We have a new implementation of vSphere ESXi 7.0.3 with 4 hosts. Hosts are connected to an SN2410M switch and an Alletra 6000 storage. We are experiencing network connectivity issues on all VM's on all hosts. Additionally we are getting the below alarm intermittently in vCenter.
"vSphere HA detected that host <host name> is in a different network partition than the master <cluster name> in <DCname>"
When this alarms occurs the ESXi host gets disconnected.
Support has checked the network and could not find any faults. Any suggestions?
