Hi Erman,


I have few questions for you on ODA.

Request your help on this :

Node 1 : Prod DB and Prod Application is running.
Node 2 : Test DB and Test Application is running.


a. If Node 1 goes down, how to bring up prod on Node 2? Test and document the steps on Node 2?

b. If Node 2, goes down, what happens to Node 1? Any effect?

c. Can both Prod and Test run on one node at a time?

d. How to create an image of existing VM’s and clone? Is that possible?

I tried updating in your blog. But got error as :

An error occurred while contacting the server.


Thanks,
Manju

Hi,

1)
1 and 2) Your guest vm machines are running from the shared repository, which makes them be available for running on node 1 or node 2.
So if your Node1 goes down, your vm's will be able to start on node 2.
If you set failover -> true , then it will be automatic.
Also you can start the guest machine on your preferred node manually.

3)
Yes they can. Configure them to run on the same node. Configure memory and Vcpus accordingly.

4)
For cloning , you can follow the document below. You will need to adapt that document to your needs.
So you need to archive and zip , it and make the clone using vmtemplate option. You can do it on the same repository , so copying should not take a long time for you.
