You can perform maintenance on instant-clone VMs by putting the ESXi hosts into maintenance mode. You can also use the instant-clone maintenance utilities to perform manual maintenance on instant-clone VMs.

About this task

To use the instant-clone utilities, see Instant-Clone Maintenance Utilities.

You can use vSphere Web Client to put the ESXi host into maintenance mode. The ESX host maintenance operation automatically deletes the parent VMs from that ESXi host.


After the ESXi host is put into maintenance, you must wait approximately five minutes before performing any actions on instant clones after the ESXi host performs entering or exiting operations.


  1. Log in to vSphere Web Client.
  2. Select the ESXi host that you want to put into maintenance and clickMaintenance Mode > Enter Maintenance Mode.
