Restarting the Management agents on an ESXi or ESX host

  • You cannot connect ESXi/ESX to VirtualCenter / vCenter Server.
  • You cannot connect directly to the ESXi/ESX host from the VMware Infrastructure Client / vSphere Client.
  • You cannot stop or start a virtual machine.
  • A virtual machine is shown as running in vCenter Server when it is not.
  • vCenter Server displays the error:
    Virtual machine creation may fail because agent is unable to retrieve VM creation options from the host

 

Restarting the Management agents on ESXi

To restart the management agents on ESXi:

From the Direct Console User Interface (DCUI):
  1. Connect to the console of your ESXi host.
  2. Press F2 to customize the system.
  3. Log in as root.
  4. Use the Up/Down arrows to navigate to Restart Management Agents.
    Note: In ESXi 4.1 and ESXi 5.0, 5.1 and 5.5, this option is available under Troubleshooting Options.
  5. Press Enter.
  6. Press F11 to restart the services.
  7. When the service has been restarted, press Enter.
  8. Press Esc to log out of the system.
From the Local Console or SSH:
  1. Log in to SSH or Local console as root.
  2. Run these commands:
    /etc/init.d/hostd restart
    /etc/init.d/vpxa restart
    Note: In ESXi 4.x, run this command to restart the vpxa agent:
    service vmware-vpxa restart
  3. Alternatively:
  • To reset the management network on a specific VMkernel interface, by default vmk0, run the command:
    esxcli network ip interface set -e false -i vmk0; esxcli network ip interface set -e true -i vmk0
    Note: Using a semicolon (;) between the two commands ensures the VMkernel interface is disabled and then re-enabled in succession. If the management interface is not running on vmk0, change the above command according to the VMkernel interface used.
  • To restart all management agents on the host, run the command:
    services.sh restart
    Note: For more information about restarting the management service on an ESXi host, see Service mgmt-vmware restart may not restart hostd in ESX/ESXi (1005566).
Restarting the Management agents on ESX

To restart the management agents on an ESX host:

  1. Log into your ESX host as root from either an SSH session or directly from the console.
  2. Run this command:
    service mgmt-vmware restart
    Caution: Ensure Automatic Startup/Shutdown of virtual machines is disabled before running this command or you risk rebooting the virtual machines. For more information, see Restarting hostd (mgmt-vmware) on ESX hosts restarts hosted virtual machines where virtual machine Startup/Shutdown is enabled (1003312) and Determining whether virtual machines are configured to autostart (1000163).
  3. Press Enter.
  4. Run this command:
    service vmware-vpxa restart
  5. Press Enter.
  6. Type logout and press Enter to disconnect from the ESX host.
    If this process is successful, it appears as:
    [root@server]# service mgmt-vmware restart
    Stopping VMware ESX Server Management services:
    VMware ESX Server Host Agent Watchdog [ OK ]
    VMware ESX Server Host Agent [ OK ]

    Availability report startup (background) [ OK ]
    [root@server]# service vmware-vpxa restart
