Changing IP adress plantnetwork
Possible, but would probably require a process shutdown as critical nodes would not be able to communicate during the change.
A domain controller updates it own A-records in DNS. Should work by itself.
System 800xA uses RNRP to update the hosts file in each machine with all required addresses. DNS is more or less bypassed for 800xA node-2-node communication.
- Shut down process
- Stop system (or simply stop the "ABB Service Manager service" in server nodes)
- Change IP in domain controllers, reboot
- Change IP in servers, reboot
- Change IP in clients, reboot
After all nodes have been changed, check DNS to be OK (remove any obsolete A and PTR records in the forward and reverse zones). Review RNRP monitor to show a complete list of all nodes, then check the hosts files (or RNRP Wizard can update all files in a few clicks).
- Start system
- Change any dependant setting, e.g. IP address in OPC Server Panel for AC 800M, etc.
- Verify all services to be running, logs collecting, OPC data available, etc
- Startup process
The procedure could probably be made in many different ways, but the above should be the essence of it.
I agree with Stefan,and i would like to add some more points
Always be sure that you are going to change only IP OR Subnetting as well then in this case you should be aware of the tested IP scheme with subnet for 800xA to run without any issues.
Always change the IP address in the following order DC's (PDC,ADC),Pri-AS,Sec-AS,pri-CS,Sec-CS,client nodes,OPC settings if any controller IP address change(verify)
with system stop required.
1.After Changing the IP address of PDC and ADC perform the steps individually
Reboot the Server
ipconfig /flushdns to remove the cache DNS entries
Ipconfig /registerdns to register the new ip address
dcdiag /fix to update the records should run successfully.
check the net share
try to perform the force replication and check its working fine
check the attempts by:repadmin /showrepl
2.In 800xA first change the Ip address in Pri-As, Sec-as and soon
reboot the server and run Ipconfig /registerdns to register the new ip address in DNS
check the system/service event list for the aspect directory successfully loaded between aspect servers.
ensure RNRP is showing all nodes in machines,perform the ping -a for address resolution.
3.if you are using time sync then ensure gateway of CS ip address in the GPS to be changed to sync domain servers.
check if any error events in the eventviewer
