An administrator is applying patches to a batch of ESX1 5.x hosts in an under-allocated HA/DRS cluster. An attempt is made to place the host into maintenance mode, but the progress has stalled at 2%.

– If an ESX host is a part of VMware High Availability (HA) or DR’S cluster, check the Admission Control settings. You may have to disable this option if there are not enough resources to ensure fail over capacity.
– If you want vCenter Server to migrate your running virtual machines automatically to other hosts when placing your host in maintenance mode, DR’S must be enabled in your cluster in the Fully Automated mode.
