After upgrading the ESXi to version 7.0 u1, the host cannot communicate with the vcenter. I also try to communicate via ssh with the host but I have problems connecting ( ran Ping between my laptop and the ESXi, failing connectivity ). This host is configured via dsv.
Which ESXi version/build did you upgrade from?
Can you confirm that ESXi 7.0U1 supports your hardware (e.g. network adapters)?
Did you upgrade using a vendor customized ESXi image (which may include additional drivers that are required for your hardware)?
