Identifying a service action by using sensor and event information for the 8001-22C and 8005-22N

You can use the sensor and event information from the system event log to determine a service action to perform for the IBM® Power® System S822LC for Big Data (8001-22C) and IBM Hyperconverged Systems powered by Nutanix (8005-22N).

If you have not done so already, complete Identifying a service action by using system event logs. Then, use the following table to determine the service action to perform.
