Hi JianGong Dai,
I guess you incorrectly posted it to SIMULATOR page. But thats ok.
This question is more on the physical ontap front.
Aah i read the subject line -- which clearly states your point.
well i will try and answer this one.(though i may be incorrect -- request you to check and post a similar query on ontap community page)
also i would try and find an answer myself because this looks like an interesting scenario too
my answer:
If you buy two physical nodes i would ideally configure both (will not try to have a single node)
Since you have tried to create a single node cluster only . I would ideally bring up the second node with same ontap version
I will have to connect the disk shelf appropriately for HA (as mentioned in my above post)
I would need an interconnect cable running between these clusters nodes
i will make the second node up and join the first node (making it a 2 node cluster)
after this on for HA i will have to enable storage failover on each nodes
storage failover modify -node nodeA -enabled true
storage failover modify -node nodeB -enabled true.
storage failover show (would show me both nodes connected)
