Anyone familiar with EMC SANs? I have a snapshot question.

Posted by BonnieMcMurray@reddit | sysadmin | View on Reddit | 4 comments

I've inherited the management of an EMC VNX5700 at work. [Looking at the whitepaper](https://www.infranetgroup.com/wp-content/uploads/2014/07/vnx.pdf), it seems like this model should be able to do LUN snapshots, However, when I right-click a LUN, there are no snapshot options. They're pool LUNs and not RAID group LUNs, so according to that whitepaper, snapshots should be possible. And yet...nothing. Does anyone have any insight on this?

What you are able to do in a VNX is entirely dependent on what licenses you have installed on the array. That being said, the VNX interface is confusing, and it is possible you have the option but are in the wrong place. It's been multiple years since I've used one though so I can't offer further guidance.

Yeah, I had a suspicion it could be license-related. I believe I'm doing the right thing, per a couple of videos I watched. The option just isn't where it's supposed to be.

From my recollection there are actually two types of LUN snapshots in a VNX. An older style, and a newer higher performance version. I do think they are in different places. Found this article referencing this. Older style is snapview, newer is vnx snapshots. https://www.storagefreak.net/2014/07/emc-vnx-snapshots
