs, hosts, switches, Synology, modem. I set up the new pfSense box, set up the reservations to give the same address to everything and brought them back online in reverse.
Now when logging into the VCSA both hosts shows as not responding and all VMs show as disconnected. I try to connect the hosts but it fails before even trying to authenticate saying, “The host may not be available on the network, a network configuration problem may exist, or the management services on this host may not be responding.” However, I can connect directly to the hosts.
It seems clear that this is DNS related, but I can’t imagine what is different as I feel like I set it up on pfSense the same as it was on the ERX.
VCSA backup also fails with the message, “Backup PNID ‘vcsa.my.domain’ is not resolved on the network. Configure the network DNS service accordingly.”
Any ideas what I did here, and how I can get things back on track?
