Re: How can I convert from Dual Node to Single cluster node

So you have an HA pair and want to take it down to a single node?    Why?  

 

But you'd have to rebuilt it as a single controller cluster.  You can't just remove one node from the pair.

Hi SpindleNinja!

 

Sorry for reply late. For some sensitive reason, I want to rebuild again device with single node. And what I have to do now?

 Please instruct to me detail because I don't know what i have to do first.

Now I just only have a controller, another controller already move to another site. What I have to do for both?

 

Or I just need access to boot menu and choose option: (4) Clear configuration and initialize all disks?

 

Thanks for reply and hope you will help me.

This should get you most of the way there:

I think there's an extra step on the shared chassis boxes to set the chassis mode.  This should cover it:

If you've whacked your aggrs when you tore it apart you'll also need to re-init.  boot menu option 9 to nuke the partitions, set-defaults in the loader, then back to the boot menu and option 4.  You could have some disk ownership by the node thats MIA to sort out too.  Should be fun, but you might need professional help if you aren't skilled in the art.

Looks like you need to make a data aggregate.
