Error while configuring Content server

Hello,

I have installed a new CS on a server and trying to configure it from SAP system.

I have used all the Transaction like CSadmin, OAC0 and able to configure it but have some doubts and also facing some issues like:

1) How I can check if the CS configuration is fine and correct?

2) The status of contREp is not showing running rather is is showing " data(77%) log(0%)".

3) I have one other CS configured in SAP system , so will it make any difference? I hope it should not.

4) should i define the content server ip in the host file at OS system of SAP system's ?

Regards,

Bhavesh
