Symmetrix composite groups
I would like to create a composite group from 2 existing device groups. Is there an easy way to do this?

I guess I missed an important question as well.
Do you want to do this migration without affecting any RDF connections already in place, or are you OK with resynching everything from scratch?426

I assumed I would need to resynch. Going forward, I will only be using the composite group.426

Thanks, that's what I did. I exported both groups, combined the files, put 'CGTYPE_REGULAR' as the first line, and imported it. I was just wondering if there was a more elegant way!
Thanks for your time.426

No problem. When it comes to this stuff there is rarely anything I would call and "elegant way"... I generally look for the "least painful way" and hope that it doesn't have any hidden gotchas426

You could use the following SE command:
symdg dg2cg DG1 CG
symdg dg2cg DG2 CG
This works fairly well and is what we use with our MSC Consistency Groups.
You can then remove the DG if you do not plan on ever using them though it is OK to have DGs and CGs containing the same devices on the same host and can be nice if you need to handle them differently.426

Wow, not sure how I missed that one. I saw your note and immediately grabbed my handy SymCLI reference, and today "dg2cg" was there (I swear it wasn't there yesterday)101

Hi SANGoddess,
I moved this thread to the Solutions Enabler forum because it is more focused on SE than ControlCenter.

If you still want to accomplish this in SE you can probably do an export of the two DGs and then manually edit the file before importing into the CG. This is likely the first thing I would try.
There are some commands for moving devices between CGs, and even between DGs in newer code) but I can't find anything to directly move from one or more DGs to a CG.
Anyone else have any great ideas?
