You must complete this checklist before beginning the imaging process. It is important that each item in the checklist is set to the specified value, otherwise imaging may fail. You may want to print this checklist and checkmark each row as you verify the setting.

For more information on any item in this table, see Setting up your Environment for Imaging.

Table 1. Pre-Imaging Checklist



Review the Bill of Materials (BOM) and verify that there are no discrepancies between the BOM and the hardware being used. If there is a discrepancy, contact VMware Support.

Review the VMware Compatibility Guide and verify you have the supported server models, disk and storage adapter models, and switch models.

Verify that the physical racks are wired according to the wiremap. See Rack Wiring.

Confirm that the inter-rack switches are not connected to the ToR switches.

The VIA VM must be connected only to the private network - there should be no external network connections in place before imaging.

Validate that BIOS Settings for all components are correct. See BIOS Settings.

Ensure that all servers are powered off.


This is a new requirement for Cloud Foundation 2.3. All servers must be powered off, otherwise imaging will fail.

Ensure that switch versions are supported. See Network Switches.

Verify that firmware settings are set correctly as per the BoM.

Connect each device in the rack to both PDUs.

Verify that the cable bend radius is proportionate to the external diameter. See Network Cables.

Verify that cables are properly routed and labeled.

Test cables to ensure that installed cabling links provide the transmission capability to support the required data communication.

Verify that each server has redundant power supplies and that each power supply is connected to a separate rack PDU.

Ensure that servers and switches have the same airflow direction.

Verify that switches have redundant power supplies and each power supply is connected to a separate power strip.

If you are using a management host to image your system, ensure that:

  • A supported version of ESXi is installed on the management host. For the supported version, see the VMware Cloud Foundation Release Notes.

  • The Allow virtual machines to start and stop automatically with the system option is enabled.

  • IP address is assigned to the vmk0 kernel interface.

  • SSH is enabled on the management host.

  • The access VM, VIA VM, and jump VM meet the required hardware configuration. See Virtual Machines.

  • The required software has been installed on the VMs. See Virtual Machines.

Ensure that there are no DHCP or TFTP servers on the network that VIA will connect to for imaging the rack. VIA uses DHCP to assign IP addresses to the rack components, and any external DHCP servers can cause imaging to fail. Disconnect the uplink cables on the TORs to limit exposure.
