I have a pair of 7816MCS'. When we first got the kit we only had the one license node license, so we just started setting up and testing with the first machine (obviously it being the Publisher). Whilst waiting for the other license to arrive I upgraded the Publisher to 6.1(1b).
A few days ago the license arrived, I put it in, the License Unit Report shows it has one more position free.
I tried to upgrade the secondary machine (the Subscriber) and it keeps failing with errors to do with the DB replication failing / not working, which I'm assuming means the DB is not replicated correctly with the Publisher cause it hasn't joined the cluster yet. So on the Subscriber I go to the OS Administration page, goto Settings->IP->Publisher and enter in the IP of the Publisher into the "Host*" field and hit ENTER (or hit the Save button) and ever time the page just refreshes and the field comes back blank again.
What am I doing wrong here?
Can I get a 6.0 Subscriber node to join the 6.1(1b) Publisher? Or does the Subscriber need to be upgraded first? How can I upgrade the Subscriber if its failing do to DB errors?
