I have a 2 node cluster in windows 2008 R2 AD on an HP Proliant DL380 G6 server with an attached MSA2012sa DAS storage where the resources recite. Resources are mainly data, no apps.
I need to change the IP segment/address of the cluster & storage to a new DS3 circuit. I've tried to follow some of the discussion threads on this topic, but i'm confused.
Please advice the order I should do things:
1. in cluster manager, take resources offline, then change the cluster IP and the resources IP
--is it possible to change ips when it's offline?
--or should I shut down the cluster? is it possible to change when cluster is shut down?
--where does the ip of cluster itself get changed? I rt clicked on the cluster object and there is no option to change it
(in AD or in cluster manager).
2. in network properties of each physical node, change the public IP address
--Should I change one at a time, reboot, then do the other?
--Should changing node ip be done before changing cluster & resources ip?
--anything needs to be done to the quorum disk?
Advice will be very much appreciated. I've read thru a bunch of threads on changing ip but I need to brake it down in order. Thank you.
