Clone a RHEL6.4 server on identical hardware, what to reconfigure?

Latest response

Hello

I have two identical physical servers, one of them (server1) is ready configured (users, software) and operational.

Now I take the system disk of server2, insert it into server1 (hot pluggable) and clone the system disk1 with dd to disk2.

Then put the disk2 into server2 and boot the server without network cable.

Then I change the server name and ip adress.

What else to I have to reconfigure (devices, wwn, Linux-ID of the server)?

Do I have to register the server2 in RHN too (have a license for two physical servers, server1 already registered)?

I'm new to RHEL, coming from Solaris :-)

Kind regards
