That's correct. Changing the hardware will change the hostid of the NetWorker server. You will have to re-register your new hostid on powerlink or mail EMC Licensing team.

It all depends how hostid is generated. On most of the platforms change of HW will trigger different hostid. In the past, for AIX, following claim was correct:
"The gethostid subroutine allows a process to retrieve the 32-bit identifier for the current host. In most cases, the host ID is stored in network standard byte order and is a DARPA Internet address for a local machine" There is the function sethostid() available for AIX which allows changing the host id."
So, if hostid is generated only out of IP address then it won't change. One way to check it is via uname -i.
