Host cannot communicate with one or more other nodes in the vSAN enabled cluster

There can be possibility of error such as:

Host cannot communicate with one or more other nodes in the vSAN enabled cluster

esp. after some kind of network disconnection OR incorrect shutdown / boot procedure.

To solve that:

ping from one host to all other hosts and validate it is working.
In case of more than one TCP/IP stack such as in case of VxRail use: Test connectivity when using multiple tcp/ip stacks
Check output of below command to validate whether vSAN is properly enabled on node or not.
```
esxcli vsan cluster get
```
Put host in maintenance mode at ESXi level and reboot.
At vCenter level it may not enter successfully
