Getting Witness host network information

Once a valid network connection is applied to the Witness, host IPv4 and MAC address information are accessible over typical iDRAC interfaces of any compute node that is connected to the same CM. This data is sent by the host OS agent to the CM. The CM stores and provide this data to any connected iDRAC through a shared CPLD memory-map.

Host network information can be found through the following methods:

  • iDRAC
    1. iDRAC GUI
    2. Redfish
    3. RACADM
    4. IPMI
    5. CPLD
  • Witness serial connection
  • Chassis manager serial connection
