Reclaiming Space in a volume and LUN

Good afternoon all,

 

I was asked a question this morning that I wasn't sure how to answer...

 

The following is our situation:

 

This is regarding using a FAS3240 in a virtual environment (vSphere).

 

I am looking at the NetApp tab in vCenter (VSC4.1)

I select on of my datastores and see the following (picture attached):

 

DataStore Usage (19%)

LUN Usage (60%)

Volume Usage (48%)

Aggregate Usage (62%)

 

A few facts:

From Virtual Centre, it looks like I have 81% free space on my 2.7TB LUN

From NetApp console, it looks like I onjly have 40% free space on my 2.7TB LUN

 

My assumption is the following:

The reason the LUN usage is @ 60% is because at one point in time, that LUN was 60% full.

Using Storage vMotion, much of that data was relocated to another LUN or DataStore.

There is a lot of 'white space' on that LUN.

 

Question:

Is there a way to recuperate that whitespace ?

NOTE:  Deleting the LUN and Volume and re-creating will do it but this is not efficient.

 

Thanks.
