shrinking vplex voulmes

Question

Hi

I have one query about shrinking vplex voulmes since we have vPlex with Local configuration .

As I have EMC Unity back end array where in 4TB LUN created and presented to ESXI host via vPlex. Since I expanded LUN size from 4 to 6TB from back end array and then from vplex discovered New LUN Size and also i m able to see new size from vMware ESXi host under datastore properties .(I have not extended yet new size of storage from vmware datastore)

But for some reasons, now I have to shrink the LUN size back to original LUN Size(from 6TB to 4TB),so please can someone help how to shrink volume/LUN from vplex and back end array respectively .

Below are few more details to understand setup.

Vplex: Vplex Local v6.0

Single Cluster

2 Directors

Back end array is EMC Unity

No recovery Point configured .

Thanks in advance for your support.

VPLEX does not support lun shrink at this time. You would need to take the lun away from vplex and represent it as if you were doing an encapsulation.

Hi Ankur,

Thanks for your response.

To achieve desired requirement (shrinking the volume) ,can below method work fine

*Create new LUN with required Size in the array and present to vPlex

*Migrate Volume data from existing Volume into new volume using mobility option in vplex

*Then decommission the old volume and LUN from vplex and array respectively .

Thanks

You cannot migrate to a smaller volume using the mobility function. Only same size or larger. The method I mentioned is the only way to do it unless you want to us vmotion
