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:

  1. 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
  2. Check output of below command to validate whether vSAN is properly enabled on node or not.
    esxcli vsan cluster get
  3. Put host in maintenance mode at ESXi level and reboot.
    At vCenter level it may not enter successfully
