Why are VMs in my RHEV environment pausing during Netapp I/O controller giveback?
Issue
- While simulating a NetApp controller crash the takeover correctly works, with the secondary controller taking the I/O traffic and the virtual machines continue to run, but during the giveback to restore the I/O to the first controller the VMs become paused and do not automatically start.
Environment
