Hi everyone

Running esxi 6.0u3 with block based vVol.

Cisco UCS with fnic driver 1.6.0.33 (needed to enable vVol)

Unity 4.1.1.latest

When taking and removing snapshot the VM loses network connectivity for 3-6 seconds depending on size.

Doing the same thing with a VMFS datastore works perfectly. (snapshot with/without memory)

I'm guessing the error is on the Unity or with the VASA-integration.

Anyone running block based vVol on unity? Does anyone have any similar issues or know how to troubleshoot it?
