How can I convert from Dual Node to Single cluster node

[NghiaTD]

Dear all community!

 I'm a newbie. I have some new Netapp FAS2620 try to convert from Dual Node configure to Single cluster node. But I don't know how to convert, anyone can help me procedure to convert?

Thanks!

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.

Hi SeanHatfield!

I've rebuild single cluster success, but I'm not sure all about my configuration is right!

Can you check for me follow information bellow:

Looks like you need to make a data aggregate.
