Vsnap?
I have a EVA3000 disk-array with Business-Copy license.
I read that EVA supports three types of clones:
- traditional snapshots, using same space of original Vdisk
- Vsnap or virtually capacity-free snapshot
- snapclone
I'm interested in Vsnap but I wasn't able to find this option in CommandView; I see only options for traditional snapshot.
How can I create a Vsnap?
Thanks

Re: Vsnap?
I'm not sure which version of CV-EVA you have, but I have attached a picture from V3.3 where a 'Vsnap' is selected.

Re: Vsnap?
But related help says:
"Allocate on demand ├в Reserves the space a Vdisk requires on the physical disk, but only as data is stored in it."
Thus this is not a virtually capacity-free snapshot as marketing adverti

Re: Vsnap?
The original data *must* be stored somewhere for the snapshot to retain its point-in-time view when the data of the original virtual disk is changed.
How did you think a "virtually capacity-free" snapshot worked?

Re: Vsnap?
- Capacity Used: 0 GB
- Initial Allocation: 0 GB
After some disk activity:
- Capacity Used: 2 GB
- Initial Allocation: 0 GB
Perpaphs, before I made some mistake.
Thank you for clarification
