It was set to MODE 1
I have tested on both FLARE 30. 008 (really old) and the newest available to CX4

Because i dont know if it is working. I can see that it is enabled in the config, but is enable the same af working?
See this how to watch if the offload is being used or not while doing a clone/deploy/storage vMotion.
any updates on this? we are seeing the issue as well, thanks,
some luns show unknown, unsupported, all new luns with vmfs5 show unknown as well
anyone try 523 yet?
The EMC is responding to the test packets with a failure do to the fact that it thinks VAAI will only work on LUNS under 2TB.
EMC needs to update FLARE code on CX4 to support VAAI 5.0
EMC may or may not do this…
seems to be the response i am getting as well for the cx4, but unknown about the vnx, if the awnser is <2tb for vmfs5,
that is crap, and they need to fix it too!
We have two cx4-480s, one of them I’ve updated to 4.30.000.5.522. The other one is at 4.30.000.5.511. They both have a mix of >2tb and <2tb luns. The one that is updated to 522 seems to no longer be affected, all luns are showing supported. The one at .511 still shows unknown for all the >2tb luns and supported for the <2tb luns. I don’t recall seeing anything about vaai in the .522 release notes, but it looks to be working.
Also you need to set the failover mode to 4. When I set the failovermode to 4 both my systems went to "supported"
Versions are 04.30.000.5.522 and 04.30.000.5.507
not when they are over 2tb,
here is the offical word from EMC:
I'm happy to confirm from Engineering that VNX supports VAAI with >2TB luns at R31.502 and up
Per our conference call, Clarion supports luns larger than 2 TB on ESX At R30.522 and up
Kind Regards "
Hi. What status now? I want to make 7 TB LUN on EMC CX4-120 Pool with FAST VP, ALUA mode, Round Robin and vSphere 5.0 Update 1. Is it work and officially supported by EMC and VMware?
If i have more 50 VM's and such big LUN - does VAAI Hardware Locking in EMC CX4-120 works well ?
Update to the latest 30 FLARE and its resolved
Its worth noting:
VAAI on CX4 with vSphere 5 is not officially supported. It works well, but due to a change in how VMware does the testing, they removed our (EMC's) CX4 certification for VAAI only.
See this blog post for details:
We turn OFF all VAAI parameters after migrate to vSphere 5.0 Update 1. EMC tells do it because we can see disconnect from VMFS datastores with turned on VAAI.
What's the issue when using the EMC CX4-240 with the Flare 04.30.000.5.525 ?
