  • 1.  Host Maintenance Mode

    When using Maintenance Mode on an ESXi host, do I need to shutdown all VMS first? Do I also have to migrate the VMs or is shutting them down enough while in Maintenance Mode? Thanks!

    Hello ITMgrWynne,

     

    Considering vMotion network is setup and all the VMs are running on shared storage , If Host is part of DRS enabled cluster :

        a) Placing the host is maintenance mode will migrate the VMs (Powered on/off) to other hosts in the cluster , provided the DRS mode is set to automatic. 
        b) Manual migration will be needed if the DRS mode is set to Manual.

    Alternatively , you can choose to power-off the VMs (if no production impact) and then place the host in maintenance mode. There is no need to migrate the powered off VMs.
