Stopping, Rebooting, and Examining Hosts with vicfg-hostops
You can shut down or reboot an ESXi host using the vSphere Client or the vicfg-hostops vCLI command. No equivalent ESXCLI command is currently available.
Shutting down a managed host disconnects it from the vCenter Server system, but does not remove the host from the inventory. You can shut down a single host or all hosts in a datacenter or cluster. Specify one of the options listed in Connection Options in place of <conn_options>.
Single host. Run vicfg-hostops with --operation shutdown.
vicfg-hostops <conn_options> --operation shutdown
If the host is not in maintenance mode, use --force to shut down the host and all running virtual machines.
vicfg-hostops <conn_options> --operation shutdown --force
All hosts in datacenter or cluster. To shut down all hosts in a cluster or datacenter, specify --cluster or --datacenter.
vicfg-hostops <conn_options> --operation shutdown --cluster <my_cluster>
vicfg-hostops <conn_options> --operation shutdown --datacenter <my_datacenter>
You can reboot a single host or all hosts in a datacenter or cluster.
Single host. Run vicfg-hostops with --operation reboot.
vicfg-hostops <conn_options> --operation reboot
If the host is not in maintenance mode, use --force to shut down the host and all running virtual machines.
vicfg-hostops <conn_options> --operation reboot --force
All hosts in datacenter or cluster. You can specify --cluster or --datacenter to reboot all hosts in a cluster or datacenter.
vicfg-hostops <conn_options> --operation reboot --cluster <my_cluster>
vicfg-hostops <conn_options> --operation reboot --datacenter <my_datacenter>
You can display information about a host by running vicfg-hostops with --operation info.
vicfg-hostops <conn_options> --operation info
The command returns the host name, manufacturer, model, processor type, CPU cores, memory capacity, and boot time. The command also returns whether vMotion is enabled and whether the host is in maintenance mode.
