My vendors are here setting up 5x ESXi hosts for me but they just
requested for FQDN (fully qualified domain names) to be registered
first for these 5 ESXi hosts in the DNS.
However, it will take 2 weeks for the Change Request to be approved
to create the 5 servers' DNS entries / records.
In the meanwhile, to get the job started, can I just define these 5
servers in the vCenter (or vSphere's ) hosts file first, & once the
DNS entries have been created, we'll remove from hosts file?
I was told by vendor that using hosts file may cause intermittent
instability & corrupt the vCentre subsequently & may require the
whole vCentre to be reinstalled. Vendor said he has also seen
the ESXi hosts may face intermittent disconnects from LAN/storage
when we migrate from hosts to DNS subsequently. They said it's
best practice to start with FQDN using DNS entries from the start
& not switch from hosts to DNS. Are these claims true ??
We're using Windows 2000/2008 DNS
