You can log in to each ESXi hosts using either the vSphere Client or the ESXi shell. If you type the name of the OS in the Name box, the app will most likely automatically select the type and version for the OS. You’ll be guided through the process by a wizard that first asks which OS you’ll be installing. # esxcli system maintenanceMode set -e true -m noAction Open up your VM app and click the button to create a new virtual machine. Run this ESXCLI command and ensure that the No Action option is selected when you enter Maintenance Mode:.You can either do this by logging directly in to the ESXi Shell and running the ESXCLI command locally or you can invoke this operation on a remote system using ESXCLI.
This operation must be done using one of the CLI methods that supports setting the vSAN mode when entering Maintenance Mode. Place all ESXi hosts into Maintenance Mode.For more information, see Using ESXi Shell in ESXi 5.x and 6.0 (2004746). This makes the vSphere Web Client unavailable. Shut down the vCenter Server virtual machine.For more information, see the Monitor the Resynchronization Tasks in the Virtual SAN Cluster section in the Administering VMware Virtual SAN. If you have more than one cluster network listed in Network for live migration, you should change the priority order to avoid having live migration and Cluster Shared Volumes use the same network. Ensure that there are no vSAN components currently resynching. When you configure a network for live migration for a specific virtual machine, the setting is global and therefore applies to all virtual machines.
Note: VMware recommends to migrate the vCenter Server virtual machine to the first ESXi host, so you can easily find the virtual machine when powering on your vSAN cluster again.
