VMware: Exiting hung maintenance mode on ESX Server (9639912)

June 3rd, 2009 No comments

The following solution describes how to exit a hung maintenance mode from Virtual Infrastructure Client or from the command line on the service console of the ESX Server host.

Note: Before you begin please refer to KB1003490 for important information on restarting the mgmt-vmware service.

To exit from a hung maintenance mode, try the following: 

  • Disconnect the Virtual Infrastructure Client (by closing it) and reconnect to the ESX Server system, to see if the option exit maintenance mode appears. If this works, there was a problem refreshing the information known to the Virtual Infrastructure Client.
  • Try restarting the management agent. This shouldn’t affect any running virtual machines and often clears hung tasks.  However prior to ESX Server 3.0.1 (and in ESX Server 3.5.x issuing this command will cause virtual machines to restart if the option "autostart on boot" is set inside VirtualCenter Server.  From the service console of the ESX Server host, type:  # service mgmt-vmware restart
  • Try exiting maintenance mode using the vimsh command.
