Does the BC 2.3 for EVA enable me to recover the parent volume directly from the Snapshot? If yes? what is the commmand used?. Do I have to copy the snapshot mounted volume and paste it on the parent volume from the host side?
Solved! Go to Solution.

No, BC for the EVA does not allow to do a resynch of volumes. (Neither with snapshots nor with snapclones)
With snapshots you need to copy the snapshot via a host; with snapclones you can unpresent the parent volume and mount the clone!
This is what has changed with BC2.3:
- Support for new drives
- Support for Snapshots between Vraid types (0, 1, 5) within the same disk group
- Support for Snapclones between different Vraid types and across disk groups including FATA disk groups
- Support for installation on Windows server
BC can be installed on either the SMA or a customer supplied W2003 EE server
- New licensing model

Re: BC 2.3
Be carefull with allocate-on-demand snapshots:
remember that if you copy the data from the snapshot unit back to the parent volume, you will overwrite all old data. This will require a lot of space to save the previous data for the snapshot.
