a number of months back we upgraded our three server cluster from 4.1.3 upto 6.1.4 then onto 7.0.1. Now sitting at 7.1.2. At the time because of server age we actual bought in three new servers, built the cluster, did dma, then installed onto the new cluster. Three existing servers were switched off. To make it easy we used the same ip-addresses and host names for the new servers, as was on the old ones.
Now we want to re-introduce one of the old servers back into the cluster. (It was actually reasonably new and fits the profile for 7.1.2 hardware).
Question: what do you think is the right way of doing this, remember the server switched off currently has the same ip address and hostname as one of the working servers, and is on a much lower code.
I'm thinking we need to change the hostname and ip address of the server via windows.
Add this address and hostname to the existing cluster.
Put this server back on the network so it can see the pub
Use the install 6.1.4 upgrade disc, then continue until we reach 7.1.2.
