A consultant completes a new cluster installation and tries to update the firmware using LCM.

The error encountered during the LCM operation suggests a failure in reading a file, which might be linked to the foundational services of the cluster. The genesis.out log file is essential for troubleshooting issues related to cluster initialization and fundamental operations. This file logs the activities of the Genesis service, which is responsible for managing and monitoring the lifecycle of cluster services, including LCM tasks. In case of errors during LCM operations, the genesis.out log provides detailed insight into what might have gone wrong during the process, making it the appropriate log to check in this scenario.
