SCP command end with Host Key not found in database

Hi,
I'm trying to copy a file from one server to remote server using SCP command. Below is the command i tried and got host key not found in database errror.

scp sendfile.txt Remoteserver:/home/xxxx/.

Error Message:
Host key not found from database
Key fingerprint:
xokin-pumap-tifak-vatal-mukup-cisyk-penuf-dykes-hahuz-kisir-hexax
You can get a public key's fingerprint by running
%ssh-keygen -F Publickey.pub
on the keyfile
Are you sure you want to continue connecting (yes/no) ?

Please help me to fix this issue!

Thanks in advance,
Vasanth.

you will need to save the hostkey file first.
First do a simple "ssh <servername>"
it will ask you the above question you posted to save the file - type in "save"/"yes" whatever it asks.
Once you save the hostkey, you will be able to do the ssh/scp without that question being asked.
