Does Live Migration work when no VDS?

Wondering if Live Migration of VM's should work if setup correctly without having VDS (which I don't on standard plan)?

Had an issue with a 1 of 3 hosts coming offline and VMS on it did not get migrated to other hosts even though there was plenty of spare capacity on other 2 hosts.

If so (should work without VDS) is there maybe some settings we should check to assure VM's next time to get automatically migrated when a host comes offline?

FYI: using netapp fas2240-2 for shared storage and running 6.7.

Thanks ahead of time.

Hi there!

Assuming you mean VMWare HA, no, distributed switching is not a requirement, however having at least two datastores is, to enable datastore heartbeating. In terms of your question, "Live Migration" is a specific capability of vmotion - notably it is not the feature used to manage VM availability if a host goes down.

VMWare's forums might be a better place to ask, but their documentation for configuring vSphere HA for 6.7 is available here as a starting point.

However, by my reading of their compatibility page, you are not running a supported combination - for all releases of vSphere 6.7, ONTAP 9.3 is the minimum version, while for the FAS2240-2, ONTAP 9.1 is the maximum version. vSphere 6.5 U3 will support whatever you're running on the FAS2240 however.

It's a standards compliant communication protocol, so it should work, but in the end it is up to VMWare if they choose to support it, and they do not.

Hope this helps!
