The LSI Storage Authority (LSA) is a web-based application that enables you to monitor, maintain, troubleshoot, and configure the Broadcom ® MegaRAID products. The LSI Storage Authority graphical user interface (GUI) helps you to view, create, and manage storage configurations.
Monitoring and Configuring: LSA lets you monitor the controllers and configure the drives on the controller.
It displays the status of the controller cards, virtual drives, and physical drives on the controller. The device status icons are displayed on their respective pages to notify you in case of drive failures and other events that require your immediate attention. Real-time email notifications on the status of the server are sent based on your alert settings. The system errors and events are recorded and displayed in an event log file. Additionally, you can also import or clear foreign configurations.
Maintaining: Using LSA, you can perform system maintenance tasks, such as updating the controller firmware.
Troubleshooting: LSA displays information related to drive failures, device failures, and so on.
It also provides recommendations and displays contextual links, helping you to easily locate the drives and devices that have issues and troubleshoot them. You can also download a complete report of the all the devices and their configurations, properties, and settings and send it to the Support Teams for further troubleshooting.
Personality Management: The Personality Management solutions for MegaRAID controllers support personality modes in the form of a new JBOD (Just a Bunch of Drives) personality.
This new JBOD personality is a unique personality derived from the standard RAID personality with additional features. The additional features that the JBOD personality provides are:Switching between behavior modes; you can switch between JBOD and None.
