It is part of the Optimization and Migration process. After you scan under the Optimization and Migration tab, there will be a list of machines under the misaligned folder on the left hand frame. Under that there will be a "online migration" sub folder. Once you select that subfolder a list of VM's that are eligible for the online optimization will be listed. You will then select

Each machine individually or select "migrate all" which will launch a wizard. After the wizard has been completed VSC will then create the optimized datastore and migrate the VM's.
I would reach out to your SE for a more in depth overview of when to use this tool and the caveats etc.

Does anyone know how to get, or make, or create a VMDK (FC) LUN to be optimized? I didnít read it in the admin guide, or release notes. I have created a new lun viaNetapp/vshpere plugin; tried to use an existing lun, created a new lun etc. Every instance we see the lun as not optimized.
∑ Using DOT 7.3.3p2
∑ 6040ís HA
∑ FC license
∑ All luns are set to ALUA/yes
∑ Vshpere is 5 and running esxi5 and esx4.x on the hosts

I'm frustrated they seemed to have released it before its done - see my post from 2 weeks ago
"VSC 4 missing VAAI and getting no VMs for aligned/not aligned"
Are people successfully using it to align VMs ?
We aligned all our VMs over a year ago when Netapp cited it as a prereq for helping us solve a latency issue.
I forget how I found out about VSC 4.0 - but I usually get this info from RSS feeds of blogs.
If the online alignment is production ready I can't believe they didn't tell folks earlier this was in the pipeline since it would save folks TONS of downtime we went through last year.
I remember asking back in June 2009 about "Adding VM re-alignment to SVMotion - which API?"
at that time the APIs were not thereÖ

This maybe off topic, but I am a bit frustrated here.
Is there anyway ANYONE knows of a way one becomes abreast of new updates to Netapp software one has purchased? We have someone doing re-alignments during the late evening taking downtime to re-align these windows 2003 vms.
Any help is appreciated.
BTW, thanks Peta for posting this. This is my current method of knowing what's out there and what others are doing.
