Hi,
Just wondering this...
If I have a HA environment with 2 nodes, and the nodes stop seeing each other (network disconnect), what is the default behavior? I'm assuming that in order to be HA, they need to both stay up and running.
But then what happens when network connectivity between them is restored? Does the administrator have to choose which copy survives? If so, can that be done differently on a per-LUN basis, or do you just choose a surviving server?
Also, on a 2 node HA network, can you easily upgrade it to a 3 node network and pay the difference in licensing? Can this be done without downtime?
