Does the above statement means, it wll generate its owen entry and we should be able to login again.
I just deleted my own ARP entry. Nothing happened. It didn't even break my SSH connection. When something doesn't know your ARP address, all it has to do is ask. It will automatically do so then carry on without missing a beat.

'Also try logging in from a different server ' I did not understand this. After deleting the ARP entry for the servers HOSTNAME I am not able to login to the server from any servers.
I'm with methyl on this. Unless you had something funky set up like static ARP addresses that cross subnets, deleting an ARP address shouldn't have done anything.
statically set ARP addresses won't autodetect, but I've only seem them used once in my entire life, at all, ever.

And by anychance restarting the server will create the ARP entry again?
I couldn't say until I know what actually happened here.
