Witness host
About this task
Witness host interfaces are dependent on the installed host.
Interfaces for the Witness host include:
● A network-accessible host interface
● Witness serial connection to the host
Documentation should be found online for the installed Witness host capabilities.
Witness serial communication
About this task
NOTE: The default VMware login for the Witness ESXi factory image is: root / @witness123!
The ESXi host on the Witness node supports standard ESXi and vCenter interface methods.
The ESXi serial console is also accessible through serial communication with the Witness.
NOTE:
Accessing Witness serial connection:
1. Access the Witness OS interface by using the Witness IP captured from the serial connection. Refer screenshot.
2. Go to "Actions", select "Services", Enable Secure Shell (SSH).
3. Go to "Actions", select "Services", Enable ESXi Shell.
4. Access Witness with SSH connection by using Witness IP address.
Witness power operations
About this task
The Witness node must be installed into a properly configured chassis. See Installing the Witness for details.
Witness power operations are accessible through:
● Witness front panel power button
●
iDRAC
1. GUI
2. Redfish
3. RACADM
4. IPMI
5. CPLD
● Witness host interfaces
● Chassis manager serial connection
The CM controls power to the Witness. Auto power-on for the Witness is enabled by default in the CM and will power on the
Witness once its presence is detected. As previously mentioned in Installation requirements, the CM will run several checks to
ensure that various system fans are following expected behavior. If these checks fail, then the CM will not supply the Witness
with power.
The below block and state diagrams add additional detail to the Witness power behavior as seen by the CM.
