Does anyone know how to get, or make, or create a VMDK (FC) LUN to be optimized? I didn't 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.
RE: VSC 4 and online alignment - anyone used it in anger?
[In reply to]
* Using DOT 7.3.3p2
* 6040's 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 there...

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.
