any consequence if use vCenter's hosts entries 1st during ESXi hosts setup & later create DNS FQDN entry record
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
