Vsphere ESXI Host Yellow Triangle Warning?

Vsphere ESXI Host Yellow Triangle Warning?

Are you seeing yellow triangle warning on ESXi hosts on vCenter? What could be the reason you are seeing those warning? Can these warnings be disabled?

The reason you see the yellow triangle/exclamation mark on ESXi host is when you enabled SSH (Remote) and the ESXi Shell for Management of host from Console or web client or VSphere client.
