Why are network adapters not detected during ESXi installation

Cause:
This issue occurs due to one of the following reasons:
  • The ESXi image does not contain the latest version of network drivers, for Network Daughter Cards (NDCs) or network adapters used in Dell EMC servers.
  • PowerEdge server does not have an NDC installed.
  • The NDC installed on the PowerEdge server is faulty
  • PowerEdge server has an NDC installed, but the NDC setting is disabled in the BIOS or UEFI.
Resolution:
  1. Use the latest available Dell EMC customized ESXi image, which contains drivers for all NDC or network adapters that are supported on Dell EMC PowerEdge servers.
    NOTE: For more information about downloading the Dell EMC customized ESXi image, see the Downloading the Dell EMC ESXi installer media section.
  2. Check if the NDC is working correctly.
  3. Check if the NDC setting is enabled in BIOS/UEFI.
    NOTE: For more information about installing and configuring the NDC on a PowerEdge server, see Dell EMC PowerEdge hardware Owner’s Manual at https://www.dell.com/poweredgemanuals.
