Hi Anyone can take a look at the host? What is wrong with it? sometimes the storage in this host cannot be see or opened. Thanks
You can check the ILO or IDRAC console and see from the hardware perspective if the host is fine.
looks like this host has lost management connectivity with vCenter. Can you ping the ESXI mngt ip address from a client which has network connectivity??? Or better still Putty into your other host (192.168.1.20) and ping using the shell to your other host.
