MegaCLI (MegaRAID Command Line Interface) is a command-line utility used to manage and configure LSI (now Broadcom) MegaRAID controllers in servers and storage systems. It provides powerful options for monitoring, troubleshooting, and maintaining RAID configurations, including creating and deleting virtual drives, checking disk health, rebuilding arrays, and retrieving detailed status reports.

Despite its capabilities, MegaCLI has a complex syntax, requiring users to reference extensive documentation or use scripts to simplify common operations. It has been largely replaced by StorCLI, which offers a more user-friendly interface while maintaining similar functionalities.
