I have an old NetApp filer that exports volumes via NFS for my UNIX hosts.
We want to migrate it to the new filer and keep name of the old one as DNS alias to the new filer name with new IP address.
The question is will UNIX NFS client that still pointing to the old filer name be able to mount the volume from the physically new filer? Cashed MAC addresses discussion aside, please. I understand that.
Or to show it in the example
On the UNIX client:
Will this last command work or it will end up with error message "permission denied", because of the mismatch between used alias and reverse DNS?
Some links to the theory of this process will also be welcomed.
Best regards
Leonid

It is not what I was looking for, gentlemen.
I know how to handle the situation. I wanted to know why it may or may not work.

I am trying to setup a CentOS 6.2 server that will be doing 3 things DHCP, DNS & Samba for a very small office (2 users). The idea being this will replace a very old Win2k server. The users are all windows based clients so only the server will be Linux based.
