    vSAN cluster fails when host put into maintenance mode and disconnected from network

    digitalbath Novice


      We have a weird issue that I can't figure out


      We have a 2 node vSAN cluster and a witness server all on the same layer 2 network for management/witness traffic


      The 2 nodes also have direct connect 10G for vSAN data (WTS has been implemented)


      Everything is working and healthy but if I put 1 node into maintenance mode and disconnect the management NICs (not even vSAN data as that is DC) (we were doing switch maintenance)


      The VMs on the other node fail and VMware says connectivity to storage lost...


      Any ideas?


      I logged a ticket to VMware and they can't figure it out yet...
