Use this information to review event messages and resolve many errors.
IMM messages When a hardware event is detected by the IMM on the upper or lower compute node of a Flex System x222 Compute Node, the IMM logs that event in the system-event log in the affected compute node. In addition, the IMM sends that event to the CMM and to the Flex System Manager management software (if installed).
UEFI diagnostic codes UEFI diagnostic codes can be generated when a compute node starts up or while a compute node is running. UEFI diagnostic codes are logged in the IMM event log in the compute node.
