vsphere 7.x
DNS settings are not correct for vCenter and need to be corrected in the customer environment
Run the following commands to verify customer DNS setup.
- Check Forward and Reverse DNS Resolution for this VC PNID and share the output.# nslookup <vCenter FQDN> <vCenter IP address>
# nslookup <DNS server> <vCenter IP address>
# nslookup <vCenter FQDN> <vCenter IP address>
- Share the output of:
# hostname -f
# cat /etc/hostname
# /usr/lib/vmware-vmafd/bin/vmafd-cli get-pnid --server-name localhost
Both forward and reverse DNS resolution should be accurate, and should match the vCenter PNID and the IP address on the Primary vmnic on the vCenter VM.
This backup issue is essentially caused due to this secondary interface and IP, and the resolution surrounding it.
