Newbie Data Ontap cluster 8.2


Hello Everyone,


I am new to Netapp CDOT so excuse me for stupidity. I was go through the elearning for Ontap cluster fundamental ..this morning.


I have few questions that i tried researching but couldnt find an answer ..I am trying my luck here .


1.  HA pair still exists in Data ontap cluster meaning .. Storage failover must be configured with partner . Help me understand this .. 


Can i have cluster with odd number of nodes i.e  cluster of 3 nodes or 5 nodes ?

Does it have to be in even number so that I can have a partner for each node ?  

If 3 nodes cluster exist , how is HA paired among them ?



2. Can I use ontap 8.3 to simulate failover ?? I read its not possible in ontap 8.2 or below?? How can i test or configure failove in simulator ? 

If you managed to do it .. can you please share procedure ?



3. One last question 🙂 


I just need a high level overview of step by step . ( not in details just a task by task ) > I see there are many helpful blogs on step by step setting cluster ontap.


1 . Create 2 node cluster

2.  Create aggr

3. Create Vserver/SVM

4. Create  file or block protocol LIF for connectivity and volumes 


Since failover isnt possible on simulator .. I want to know opinion from others who are using simulator to practice ? Please give me list of task that i can try on simulator

I went to try failover .it took me lot of effort to understand its not possible . I am tryin to seek help from pro's who have already used simulator and tested functinalites of cluster ontap
