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?
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
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.
