Cloned volume reattach

[PKKASTURI]

Hi Techies,

I've a question. I did a cloned volume and after that i split the volume.

After some time i've modified the date on primary volume, Now i would like to copy the modified contents to the cloned volume. Is there any way that we can reattach the cloned volume and copy the modified contents from primary volume.

I've tried the options with vol clone but unable to find it.

Any thoughts?

Thanks,

Phani

No, it is not possible. Clone is based on snapshot. Any change on source which happened after this snapshot had been created is invisible on clone.

If you can afford full copy, you could split clone and run “snapmirror resync” and “snapmirror update”. This would completely wipe out any changes on clone since last common snapshot and resync it with source.
